In an unprecedented discovery, astronomers have observed a new type of supernova that seems to defy the very principles of stellar evolution that have been held for decades. The supernova, named ...

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

A new discovery about what happens when a supernova – an exploding star – and a black hole collide could change the way scientists understand the lives and deaths of stars. The finding was the first ...

An international team of astronomers reports the discovery of a new supernova remnant that showcases a remarkable circular symmetry in shape. The detection of the remnant, dubbed "Teleios," is ...
