A large international team of astronomers and astrophysicists has discovered something new in the night sky—a type of explosion that is much brighter than most supernovae and is called luminous fast cooler (LFC). In their ...
NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense ...

A team of astronomers from the University of Washington, the SETI Institute, Yale University and Smith College is searching the vicinity of a new supernova in the spiral arms of the Pinwheel Galaxy hoping to find a signal ...
The bright, red star Betelgeuse in the constellation Orion has shown some unexpected behavior. In late 2019 and 2020 it became fainter than we had ever seen it—at least in records going back more than a century. Briefly ...

Whenever something happens with Betelgeuse, speculations about it exploding as a supernova proliferate. It would be cool if it did. We're far enough away to suffer no consequences, so it's fun to imagine the sky lighting ...

When stars like our sun die, they tend to go out with a whimper and not a bang—unless they happen to be part of a binary (two) star system that could give rise to a supernova explosion.
