An unusual star system created more of a fizz and less of a bang when it exploded in a supernova. The “ultra-stripped” supernova led researchers to discover the two stars 11,000 light-years ...

What’s unique about this new supernova, called SN 2018zd, is that astronomers were able to compare Hubble and Spitzer space telescope images of its host galaxy before and after the explosion.

The supernova, named SN 2023ixf, is located 21 million light-years away. It should remain visible with the aid of a telescope for at least a few months, astronomers said.

Pictures of a distant supernova remnant show two concentric rings, providing clear evidence that exploding white dwarf stars ...
