A new preprint study has taken a closer look at the "universe-breaking" Little Red Dot galaxies discovered in the early ...

"And so their estimates put us at, like, 200 billion, maybe even 100 billion galaxies in the visible universe. "So somewhere between 2 trillion galaxies at the top edge and 100 billion at the ...

Computer algorithms can model the universe, matching simulations to observations and revealing the distribution of dark ...

A hundred years ago, astronomer Edwin Hubble dramatically expanded the size of the known universe. At a meeting of the ...

The Milky Way has two prominent satellite galaxies, called the Large and Small Magellanic Clouds. (The Magellanic Clouds are visible on Earth only from the southern hemisphere; their existence was ...

The visible universe—including Earth, the sun, other stars, and galaxies—is made of protons, neutrons, and electrons bundled together into atoms. Perhaps one of the most surprising discoveries ...

Andromeda being in the same Local Group as the Milky Way (the farthest object visible to the naked eye). Go farther out — using telescopes — and it's possible to see things like galaxies M81 ...

This rare quasar with spiral arms could help astronomers understand how supermassive black holes feed and grow.

A visible arc created by gravitational lensing ... In the Milky Way and nearby galaxies, such as the Andromeda Galaxy, astronomers can observe stars one by one. But for galaxies billions of ...

"This discovery poses a challenge to the Lambda Cold Dark Matter model, which may struggle to account for the formation of such small, aligned groups of galaxies in isolated environments.
