Watch the moment a star explodes in a supernova — something scientists have never directly witnessed like this before. The ...

A new analysis from NASA using the Hubble Space Telescope shows that the Crab Nebula, the remnant of a supernova recorded in ...

New Hubble images show the Crab Nebula is still expanding and evolving nearly 1,000 years after its original supernova explosion.

The ‘guest star’ of 185 AD has been one of astronomy's most unresolved cases for over 1800 years. Ancient Chinese chroniclers ...

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.

A supernova witnessed nearly 2,000 years ago is back in focus as NASA’s powerful X-ray telescope uncovers a hidden cosmic “bubble” that changed how the explosion evolved.

Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible ...

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.

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

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

Astronomers have detected strange "wobbles" in the light curve of a super bright supernova, hinting that a magnetar was born inside the extreme stellar explosion.
