Supernova

For the first time, scientists have detected radio waves from a Type Ibn supernova, revealing the final years of a massive star's life. The signals show the star shed significant material just before exploding, likely due to a companion star. This discovery offers a new method to study stellar deaths using radio telescopes.

Astronomers have observed a massive star in the nearby Andromeda galaxy that appears to have disappeared without exploding, potentially forming a black hole in a failed supernova. Recent telescope observations reveal a faint remnant shrouded in dust, though alternative explanations like a stellar merger remain possible. This rare event highlights new insights into the fates of massive stars.
