For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

The Milky Way has just been reconstructed in unprecedented detail, with artificial intelligence helping astronomers track the motions and histories of roughly 100 billion stars inside a single digital ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

Scientists in China have developed an AI model that analyzes stellar data from different telescopes, helping astronomers combine survey data.

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.

Astronomers in Leiden have used the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile to produce a new ...

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the universe seems to be expanding faster than expected, throwing a wrench into ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

The theory explains the violent dance of stars around the galactic center.
