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.

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

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 ...

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

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

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

A cosmic mystery surrounding the universe's most dazzling explosions, superluminous supernovas, appears to have been solved by scientists studying a colossal stellar event a billion light-years from ...

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

An international team of astronomers has carried out photometric and spectroscopic observations of SN 2024abvb—a recently ...
