Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known ...

Learn how galactic archaeology uses chemical clues to uncover how galaxies formed and evolved over billions of years.

A new study has found that a hidden bias in galaxy models can skew gravitational-wave measurements of how fast the universe is expanding. That finding complicates one of astronomy’s most promising ...

A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic ...

(CN) — A nearby galaxy may be falling apart, and its larger neighbor could be the reason why. Astronomers studying the Small Magellanic Cloud — a dwarf galaxy about 200,000 light-years from Earth — ...

The latest data release from the Sloan Digital Sky Survey (SDSS) includes observations revealing the internal structure and composition of nearly 5,000 nearby galaxies observed during the first three ...

At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history.

By reading the chemical “fingerprints” of a distant galaxy, astronomers reconstructed its 12-billion-year evolution. This new ...

Astronomers using the James Webb Space Telescope have identified emerging young star clusters still breaking free from their ...
