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.

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.

WASHINGTON (Reuters) -The explosive death of a star - a supernova - is among the most violent cosmic events, but precisely how this cataclysm looks as it unfolds has remained mysterious. Scientists ...

Astronomers have for the first time observed the birth of a magnetar, a highly magnetized, rapidly spinning neutron star, directly linked to some of the universe’s brightest exploding stars. This ...

The universe is almost 13.8 billion years old, but every now and then, astronomers detect echoes from its distant past. One such occasion occurred earlier in 2025, when NASA scientists reported ...

A new look at the debris from an exploded star in our galaxy has astronomers re-examining when the supernova actually happened. Recent observations of the supernova remnant called G11.2-0.3 with ...

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 ...
