Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova ...

Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the narratives and artworks of Indigenous cultures, these cosmic spectacles ...

Supernova destroying planet, illustration. A rocky planet lies in the wake of its star, which has just gone supernova. The explosion shatters the planet. A complete census of massive stars in our part ...

When a star in the nearby galaxy NGC 2146 exploded in late 2024, it barely registered by supernova standards. The blast, cataloged as SN 2024abfl, was roughly 100 times fainter than a typical stellar ...
