Astronomers from the University of Hawai'i (UH) at Manoa and elsewhere have observed the Taurus star-forming region, which ...

A classical nova may look simple at first. A faint star brightens, sometimes enough for you to spot without a telescope, then slowly dims over weeks or months. Behind that short burst of light sits a ...

A Texas Tech Assistant Astronomy Professor, Elias Aydi, along with other astronomers, used a cutting-edge technique to ...

Subtle variations in the star’s brightness suggest it once collided and merged with another star, an explosive event that left it spinning rapidly. It now orbits a quiet black hole in the Gaia BH2 ...

They’re bright and blue — and a bit strange. They’re a new type of stellar explosion that was recently discovered by a team of astronomers led by the California Institute of Technology (Caltech).

A red dwarf 130 light-years away has just rewritten the rules of space weather. For the first time, astronomers have captured definitive evidence of a massive coronal mass ejection from a star other ...

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 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 ...
