Stellar astronomy and planetary systems form a cornerstone of astrophysical research, uniting our understanding of the life cycles of stars with the intricate architecture of the systems that form ...

Astronomers are rethinking what looks like the Milky Way’s quieter neighborhood, as new analysis of nearby gas clouds points ...

One of astronomy’s fundamental concepts is that Earth orbits an average star, which coasts through a non­descript portion of our Milky Way, a typical spiral galaxy. It’s a notion that harks back to ...

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

A Chinese research team has developed an artificial intelligence (AI) model called SpecCLIP, which can interpret stellar spectral data from different telescopes, demonstrating the vast potential of AI ...

Astronomers using NASA’s Chandra X-ray Observatory have clocked the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. This result has important implications for ...

Astronomers have confirmed the existence of a companion star in a tight orbit around Betelgeuse, resolving a long-standing mystery about the star’s varying brightness. A 600-year-old stellar event ...

Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.

Plans are underway to add a seventh movable telescope to Georgia State University’s Center for High Angular Resolution Astronomy— known as the CHARA Array—that would increase the resolution, or the ...

Mira A is in the late stages of its life, a red giant swelling and losing mass as it prepares to fade into a white dwarf. While stars of this type routinely shed material, the sheer scale and symmetry ...

Eliza Frankel, a University of Wyoming physics and astronomy Ph.D. student, poses with her award-winning poster at a meeting of the American Astronomical Society in Phoenix, Ariz. in early January.
