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

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 ...

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 ...

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

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

A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a ...

Researchers found a magnetic star core acting as a high speed engine to power a record breaking luminous supernova.

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

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.

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...
