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

Over a decade ago, NASA launched two probes to investigate the Van Allen belts —two rings of high-energy particles that encircle the Earth and protect it from harmful solar storms and cosmic radiation ...

KENNEDY SPACE CENTER — The nonprofit Florida Council of 100 sent a letter to Florida’s congressional leaders to show their support for the relocation of NASA’s headquarters to the Sunshine State. The ...

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.

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

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

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 ...

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 ...
