Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

Supernovae are colossal explosions triggered as ancient stars come to the end of their lives. Scientists have done huge amounts of work to identify and understand these cosmic fireworks but, in the ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

Oscillations in the brightness of a ‘superluminous’ supernova reveal it to be powered by a magnetized neutron star that distorts the orbit of surrounding gas. Superluminous supernovae are often more ...
