Pictures of a distant supernova remnant show two concentric rings, providing clear evidence that exploding white dwarf stars ...

(CN) — While all stars go out in a bang, some go out with two. For the first time, astronomers have recorded visual evidence ...

An international team of astronomers has discovered new structural and spectral details of SNR J0450.4−7050, a supernova ...

Astronomers have identified a new kind of cosmic explosion extreme nuclear transients so powerful they outshine typical ...

“ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain ...

Gravity can play a lot of tricks with light, and we're not just talking about black holes. Take this recent Hubble Space Telescope discovery from UC Berkeley's Patrick Kelly, for example: those ...

But it’s not big enough to supernova. To do that, a star needs to be at least eight times heavier than our sun. Those high-mass stars fuse all kinds of stuff in their cores ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions ...

Astronomers discovered a star explosion, called a supernova, in the Pinwheel galaxy, also known as "M101." The dramatic cosmic event is visible with a telescope. Here's how to see it.

It will take another supernova and lens to make a big leap in precision over the Refsdal study. A recurring image of a supernova in the constellation Cetus that’s expected to appear in 2037 ...
