Astronomers have spotted a "cosmic birth" which outshines our sun by more than 10 billion times for the very first time. A superluminous supernova, first detected in December 2024, has provided ...

Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

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 ...

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

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

New research suggests that the highly magnetized remnants of stars are responsible for powering some of the universe’s most brilliant supernova explosions ...

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.

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

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

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 ...
