Supernovas are a celestial double-edged sword: they represent the violent death of a star and pose an immediate threat to anything within cosmic striking distance. But they also create a chemical ...

Astronomers from the University of Massachusetts and Columbia University have found the “bulls-eye” pulsar in a bright ring of high-energy particles in a distant supernova remnant. This discovery, ...

A new star explosion, called a nova, has flared up in the night sky, and it is fairly easy to spot with binoculars — and potentially even the naked eye — by stargazers with clear weather and dark ...
