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.

The signals provide astronomers with a look into the life, and death, of a massive star exploding into a supernova.

In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years ...

Astronomers evaluate how the Vera C. Rubin Observatory can detect and localize the next Milky Way core-collapse supernova using neutrino alerts and optical surveys.

What happens to a large star near the end of its lifetime before it explodes as a supernova? This is what a recent study ...

T Coronae Borealis, a star system 3,000 light-years away, is expected to erupt as a nova in June 2026, briefly becoming ...

Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before ...

Astronomers have long searched for clues that a hidden companion star sits out of view near the red supergiant ...

Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...

Solar storms are eruptions that release some of the energy stored in the sun's strong magnetic field. These can create ...

From planet-scorching stellar outbursts to cataclysms so powerful they shiver the very fabric of spacetime, these are some of the biggest blasts our cosmos has to offer ...
