Astronomers have turned a famous star explosion into a 25‑year time‑lapse, using a NASA telescope to watch the superheated gas race through space and slam into its surroundings. The new study using ...

In 2019, Betelgeuse mysteriously dimmed by a third of its brightness. Hubble data reveals the cause: a massive Surface Mass Ejection that disrupted its pulsation cycle. Explore how a star 764 times ...

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

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

For the first time, we have a front-row seat to one of the most violent events in the universe: a supernova. But there’s a catch - the shape of the explosion was not what we expected. In this video, ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

The phenomenon of fast radio bursts is one of the greatest mysteries of modern astrophysics. Until now it has been believed that their source is magnetars. The latest discovery, in which dr Marcin ...

XRISM’s high-precision X-ray data revealed unusually strong signatures of chlorine and potassium inside the Cassiopeia A supernova remnant. These levels are far higher than theoretical models ...
