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

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

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

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

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 ...

For more than a decade, a ghostly shell of radio light sat in survey data, too faint and ambiguous to be called anything more ...

When the first gravitational wave (GW) was detected back in 2015, scientists said they had opened a new window into the Universe. While most of astronomy is based on detecting electromagnetic energy, ...

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.

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

New research explains why some black holes are missing, showing how exploding stars stop certain black holes from forming.
