Supernova

Astronomers have identified a bright supernova from over 10 billion years ago, its light gravitationally lensed into multiple images by a foreground galaxy. This unique observation allows simultaneous views of different stages of the explosion. The time delays between images could reveal details about the universe's expansion rate and dark energy.

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.
