The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

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 ...

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

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

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.

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

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that ...

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist ...

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 ...

Their formation has been an object of debate, but new observations confirm the lead hypothesis: they are the product of incredibly bright supernovae. The rest of this article is behind a paywall.
