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.

Researchers identified a "forbidden range" of black-hole masses more than 45 times the Sun's mass, where stellar-origin black holes are rare. The gap aligns with models in which such stars explode via ...

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 ...

"For the most part, massive stars make black holes. The more massive the star, the heavier the black hole," Fishbach said, until stars reach a certain mass threshold beyond which the physics of their ...

It's never too late to solve a cold case. A new paper from Syracuse University researchers proposes an explanation for both a mysterious stellar object discovered in the year 2013 and an astronomical ...
