Milky Way billions of years ago. This remarkable journey, revealed through the most detailed catalog of similar stars to date ...

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 ...

Researchers have uncovered evidence for our sun joining a mass migration of similar "twins" leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an ...

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 ...

New high-resolution simulations reveal that stellar rotation plays a crucial role in transporting material inside red giant stars.

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 ...

Astronomers present an explanation for the mesmerising shapes of planetary nebulae. The discovery is based on an extraordinary set of observations of stellar winds around ageing stars. Contrary to ...

A mass migration of stellar twins. Stars similar to our Sun form a mass migration from the center of the Milky Way Galaxy, occurring approximately 4 ...

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.

Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.
