Astronomers have identified a newborn magnetar as the power source behind SN 2024afav, a superluminous supernova whose brightness far exceeded what standard explosion models could explain. The finding ...

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 ...

Researchers say the "powerful engine" behind superluminous exploding stars had been hidden for years — until a "chirp" from the cosmos helped confirm their link.

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...
