Astronomers have their eyes on a new ultrabright explosion in space: a Type II supernova in the Pinwheel Galaxy (also known as M101). A Type II supernova is the catastrophic end to a massive star's ...

Meteorites can act as time capsules, preserving molecules from the solar system’s infancy. Certain fingerprints have been detected in these ancient space rocks that suggest a supernova went off right ...

The James Webb Space Telescope has captured some bizarre imagery of an exploding star that, for some reason, kept repeating itself. In a press release, NASA said that new Webb images of what ...

An international team of astronomers has performed photometric and spectroscopic observations of a distant Type Ibn supernova known as SN 2024acyl. Results of the observational campaign, published ...

A long-predicted type of cosmic explosion has finally burst onto the scene. Researchers have found convincing evidence for an electron-capture supernova, a stellar explosion ignited when atomic nuclei ...

Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form. These massive stars, located ...

When one supernova commenced, it looked like an olive — at least before it got shaken and stirred. This insight, reported in the Nov. 12 Science Advances, comes from new observations taken in the wake ...

Type Ia supernovae result from a white dwarf exceeding 1.4 solar masses after accreting hydrogen from a companion star, leading to a thermonuclear explosion. The Sirius system contains a white dwarf ...

Kepler's Supernova (CTB 41), the last naked-eye visible supernova in our galaxy, was first observed in October 1604 by Lodovico delle Colombe, reaching a magnitude of -2.5. Johannes Kepler, though not ...
