The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks ...

Astronomers directly imaged a faint companion star orbiting Betelgeuse, solving a decades-old mystery about its strange ...

Astronomers have captured a first-of-its-kind image of a massive dying star.

Scientists have captured the moment the shockwave of a supernova explosion breaks out through the surface of a doomed star ...

When this shock reaches the surface, it releases an enormous burst of energy. The star brightens dramatically, becoming visible as a supernova. For a short period, astronomers can study the initial ...

Scientists now have observed for the first time the very early stages of a supernova, with a massive star exploding in a ...

A University of Hawaiʻi Mānoa astronomer helped pull off a cosmic first: mapping the three‑dimensional shape of a star’s ...

Swift observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the explosive ...

Panels A-D (clockwise from upper left) show several different stages of the supernova: the location of the host galaxy after the supernova faded, the three images of the host galaxy and the supernova ...

Data from NASA's Hubble Space Telescope shows that bright red supergiant star Betelgeuse "blew its top" in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass ...
