The spiral arms of nearby galaxy Messier 81 is captured by NASA's Spitzer Space Telescope. This galaxy is easily visible ...

That's equivalent to lining up 140 Milky Way galaxies back to ... Sep. 18, 2024 — Astronomers examined galaxy Arp 107 which has revealed a wealth of information about star-formation and how two ...

This new Webb image shows two galaxies: a Penguin (NGC 2936) guarding an Egg (NGC 2937). Webb’s observations reveal the two are in a cosmic hug, joined together by a blue haze of stars and gas.

What appears to be a mama bird guarding her brightly glowing hatchling is actually a pair of distant galaxies collectively known as Arp 142 — also called "the Penguin" and "the Egg," for reasons ...

It’s bizarre and awesome, and its existence tells the story of a colossal collision between two galaxies a long ... more The galaxy system is labeled Arp-Madore 2026-424, but what it lacks ...

Going across a galaxy or to more distant galaxies would take years and many lifetimes. So, if you want to be a space-faring species, you must travel faster than light (FTL). How would you do that?

With highly capable instruments James Webb Space Telescope (JWST) was able to capture the image of a distant galaxy. Arp 107: ...

The galaxy's distinctive shape is created by a ring-like formation of gas and star activity surrounding it. The barred spiral galaxy gets its shape from a supernova, or a star's explosive death ...

These are just a taste of the discoveries made by the $10 billion Webb telescope since it began science observations in 2022.

IC 1101 is one of the largest galaxies we know of, found in a galaxy cluster called Abell 2029. It spans about 6 million light-years and contains around two trillion stars.

So what happened to IC 3225? A galaxy may be an island of stars, but they don't exist alone; galaxies are almost always found in groups, which can contain thousands of "islands" held together by ...
