The largest known star in the universe, compared to Earth.
In order of appearance - Earth, Sol (Our Sun), Sirius, Betelgeuse, Canis Majoris.
Canis Majoris is in fact so large, that if it were to replace our own sun the star itself would extend outwards past the orbit of Jupiter.

NASA’s Webb Space Telescope Reveals Astounding, Unprecedented Views of the Universe
Imagine how long it would take to eat a candy cane that’s a thousand trillion miles tall! 😋
Scientists peering into the center of our Milky Way galaxy found this 190-light-year tall “candy cane,” but (sadly) it is not a peppermint treat. It does contain other goodies, though. They have found huge collections of material, called giant molecular clouds, where stars are being born. And there are magnetic fields that might be evidence of a bubble from an outburst in our galactic center long ago.
The full image shows our galaxy’s center in infrared (blue), radio (red) and microwave (“minty” green) light. The picture essentially color codes different ways light is produced. The blue and cyan regions show us cool dust where star formation has just begun. Yellow features show more-established star “factories.” Red reveals places where electrically charged gas interacts with magnetic fields.
This image includes newly published observations using an instrument designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, called the Goddard-IRAM Superconducting 2-Millimeter Observer (GISMO). It was used with a 30-meter radio telescope located on Pico Veleta, Spain, operated by the Institute for Radio Astronomy in the Millimeter Range headquartered in Grenoble, France. The image shows a region about 750 light-years wide.

Modern geometric illustrations of Planets of the Solar System. These infographic illustrations feature a history of scientific exploration. Probes, satellites, space stations, etc., highlighting the achievements of man in astronomic discovery. Each illustration also features the distance from the Sun, rotational period in days/years and the number of confirmed, natural satellites.

“ ...The lingering airglow is due to chemiluminescence, the production of light through chemical excitation. Originating at an altitude similar to aurora, it can found around the globe. The chemical energy is initially provided by the Sun's extreme ultraviolet radiation.” X

The Perseid meteor shower, one of the biggest meteor showers of the year, will be at its brightest early in the morning on Wednesday, August 12. Read on for some tips on how to watch the night sky this week – and to find out: what exactly are the Perseids, anyway?

Your best chance to spot the Perseids will be between 2 AM and dawn (local time) the morning of August 12. Find a dark spot, avoid bright lights (yes, that includes your phone) and get acclimated to the night sky.
Your eyes should be at peak viewing capacity after about 30 minutes; though the Moon may block out some of the dimmer meteors, you should still be able to see up to 15-20 an hour. If you’re not an early bird, you can try and take a look soon after sunset (around 9 PM) on the 11th, though you may not see as many Perseids then.

If it’s too cloudy, or too bright, to go skywatching where you are, you can try again Wednesday or Thursday night – or just stay indoors and watch the Perseids online!
Our Meteor Watch program will be livestreaming the Perseids from Huntsville, Alabama on Facebook (weather permitting), starting around 9 p.m. EDT on August 11 and continuing through sunrise.
Because all of a meteor shower’s meteors have similar orbits, they appear to come from the same place in the sky – a point called the radiant.
The radiant for the Perseids, as you might guess from the name, is in the constellation Perseus, found near Aries and Taurus in the night sky.

Right! The Perseids are actually fragments of the comet Swift-Tuttle, which orbits within our solar system.
