A new study explains how some supernovae are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...

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.

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

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

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.
