A classical nova may look simple at first. A faint star brightens, sometimes enough for you to spot without a telescope, then ...

Astronomers have captured images of two stellar explosions—known as novae—within days of their eruption and in unprecedented ...

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

Astronomers have uncovered clues to a red giant’s chaotic past by detecting subtle stellar vibrations that hint at a long-ago collision and an unexpectedly rapid spin. Astronomers at the (IfA) have pi ...

Previously, the most ancient supernova ever confirmed dated back to when the universe was 1.8 billion years old.

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).

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 ...
