A recent study of supernova SN 2024bch challenges traditional understanding of stellar deaths and supernovas, suggesting a different energy mechanism called Bowen fluorescence.

An unexpected deep-sea deposit may be the smoking gun from a nearby star that exploded as a supernova in the relatively ...

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...

When the two stars eventually smash into each other, the supernova explosion would be visible from Earth, even during daytime.

In November 1572, a brilliant new star appeared in the constellation Cassiopeia, shining so brightly that it was visible ...
