Milky Way

Gaia BH3 is the largest-known stellar black hole, according to astronomer and study co-author Tsevi Mazeh of the Tel Aviv University in Israel.

Black holes are extraordinarily dense objects with gravity so strong that not even light can escape, making viewing them extremely challenging.

Getting in the Super Bowl spirit? Sagittarius A*, the supermassive black hole at the heart of our galaxy, spins so fast that it makes spacetime around it shaped like a football.

The new mapping method may allow astronomers to study previously obscured parts of the galaxy and of the universe.

Over the years, astronomers have classified galaxies into three main shapes: elliptical, irregular and spiral.

Humanity has been looking for aliens for decades but has yet to find any evidence. A new study suggests we may just be in a sort of cosmic blind spot for alien radio signals.

Quasar galaxy 3C 297 is all alone in space, but from what we know, it should be within a galaxy cluster. How did this happen? It seemingly ate all of them.

This discovery could completely upend our understanding of space, with the paper's co-author describing the entire situation as "bananas."

Not all supernovas will have the same impact on the solar system.

Only a millionth of simulated galaxies were located in a cosmological wall like the Local Sheet and had a mass like the Milky Way's.
