A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar ...

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's ...

According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here ...

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 analysis from NASA using the Hubble Space Telescope shows that the Crab Nebula, the remnant of a supernova recorded in 1054, is still rapidly expanding, offering rare, direct evidence that the ...

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.

An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The ...

Astronomers call this "eruptive mass loss," and it's a stellar drama we're still trying to fully grasp.
