That moment of anticipatory silence
Like the crackle of a speaker before the song starts.
Like the inhale of breath before you speak.
Like the moment after the flash when you're waiting for the thunder
That's what you feel like.
There’s no such thing as the Devil.
The Devil is a Christian invention; the Christian invention used to put a stopper in the Old Religion and propel the massacre of 9 million people on its way to power. It succeeded. Almost.
It’s 2023 and I am seeing more and more Pagans and Witches rise from the ashes, and so this post is for you.
Witchcraft, Mediumship, Energy Work and Spiritualism do not need nor want this Christian lie in their teachings. It has been put there to STOP us from working with Spirit/Source. If you work with Source, you will receive abundance in this life for yourself AND others. Why would the self-appointed select few want the majority to access this wisdom? It would stop their own power in the form of control that they firmly believe is theirs for the taking. This idealism is a folly.
Fear is unnecessary for stepping through the veil, as the “Hell” or “Demons” that we are conditioned to expect is already occurring here on Earth by those who taught you them. The invention of organised religion has created ways in which to perpetuate fear - this manifests what we are scared of. Slavery, trafficking, famine, disease, senseless murders, conquer & divide - this is the Hell that we, as a collective, have produced over the centuries under the guise of false religions and what they are propped up by; Capitalism, Corporate Greed, Money.
The Hell that so many are afraid of is already here and now to millions of our people. Because we create it. We allow fear to seep into our lives and eat us alive. We allow the toxic drips of Capitalism and Elitism by simply paying attention. Demons? They are already in Congress, multi-billion dollar companies, Churches. They lurk in your banks, in your shops, in your workplaces, in your homes. Demons are the 1% who control the Citizens of this planet by one simple tool, fear. It works so well that beings from one country will ignore the beings of another. We ignore what is happening to our one true God; Gaia, Earth, Home. We allow the murders of our collective selves because we have different skin colours, different genders, different ideas.
Fear can bring the strongest to their knees and weep.
So if we create our own Hell by succumbing to fear and accepting the global rules applied, is it possible, then, to create our own Heaven? We manifest what we want to see in our world. If most are scared, it comes to reason that most would inadvertently manifest fear of Hell right here. Can we change the narrative? There is nothing to fear in Spirituality, Witchcraft, Energy Work. The powers that be would like you to believe so as it ensures their futures in power. It’s Christian hogwash designed specifically for them. To keep you subservient.
I find that many beginners who come into these circles are afraid due to what we are sold throughout life regarding The Veil - it’s here that I want to say that there is nothing to be frightened of. If you approach your way of life and your practice from a place of positive energy, you will manifest great things. Approach it from a place of fear and this is where Hell begins.
Don’t be afraid of the facets of this movement. Why be afraid of the Witches and Sensitives? Be afraid of the ones who burned us alive.

Stupid thought I kind of believe: no one can agree on what "neoliberalism" means, but extensionally it's "whatever we've been doing, economically, for the past few decades."
Therefore, a major component of neoliberalism must be degrowth. It might be neoliberalism's fatal flaw!
This is probably random but Lloyd & Jay need to have a fight scene in a kitchen at some point. I need to see both of them exploding appliances and quoting Starfarer lines at some villain because c'mon, they just have to.
Just found out the guy I’ve had an on and off crush on for like almost what feels like an eternity is getting married! For some reason, I always thought my heart would break, but I’m actually feeling happy. I feel like I don’t have to put myself through anymore and am finally free to just live my life and not care about what he thinks. Guys, I’m a stupid person, but I’ve learned. All I’m hoping is that he stays married so there’s not a possibility of that crush coming back anymore. I say that because a lot of people who I grew up with are getting divorced like after a year they’re married, I just hope he doesn’t. IM FINALLY FREE!!!!!!!!!!
Is it okay for a masculine guy to be drawn to women with more feminine traits? I don't know why I'm stuck on this, but I find myself really attracted to feminine energy—not the needy or childish kind, but something in between that feels right for my soul. I'm trying to figure out if I should go for someone with a more feminine vibe or someone with a more masculine energy.

Weird Magnetic Behavior in Space
In between the planets, stars and other bits of rock and dust, space seems pretty much empty. But the super-spread out matter that is there follows a different set of rules than what we know here on Earth.
For the most part, what we think of as empty space is filled with plasma. Plasma is ionized gas, where electrons have split off from positive ions, creating a sea of charged particles. In most of space, this plasma is so thin and spread out that space is still about a thousand times emptier than the vacuums we can create on Earth. Even still, plasma is often the only thing out there in vast swaths of space — and its unique characteristics mean that it interacts with electric and magnetic fields in complicated ways that we are just beginning to understand.
Five years ago, we launched a quartet of satellites to study one of the most important yet most elusive behaviors of that material in space — a kind of magnetic explosion that had never before been adequately studied up close, called magnetic reconnection. Here are five of the ways the Magnetospheric Multiscale mission (MMS) has helped us study this intriguing magnetic phenomenon.
1. Seeing magnetic explosions up close
Magnetic reconnection is the explosive snapping and forging of magnetic fields, a process that can only happen in plasmas — and it's at the heart of space weather storms that manifest around Earth.
When the Sun launches clouds of solar material — which is also made of plasma — toward Earth, the magnetic field embedded within the material collides with Earth's huge global magnetic field. This sets off magnetic reconnection that injects energy into near-Earth space, triggering a host of effects — induced electric currents that can harm power grids, to changes in the upper atmosphere that can affect satellites, to rains of particles into the atmosphere that can cause the glow of the aurora. Â
Though scientists had theorized about magnetic reconnection for decades, we'd never had a chance to study it on the small scales at which it occurs. Determining how magnetic reconnection works was one of the key jobs MMS was tasked with — and the mission quickly delivered. Using instruments that measured 100 times faster than previous missions, the MMS observations quickly determined which of several 50-year-old theories about magnetic reconnection were correct. It also showed how the physics of electrons dominates the process — a subject of debate before the launch.
2. Finding explosions in surprising new places
In the five years after launch, MMS made over a thousand trips around Earth, passing through countless magnetic reconnection events. It saw magnetic reconnection where scientists first expected it: at the nose of Earth's magnetic field, and far behind Earth, away from the Sun. But it also found this process in some unexpected places — including a region thought to be too tumultuous for magnetic reconnection to happen.
As solar material speeds away from the Sun in a flow called the solar wind, it piles up as it encounters Earth's magnetic field, creating a turbulent region called the magnetosheath. Scientists had only seen magnetic reconnection happening in relatively calm regions of space, and they weren't sure if this process could even happen in such a chaotic place. But MMS' precise measurements revealed that magnetic reconnection happens even in the magnetosheath. Â
MMS also spotted magnetic reconnection happening in giant magnetic tubes, leftover from earlier magnetic explosions, and in plasma vortices shaped like ocean waves — based on the mission's observations, it seems magnetic reconnection is virtually ubiquitous in any place where opposing magnetic fields in a plasma meet. Â
3. How energy is transferred
Magnetic reconnection is one of the major ways that energy is transferred in plasma throughout the universe — and the MMS mission discovered that tiny electrons hold the key to this process.
Electrons in a strong magnetic field usually exhibit a simple behavior: They spin tight spirals along the magnetic field. In a weaker field region, where the direction of the magnetic field reverses, the electrons go freestyle — bouncing and wagging back and forth in a type of movement called Speiser motion.
Flying just 4.5 miles apart, the MMS spacecraft measured what happens in a magnetic field with intermediate strength: These electrons dance a hybrid, meandering motion — spiraling and bouncing about before being ejected from the region. This takes away some of the magnetic field’s energy.
4. Surpassing computer simulations
Before we had direct measurements from the MMS mission, computer simulations were the best tool scientists had to study plasma's unusual magnetic behavior in space. But MMS' data has revealed that these processes are even more surprising than we thought — showing us new electron-scale physics that computer simulations are still trying to catch up with. Having such detailed data has spurred theoretical physicists to rethink their models and understand the specific mechanisms behind magnetic reconnection in unexpected ways.Â
5. In deep space & nuclear reactions
Although MMS studies plasma near Earth, what we learn helps us understand plasma everywhere. In space, magnetic reconnection happens in explosions on the Sun, in supernovas, and near black holes.
These magnetic explosions also happen on Earth, but only under the most extreme circumstances: for example, in nuclear fusion experiments. MMS' measurements of plasma's behavior are helping scientists better understand and potentially control magnetic reconnection, which may lead to improved nuclear fusion techniques to generate energy more efficiently.
This quartet of spacecraft was originally designed for a two-year mission, and they still have plenty of fuel left — meaning we have the chance to keep uncovering new facets of plasma's intriguing behavior for years to come. Keep up with the latest on the mission at nasa.gov/mms.

Things That Go Bump in the Gamma Rays
Some people watch scary movies because they like being startled. A bad guy jumps out from around a corner! A monster emerges from the shadows! Scientists experience surprises all the time, but they’re usually more excited than scared. Sometimes theories foreshadow new findings — like when there’s a dramatic swell in the movie soundtrack — but often, discoveries are truly unexpected.Â
Scientists working with the Fermi Gamma-Ray Space Telescope have been jumping to study mysterious bumps in the gamma rays for a decade now. Gamma rays are the highest-energy form of light. Invisible to human eyes, they’re created by some of the most powerful and unusual events and objects in the universe. In celebration of Halloween, here are a few creepy gamma-ray findings from Fermi’s catalog.
Stellar Graveyards
If you were to walk through a cemetery at night, you’d expect to trip over headstones or grave markers. Maybe you’d worry about running into a ghost. If you could explore the stellar gravesite created when a star explodes as a supernova, you’d find a cloud of debris expanding into interstellar space. Some of the chemical elements in that debris, like gold and platinum, go on to create new stars and planets! Fermi found that supernova remnants IC 443 and W44 also accelerate mysterious cosmic rays, high-energy particles moving at nearly the speed of light. As the shockwave of the supernova expands, particles escape its magnetic field and interact with non-cosmic-ray particles to produce gamma rays.Â
Ghost Particles
But the sources of cosmic rays aren’t the only particle mysteries Fermi studies. Just this July, Fermi teamed up with the IceCube Neutrino Observatory in Antarctica to discover the first source of neutrinos outside our galactic neighborhood. Neutrinos are particles that weigh almost nothing and rarely interact with anything. Around a trillion of them pass through you every second, ghost-like, without you noticing and then continue on their way. (But don’t worry, like a friendly ghost, they don’t harm you!) Fermi traced the neutrino IceCube detected back to a supermassive black hole in a distant galaxy. By the time it reached Earth, it had traveled for 3.7 billion years at almost the speed of light!
Black Widow Pulsars
Black widows and redbacks are species of spiders with a reputation for devouring their partners. Astronomers have discovered two types of star systems that behave in a similar way. Sometimes when a star explodes as a supernova, it collapses back into a rapidly spinning, incredibly dense star called a pulsar. If there’s a lighter star nearby, it can get stuck in a close orbit with the pulsar, which blasts it with gamma rays, magnetic fields and intense winds of energetic particles. All these combine to blow clouds of material off the low-mass star. Eventually, the pulsar can eat away at its companion entirely.
Dark Matter
What’s scarier than a good unsolved mystery? Dark matter is a little-understood substance that makes up most of the matter in the universe. The stuff that we can see — stars, people, haunted houses, candy — is made up of normal matter. But our surveys of the cosmos tell us there’s not enough normal matter to keep things working the way they do. There must be another type of matter out there holding everything together. One of Fermi’s jobs is to help scientists narrow down the search for dark matter. Last year, researchers noticed that most of the gamma rays coming from the Andromeda galaxy are confined to its center instead of being spread throughout. One possible explanation is that accumulated dark matter at the center of the galaxy is emitting gamma rays!
Fermi has helped us learn a lot about the gamma-ray universe over the last 10 years. Learn more about its accomplishments and the other mysteries it’s working to solve. What other surprises are waiting out among the stars?

Using All of Our Senses in Space
Today, we and the National Science Foundation (NSF)Â announced the detection of light and a high-energy cosmic particle that both came from near a black hole billions of trillions of miles from Earth. This discovery is a big step forward in the field of multimessenger astronomy.
But wait — what is multimessenger astronomy? And why is it a big deal?
People learn about different objects through their senses: sight, touch, taste, hearing and smell. Similarly, multimessenger astronomy allows us to study the same astronomical object or event through a variety of “messengers,” which include light of all wavelengths, cosmic ray particles, gravitational waves, and neutrinos — speedy tiny particles that weigh almost nothing and rarely interact with anything. By receiving and combining different pieces of information from these different messengers, we can learn much more about these objects and events than we would from just one.
Lights, Detector, Action! Â
Much of what we know about the universe comes just from different wavelengths of light. We study the rotations of galaxies through radio waves and visible light, investigate the eating habits of black holes through X-rays and gamma rays, and peer into dusty star-forming regions through infrared light.
The Fermi Gamma-ray Space Telescope, which recently turned 10, studies the universe by detecting gamma rays — the highest-energy form of light. This allows us to investigate some of the most extreme objects in the universe.
Last fall, Fermi was involved in another multimessenger finding — the very first detection of light and gravitational waves from the same source, two merging neutron stars. In that instance, light and gravitational waves were the messengers that gave us a better understanding of the neutron stars and their explosive merger into a black hole.
Fermi has also advanced our understanding of blazars, which are galaxies with supermassive black holes at their centers. Black holes are famous for drawing material into them. But with blazars, some material near the black hole shoots outward in a pair of fast-moving jets. With blazars, one of those jets points directly at us!
Multimessenger Astronomy is Cool
Today’s announcement combines another pair of messengers. The IceCube Neutrino Observatory lies a mile under the ice in Antarctica and uses the ice itself to detect neutrinos. When IceCube caught a super-high-energy neutrino and traced its origin to a specific area of the sky, they alerted the astronomical community.
Fermi completes a scan of the entire sky about every three hours, monitoring thousands of blazars among all the bright gamma-ray sources it sees. For months it had observed a blazar producing more gamma rays than usual. Flaring is a common characteristic in blazars, so this did not attract special attention. But when the alert from IceCube came through about a neutrino coming from that same patch of sky, and the Fermi data were analyzed, this flare became a big deal!
IceCube, Fermi, and followup observations all link this neutrino to a blazar called TXS 0506+056. This event connects a neutrino to a supermassive black hole for the very first time. Â
Why is this such a big deal? And why haven’t we done it before? Detecting a neutrino is hard since it doesn’t interact easily with matter and can travel unaffected great distances through the universe. Neutrinos are passing through you right now and you can’t even feel a thing!
The neat thing about this discovery — and multimessenger astronomy in general — is how much more we can learn by combining observations. This blazar/neutrino connection, for example, tells us that it was protons being accelerated by the blazar’s jet. Our study of blazars, neutrinos, and other objects and events in the universe will continue with many more exciting multimessenger discoveries to come in the future.

Our Spacecraft Have Discovered a New Magnetic Process in Space
Just as gravity is one key to how things move on Earth, a process called magnetic reconnection is key to how electrically-charged particles speed through space. Now, our Magnetospheric Multiscale mission, or MMS, has discovered magnetic reconnection – a process by which magnetic field lines explosively reconfigure – occurring in a new and surprising way near Earth.
Invisible to the eye, a vast network of magnetic energy and particles surround our planet — a dynamic system that influences our satellites and technology. The more we understand the way those particles move, the more we can protect our spacecraft and astronauts both near Earth and as we explore deeper into the solar system.
Earth’s magnetic field creates a protective bubble that shields us from highly energetic particles that stream in both from the Sun and interstellar space. As this solar wind bathes our planet, Earth’s magnetic field lines get stretched. Like elastic bands, they eventually release energy by snapping and flinging particles in their path to supersonic speeds.
That burst of energy is generated by magnetic reconnection. It’s pervasive throughout the universe — it happens on the Sun, in the space near Earth and even near black holes.
Scientists have observed this phenomenon many times in Earth’s vast magnetic environment, the magnetosphere. Now, a new study of data from our MMS mission caught the process occurring in a new and unexpected region of near-Earth space. For the first time, magnetic reconnection was seen in the magnetosheath — the boundary between our magnetosphere and the solar wind that flows throughout the solar system and one of the most turbulent regions in near-Earth space.
The four identical MMS spacecraft — flying through this region in a tight pyramid formation — saw the event in 3D. The arrows in the data visualization below show the hundreds of observations MMS took to measure the changes in particle motion and the magnetic field.
The data show that this event is unlike the magnetic reconnection we’ve observed before. If we think of these magnetic field lines as elastic bands, the ones in this region are much smaller and stretchier than elsewhere in near-Earth space — meaning that this process accelerates particles 40 times faster than typical magnetic reconnection near Earth. In short, MMS spotted a completely new magnetic process that is much faster than what we’ve seen before.
What’s more, this observation holds clues to what’s happening at smaller spatial scales, where turbulence takes over the process of mixing and accelerating particles. Turbulence in space moves in random ways and creates vortices, much like when you mix milk into coffee. The process by which turbulence energizes particles in space is still a big area of research, and linking this new discovery to turbulence research may give insights into how magnetic energy powers particle jets in space.

A Year on the Sun Through Our Satellite’s Eyes
Did you know we’re watching the Sun 24/7 from space?
We use a whole fleet of satellites to monitor the Sun and its influences on the solar system. One of those is the Solar Dynamics Observatory. It’s been in space for eight years, keeping an eye on the Sun almost every moment of every day. Launched on Feb. 11, 2010, this satellite (also known as SDO) was originally designed for a two-year mission, but it’s still collecting data to this day — and one of our best ways to keep an eye on our star.
To celebrate another year of SDO, we’re sharing some of our favorite solar views that the spacecraft sent back to Earth in 2017.
 March: A long spotless stretch
For 15 days starting on March 7, SDO saw the yolk-like spotless Sun in visible light.
The Sun goes through a natural 11-year cycle of activity marked by two extremes: solar maximum and solar minimum. Sunspots are dark regions of complex magnetic activity on the Sun’s surface, and the number of sunspots at any given time is used as an index of solar activity.
Solar maximum = intense solar activity and more sunspots
Solar minimum = less solar activity and fewer sunspots
This March 2017 period was the longest stretch of spotlessness since the last solar minimum in April 2010 – a sure sign that the solar cycle is marching on toward the next minimum, which scientists expect in 2019-2020. For comparison, the images on the left are from Feb. 2014 – during the last solar maximum –  and show a much spottier Sun.
June: Energized active regions
 A pair of relatively small but frenetic active regions – areas of intense and complex magnetic fields – rotated into SDO’s view May 31 – June 2, while spouting off numerous small flares and sweeping loops of plasma. The dynamic regions were easily the most remarkable areas on the Sun during this 42-hour period.
July: Two weeks in the life of a sunspot
On July 5, SDO watched an active region rotate into view on the Sun. The satellite continued to track the region as it grew and eventually rotated across the Sun and out of view on July 17. Â
With their complex magnetic fields, sunspots are often the source of interesting solar activity: During its 13-day trip across the face of the Sun, the active region — dubbed AR12665 — put on a show for our Sun-watching satellites, producing several solar flares, a coronal mass ejection and a solar energetic particle event.Â
August: An eclipse in space
While millions of people in North America experienced a total solar eclipse on Aug. 21, SDO saw a partial eclipse from space. SDO actually sees several lunar transits a year from its perspective – but an eclipse on the ground doesn’t necessarily mean that SDO will see anything out of the ordinary. Even on Aug. 21, SDO saw only 14 percent of the Sun blocked by the Moon, while most US residents saw 60 percent blockage or more.
September: A spate of solar activity
In September 2017, SDO saw a spate of solar activity, with the Sun emitting 31 notable flares and releasing several powerful coronal mass ejections between Sept. 6-10. Solar flares are powerful bursts of radiation, while coronal mass ejections are massive clouds of solar material and magnetic fields that erupt from the Sun at incredible speeds.
One of the flares imaged by SDO on Sept. 6 was classified as X9.3 – clocking in at the most powerful flare of the current solar cycle. The current cycle began in December 2008 and is now decreasing in intensity, heading toward solar minimum. During solar minimum, such eruptions on the Sun are increasingly rare, but history has shown that they can nonetheless be intense.
September: A trio of tempests
Three distinct solar active regions with towering arches rotated into SDO’s view over a three-day period from Sept. 24-26. Charged particles spinning along the ever-changing magnetic field lines above the active regions trace out the magnetic field in extreme ultraviolet light, a type of light that is typically invisible to our eyes, but is colorized here in gold. To give some sense of scale, the largest arches are many times the size of Earth.
December: A curling prominence
SDO saw a small prominence arch up and send streams of solar material curling back into the Sun over a 30-hour period on Dec. 13-14. Prominences are relatively cool strands of solar material tethered above the Sun’s surface by magnetic fields.
 December: Solar question mark
An elongated coronal hole — the darker area near the center of the Sun’s disk — looked something like a question mark when seen in extreme ultraviolet light by SDO on Dec. 21-22. Coronal holes are magnetically open areas on the Sun that allow high-speed solar wind to gush out into space. They appear as dark areas when seen in certain wavelengths of extreme ultraviolet light.

Going for GOLD
On Jan. 25, we’re going for GOLD!
We’re launching an instrument called Global-scale Observations of the Limb and Disk, GOLD for short. It’s a new mission that will study a complicated — and not yet fully understood — region of near-Earth space, called the ionosphere.
Space is not completely empty: It’s teeming with fast-moving energized particles and electric and magnetic fields that guide their motion. At the boundary between Earth’s atmosphere and space, these particles and fields — the ionosphere — co-exist with the upper reaches of the neutral atmosphere.
That makes this a complicated place. Big events in the lower atmosphere, like hurricanes or tsunamis, can create waves that travel all the way up to that interface to space, changing the wind patterns and causing disruptions.
It’s also affected by space weather. The Sun is a dynamic star, and it releases spurts of energized particles and blasts of solar material carrying electric and magnetic fields that travel out through the solar system. Depending on their direction, these bursts have the potential to disrupt space near Earth.
This combination of factors makes it hard to predict changes in the ionosphere — and that can have a big impact. Communications signals, like radio waves and signals that make our GPS systems work, travel through this region, and sudden changes can distort them or even cut them off completely.
Low-Earth orbiting satellites — including the International Space Station — also fly through the ionosphere, so understanding how it fluctuates is important for protecting these satellites and astronauts. Â
GOLD is a spectrograph, an instrument that breaks light down into its component wavelengths, measuring their intensities. Breaking light up like this helps scientists see the behavior of individual chemical elements — for instance, separating the amount of oxygen versus nitrogen. GOLD sees in far ultraviolet light, a type of light that’s invisible to our eyes.
GOLD is a hosted payload. The instrument is hitching a ride aboard SES-14, a commercial communications satellite built by Airbus for SES Government Solutions, which owns and operates the satellite.
Also launching this year is the Ionospheric Connection Explorer, or ICON, which will also study the ionosphere and neutral upper atmosphere. But while GOLD will fly in geostationary orbit some 22,000 miles above the Western Hemisphere, ICON will fly just 350 miles above Earth, able to gather close up images of this region.
Together, these missions give us an unprecedented look at the ionosphere and upper atmosphere, helping us understand the very nature of how our planet interacts with space.

What Scientists Are Learning from the Eclipse
While millions of people in North America headed outside to watch the eclipse on Aug. 21, 2017, hundreds of scientists got out telescopes, set up instruments, and prepared balloon launches – all so they could study the Sun and its complicated influence on Earth.
Total solar eclipses happen about once every 18 months somewhere in the world, but the August eclipse was rare because of its long path over land. The total eclipse lasted more than 90 minutes over land, from when it first reached Oregon to when it left the U.S. in South Carolina.
This meant that scientists could collect more data from land than during most eclipses, giving us new insight into our world and the star that powers it.
A moment in the Sun’s atmosphere
During a total solar eclipse, the Sun’s outer atmosphere, the corona, is visible from Earth. It’s normally too dim to see next to the Sun’s bright face, but, during an eclipse, the Moon blocks out the Sun, revealing the corona.
Image Credit: Peter Aniol, Miloslav DruckmĂĽller and Shadia Habbal
Though we can study parts of the corona with instruments that create artificial eclipses, some of the innermost regions of the corona are only visible during total solar eclipses. Solar scientists think this part of the corona may hold the secrets to some of our most fundamental questions about the Sun: Like how the solar wind – the constant flow of magnetized material that streams out from the Sun and fills the solar system – is accelerated, and why the corona is so much hotter than the Sun’s surface below. Â
Depending on where you were, someone watching the total solar eclipse on Aug. 21 might have been able to see the Moon completely obscuring the Sun for up to two minutes and 42 seconds. One scientist wanted to stretch that even further – so he used a pair of our WB-57 jets to chase the path of the Moon’s shadow, giving their telescopes an uninterrupted view of the solar corona for just over seven and half minutes.
These telescopes were originally designed to help monitor space shuttle launches, and the eclipse campaign was their first airborne astronomy project!
These scientists weren’t the only ones who had the idea to stretch out their view of the eclipse: The Citizen CATE project (short for Continental-America Telescopic Eclipse) did something similar, but with the help of hundreds of citizen scientists.Â
Citizen CATE included 68 identical small telescopes spread out across the path of totality, operated by citizen and student scientists. As the Moon’s shadow left one telescope, it reached the next one in the lineup, giving scientists a longer look at the way the corona changes throughout the eclipse.
After accounting for clouds, Citizen CATE telescopes were able to collect 82 minutes of images, out of the 93 total minutes that the eclipse was over the US. Their images will help scientists study the dynamics of the inner corona, including fast solar wind flows near the Sun’s north and south poles.
The magnetized solar wind can interact with Earth’s magnetic field, causing auroras, interfering with satellites, and – in extreme cases – even straining our power systems, and all these measurements will help us better understand how the Sun sends this material speeding out into space.
Exploring the Sun-Earth connection
Scientists also used the eclipse as a natural laboratory to explore the Sun’s complicated influence on Earth.
High in Earth’s upper atmosphere, above the ozone layer, the Sun’s intense radiation creates a layer of electrified particles called the ionosphere. This region of the atmosphere reacts to changes from both Earth below and space above. Such changes in the lower atmosphere or space weather can manifest as disruptions in the ionosphere that can interfere with communication and navigation signals.
One group of scientists used the eclipse to test computer models of the ionosphere’s effects on these communications signals. They predicted that radio signals would travel farther during the eclipse because of a drop in the number of energized particles. Their eclipse day data – collected by scientists spread out across the US and by thousands of amateur radio operators – proved that prediction right.
In another experiment, scientists used the Eclipse Ballooning Project to investigate the eclipse’s effects lower in the atmosphere. The project incorporated weather balloon flights from a dozen locations to form a picture of how Earth’s lower atmosphere – the part we interact with and which directly affects our weather – reacted to the eclipse. They found that the planetary boundary layer, the lowest part of Earth’s atmosphere, actually moved closer to Earth during the eclipse, dropped down nearly to its nighttime altitude.
A handful of these balloons also flew cards containing harmless bacteria to explore the potential for contamination of other planets with Earth-born life. Earth’s stratosphere is similar to the surface of Mars, except in one main way: the amount of sunlight. But during the eclipse, the level of sunlight dropped to something closer to what you’d expect to see on Mars, making this the perfect testbed to explore whether Earth microbes could hitch a ride to the Red Planet and survive. Scientists are working through the data collected, hoping to build up better information to help robotic and human explorers alike avoid carrying bacterial hitchhikers to Mars.

Finally, our EPIC instrument aboard NOAA’s DSCOVR satellite provided awe-inspiring views of the eclipse, but it’s also helping scientists understand Earth’s energy balance. Earth’s energy system is in a constant dance to maintain a balance between incoming radiation from the Sun and outgoing radiation from Earth to space, which scientists call the Earth’s energy budget. The role of clouds, both thick and thin, is important in their effect on energy balance.
Like a giant cloud, the Moon during the total solar eclipse cast a large shadow across a swath of the United States. Scientists know the dimensions and light-blocking properties of the Moon, so they used ground- and space-based instruments to learn how this large shadow affects the amount of sunlight reaching Earth’s surface, especially around the edges of the shadow. Measurements from EPIC show a 10% drop in light reflected from Earth during the eclipse (compared to about 1% on a normal day). That number will help scientists model how clouds radiate the Sun’s energy – which drives our planet’s ocean currents, seasons, weather and climate – away from our planet.

Why We Study the Sun-Earth Connection – Explained Through Songs
We're launching a new mission to the International Space Station to continue measurements of the Sun's energy reaching Earth.
The Total and Spectral solar Irradiance Sensor (TSIS-1) will precisely measure the total amount of sunlight that falls on Earth and how that light is distributed among different wavelengths, including the ultraviolet, visible and infrared. This will give us a better understanding of Earth’s primary energy supply and help improve models simulating Earth’s climate.
1. You are my sunshine, my only sunshine. You make me happy when skies are gray.
The Sun is Earth's sunshine and it does more than make us happy; it gives us life. Our Sun's energy drives our planet's ocean currents, seasons, weather and climate. Changes in the Sun also alter our climate in at least two ways.
First, solar radiation has a direct effect where it heats regions of Earth, like our oceans, land, and atmosphere. Second, the solar radiation can cause indirect effects, such as when sunlight interacts with molecules in the upper atmosphere to produce ozone which can affect human health. Â
Earth’s energy system is in a constant dance to maintain a balance between incoming energy from the Sun and outgoing energy from Earth to space, which scientists call Earth’s energy budget. If you have more energy absorbed by the Earth than leaving it, its temperature increases and vice versa. Because the Sun is Earth's fundamental energy source and only sunshine, we need a quantitative record of the Sun's solar energy output. TSIS-1 will provide the most accurate measurements ever made of sunlight as seen from above Earth’s atmosphere.
2. You're hot then you're cold…You're in then you're out. You're up then you're down.
The energy flow between the Earth and Sun's connection is not a constant thing. The Sun can be fickle, sometimes it puts out slightly more energy and some years less. Earth is no better. The Earth absorbs different amounts of the Sun's energy depending on many factors, such as the presence of clouds and tiny particles in the atmosphere called aerosols. Â
What we do know is that the Sun's cycle is about 11 years rolling through periods of quiet to times of intense activity. When the Sun is super-intense it releases explosions of light and solar material. This time is a solar maximum.
When the Sun is in a quiet state this period is called the solar minimum.
Over the course of one solar cycle (one 11-year period), the Sun’s total emitted energy varies on average at about 0.1 percent. That may not sound like a lot, but the Sun emits a large amount of energy – 1,361 watts per square meter. Even fluctuations at just a tenth of a percent can affect Earth. That's why TSIS-1 is launching: to help scientists understand and anticipate how changes in the Sun will affect us on Earth.
3. You're so vain. You probably think this climate model is about you.
Scientists use computer models to interpret changes in the Sun’s energy input. If less solar energy is available, scientists can gauge how that affects Earth’s atmosphere, oceans, weather and seasons by using computer simulations. But the Sun is just one of many factors scientists use to model Earth’s climate. A lot of other factors come into play in addition to the energy from the Sun. Factors like greenhouse gases, clouds scattering light and small particles in the atmosphere called aerosols all can affect Earth’s climate so they all need to be included in climate models. So, while we need to measure the total amount of energy from the Sun, we also need to understand how these other factors alter the amount of energy reaching Earth's surface and affect our climate.
4. Someday we'll find it, the rainbow connection. The lovers, the dreamers and me.
We receive the Sun's energy in many different wavelengths, including visible light (rainbows!) as well as light we can't see like infrared and ultraviolet wavelengths. Each color or wavelength of light from the Sun affects Earth’s atmosphere differently.
For instance, ultraviolet light from the Sun can affect Earth's ozone. High in the atmosphere is a layer of protective ozone gas. Ozone is Earth’s natural sunscreen, absorbing the Sun’s most harmful ultraviolet radiation and protecting living things below. But ozone is vulnerable to certain gases made by humans that reach the upper atmosphere. Once there, they react in the presence of sunlight to destroy ozone molecules. Currently, several satellites from us and the National Oceanic and Atmospheric Administration (NOAA) track the ozone in the upper atmosphere and the solar energy that drives the photochemistry that creates and destroys ozone. Our new instrument, TSIS-1, will join that fleet with even better accuracy.
TSIS-1 will see different types of ultraviolet (UV) light, including UV-B and UV-C. Each plays a different role in the ozone layer. UV-C rays are essential in creating ozone. UV-B rays and some naturally occurring chemicals regulate the abundance of ozone in the upper atmosphere. The amount of ozone is a balance between these natural production and loss processes.
TSIS-1 data of the Sun's UV energy will help improve computer models of the atmosphere that need accurate measurements of sunlight across the ultraviolet spectrum to model the ozone layer correctly. While UV light represents a tiny fraction of the total sunlight that reaches the top of Earth's atmosphere, it fluctuates from 3 to 10 percent, a change that, in turn causes small changes in the chemical composition and thermal structure of the upper atmosphere.
This is just one of the important applications of TSIS-1 measurements. TSIS-1 will measure how the Sun's energy is distributed over 1,000 different wavelengths.
5. Every move you make…every step you take, I'll be watching you.
TSIS-1 will continue our nearly 40 years of closely studying the total amount of energy the Sun sends to Earth from space. We've previously studied this 'total solar irradiance' with nine previous satellites, currently with Solar Radiation and Climate Experiment, (SORCE).
NASA’s SORCE collected this data on the total amount of the Sun’s radiant energy throughout Sept. 2017. The satellite actually detected a dip in total irradiance – or the total amount of energy from the Sun- during the month’s intense solar activity.
But there's still very much we don't know about total solar irradiance. We do not know how it varies over longer timescales. Longer term observations are especially important because scientists have observed unusually quiet magnetic activity from the Sun for the past two decades with previous satellites. During the last prolonged solar minimum in 2008-2009, our Sun was the quietest it has ever been since we started observations in 1978. Scientists expect the Sun to enter a solar minimum within the next three years, and TSIS-1 will be primed to take measurements of the next minimum and see if this is part of a larger trend.

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by our Solar Dynamics Observatory on April 24-26, 2017.Â
These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in this wavelength of extreme ultraviolet light. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold.Â
