About 15 years ago, our Hubble Space Telescope captured this ultra-deep field image of space, revealing thousands of galaxies tucked away in a seemingly empty spot in the sky.
Now, imagine this view of the cosmos – and all the mysteries in it – at a scale 300 times larger than Hubble's.
Our upcoming Nancy Grace Roman Telescope could capture just that.
Roman recently released this gorgeous simulated image that gives us a preview of what the telescope could see. Each tiny speck represents a galaxy filled with billions of stars. And it’s more than just a pretty picture – scientists could learn a lot from an observation like this!
Since Roman can see much more of the sky at a time, it could create an ultra-deep field image that’s far larger than Hubble’s. So instead of revealing thousands of galaxies, Roman would see millions!
Roman’s ability to look far out into space with such an expansive view would help us better understand what the universe was like when it was young. For example, scientists could study a lot of cosmic transitions, like how galaxies switch from star-making factories to a quieter stage when star formation is complete and how the universe went from being mainly opaque to the brilliant starscape we see today.
And these are just a few of the mysteries Roman could help us solve!
Set to launch in the mid-2020s, our Nancy Grace Roman Space Telescope, is designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics. You can learn about some of the other science Roman will do here.

- Ellen Ochoa is the first Hispanic director of NASA’s Johnson Space Center and the first Hispanic woman to go to space.
Q: You were the first Hispanic woman to go to space, and you’re the first Hispanic director of the Johnson Space Center. What does the achievement of firsts like these mean to you? What kind of responsibility comes with paving the way?
Becoming an astronaut was a personal goal for me, so I was surprised and overwhelmed to receive such warm support from the entire Hispanic community when I was selected for the astronaut corps. I realized, really for the first time, that people who didn’t even know me were wishing for my success — hoping to share in the pride of future accomplishments, but even more important, willing to provide encouragement in the face of disappointments. In the same way, in addition to working hard to do my best at every position I’ve had, it became an important part of my job to provide encouragement to others, particularly women and minorities underrepresented in STEM [Science Technology Engineering and Math] fields. I hope that by sharing my experiences, others will be inspired to set high goals for themselves.
Q: Have you experienced any particular challenges as a female astronaut? How have you stayed motivated in the face of such challenges?
Actually, the women astronauts who came before me performed their jobs so well that it really wasn’t an issue. There was probably more skepticism due to my research background, given that the job is an operational one, and I didn’t have much experience in that environment. The training we’re provided helped prepare me well, as did veterans astronauts who passed on helpful tips.
Q: As a pioneer of spacecraft technology and a champion of outreach, how do you think we can inspire more women to enter STEM fields?
Use every available communications avenue to let women know about the interesting and rewarding careers in the STEM fields. The website Women@NASA profiles many women around the agency, having them describe in their own words what they do and the path that led them to their careers. And since girls start making choices in middle school that can limit their options later on, there’s a section on the website aimed specifically at middle school girls called Aspire to Inspire featuring women at Johnson Space Center. NASA has also made great use of many social media platforms to spread the word on what we are doing in space exploration, both human and robotics. From the first flyby of Pluto to the completion of a one-year mission onboard the International Space Station, this has been an exciting year for NASA.
Exactly sixty years ago today, we opened our doors for the first time. And since then, we have opened up a universe of discovery and innovation.
There are so many achievements to celebrate from the past six decades, there’s no way we can go through all of them. If you want to dive deeper into our history of exploration, check out NASA: 60 Years and Counting.
In the meantime, take a moonwalk down memory lane with us while we remember a few of our most important accomplishments from the past sixty years!
In 1958, President Eisenhower signed the National Aeronautics and Space Act, which effectively created our agency. We officially opened for business on October 1.
To learn more about the start of our space program, watch our video: How It All Began.
Alongside the U.S. Air Force, we implemented the X-15 hypersonic aircraft during the 1950s and 1960s to improve aircraft and spacecraft.
The X-15 is capable of speeds exceeding Mach 6 (4,500 mph) at altitudes of 67 miles, reaching the very edge of space.
Dubbed the “finest and most productive research aircraft ever seen,” the X-15 was officially retired on October 24, 1968. The information collected by the X-15 contributed to the development of the Mercury, Gemini, Apollo, and Space Shuttle programs.
To learn more about how we have revolutionized aeronautics, watch our Leading Edge of Flight video.
On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first humans to walk on the moon. The crew of Apollo 11 had the distinction of completing the first return of soil and rock samples from beyond Earth.
Astronaut Gene Cernan, during Apollo 17, was the last person to have walked on the surface of the moon. (For now!)
The Lunar Roving Vehicle was a battery-powered rover that the astronauts used during the last three Apollo missions.
To learn more about other types of technology that we have either invented or improved, watch our video: Trailblazing Technology.
Our long-term Earth-observing satellite program began on July 23, 1972 with the launch of Landsat 1, the first in a long series (Landsat 9 is expected to launch in 2020!) We work directly with the U.S. Geological Survey to use Landsat to monitor and manage resources such as food, water, and forests.
Landsat data is one of many tools that help us observe in immense detail how our planet is changing. From algae blooms to melting glaciers to hurricane flooding, Landsat is there to help us understand our own planet better.
Off the Earth, for the Earth.
To learn more about how we contribute to the Earth sciences, watch our video: Home, Sweet Home.
Space Transportation System-1, or STS-1, was the first orbital spaceflight of our Space Shuttle program.
The first orbiter, Columbia, launched on April 12, 1981. Over the next thirty years, Challenger, Discovery, Atlantis, and Endeavour would be added to the space shuttle fleet.
Together, they flew 135 missions and carried 355 people into space using the first reusable spacecraft.
On January 16, 1978, we selected a class of 35 new astronauts--including the first women and African-American astronauts.
And on June 18, 1983, Sally Ride became the first American woman to enter space on board Challenger for STS-7.
To learn more about our astronauts, then and now, watch our Humans in Space video.
Everybody loves Hubble! The Hubble Space Telescope was launched into orbit on April 24, 1990, and has been blowing our minds ever since.
Hubble has not only captured stunning views of our distant stars and galaxies, but has also been there for once-in-a-lifetime cosmic events. For example, on January 6, 2010, Hubble captured what appeared to be a head-on collision between two asteroids--something no one has ever seen before.
In this image, Hubble captures the Carina Nebula illuminating a three-light-year tall pillar of gas and dust.
To learn more about how we have contributed to our understanding of the solar system and beyond, watch our video: What’s Out There?
Cooperation to build the International Space Station began in 1993 between the United States, Russia, Japan, and Canada.
The dream was fully realized on November 2, 2000, when Expedition 1 crew members boarded the station, signifying humanity’s permanent presence in space!
Although the orbiting lab was only a couple of modules then, it has grown tremendously since then!
To learn more about what’s happening on the orbiting outpost today, visit the Space Station page.
We have satellites in the sky, humans in orbit, and rovers on Mars. Very soon, we will be returning humankind to the Moon, and using it as a platform to travel to Mars and beyond.
And most importantly, we bring the universe to you.

One hundred years ago a total solar eclipse turned an obscure scientist into a household name. You might have heard of him — his name is Albert Einstein. But how did a solar eclipse propel him to fame?
First, it would be good to know a couple things about general relativity. (Wait, don’t go! We’ll keep this to the basics!)
A decade before he finished general relativity, Einstein published his special theory of relativity, which demonstrates how space and time are interwoven as a single structure he dubbed “space-time.” General relativity extended the foundation of special relativity to include gravity. Einstein realized that gravitational fields can be understood as bends and curves in space-time that affect the motions of objects including stars, planets — and even light.
For everyday situations the centuries-old description of gravity by Isaac Newton does just fine. However, general relativity must be accounted for when we study places with strong gravity, like black holes or neutron stars, or when we need very precise measurements, like pinpointing a position on Earth to within a few feet. That makes it hard to test!
A prediction of general relativity is that light passing by an object feels a slight "tug", causing the light's path to bend slightly. The more mass the object has, the more the light will be deflected. This sets up one of the tests that Einstein suggested — measuring how starlight bends around the Sun, the strongest source of gravity in our neighborhood. Starlight that passes near the edge of the Sun on its way to Earth is deflected, altering by a small amount where those stars appear to be. How much? By about the width of a dime if you saw it at a mile and a quarter away! But how can you observe faint stars near the brilliant Sun? During a total solar eclipse!
That’s where the May 29, 1919, total solar eclipse comes in. Two teams were dispatched to locations in the path of totality — the places on Earth where the Moon will appear to completely cover the face of the Sun during an eclipse. One team went to South America and another to Africa.
On eclipse day, the sky vexed both teams, with rain in Africa and clouds in South America. The teams had only mere minutes of totality during which to take their photographs, or they would lose the opportunity until the next total solar eclipse in 1921! However, the weather cleared at both sites long enough for the teams to take images of the stars during totality.
The teams took two sets of photographs of the same patch of sky – one set during the eclipse and another set a few months before or after, when the Sun was out of the way. By comparing these two sets of photographs, researchers could see if the apparent star positions changed as predicted by Einstein. This is shown with the effect exaggerated in the image above.
A few months after the eclipse, when the teams sorted out their measurements, the results demonstrated that general relativity correctly predicted the positions of the stars. Newspapers across the globe announced that the controversial theory was proven (even though that’s not quite how science works). It was this success that propelled Einstein into the public eye.
The solar eclipse wasn’t the first test of general relativity. For more than two centuries, astronomers had known that Mercury’s orbit was a little off. Its perihelion — the point during its orbit when it is closest to the Sun — was changing faster than Newton’s laws predicted. General relativity easily explains it, though, because Mercury is so close to the Sun that its orbit is affected by the Sun’s dent in space-time, causing the discrepancy.
In fact, we still test general relativity today under different conditions and in different situations to see whether or not it holds up. So far, it has passed every test we’ve thrown at it.
Curious to know where we need general relativity to understand objects in space? Tune into our Tumblr tomorrow to find out!

Asteroids are the storytellers of our solar system’s youth. They are the closest we can get to the original material that makes up the sun, planets, and moons.
This week, our OSIRIS-REx spacecraft made history when it touched a pristine, ancient asteroid named Bennu to collect a sample from the surface. The intrepid spacecraft will now bring the asteroid sample – and its stories – back home to Earth.
Why is it that asteroid Bennu holds the history of our origins? Let’s go back to the beginning...
About 4.5 billion years ago, our solar system began as a spinning, swirling cloud made up of tiny bits of gaseous and rocky material. Most of that material – more than 99% of it – gathered in the center and went on to become the Sun.
The leftovers began to spin around the Sun, colliding into one another and forming larger and larger objects, eventually becoming planets, dwarf planets, and moons.
But asteroids didn't become part of planets or moons. So, while the material in planets and moons were superheated and altered during the formation of the solar system and weathered by geologic processes over time, asteroids remained pristine.
Each asteroid holds knowledge from that special time in our solar system’s history. Each one contains information about the chemicals, minerals, and molecules that were present when the solar system was just starting to form.
With missions like OSIRIS-REx, we are going on a journey to these ancient worlds, seeking to learn what they remember, seeking to expand our knowledge, and deepen our understanding of our origins.

in a male dominated profession, what were some obstacles you faced as the first Hispanic female flight director and how did you overcome them? what would be your advice to young women interested in the space program?
Freaky fast and really awesome! NASA astronaut Jack Fischer posted this GIF to his social media Tuesday saying, “I was checking the view out the back window & decided to take a pic so you can see proof of our ludicrous speed! #SpaceIsAwesome”.
In case you didn’t know, the International Space Station travels 17,500 miles per hour as it orbits 250 miles above the Earth.
Currently, three humans are living and working there, conducting important science and research. The orbiting laboratory is home to more than 250 experiments, including some that are helping us determine the effects of microgravity on the human body. Research on the station will not only help us send humans deeper into space than ever before, including to Mars, but also benefits life here on Earth.
