When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

A burst of light in the deep sky is doing something it should not be able to do. It looks like one supernova, but it shows up ...

Discover how the giant star WOH G64, one of the largest known, transformed in 2014 and might be heading for a supernova.

In A Nutshell A massive star in the Andromeda Galaxy faded by more than 10,000 times over a decade and vanished from view, likely collapsing into a black hole without exploding as a supernova ...

In an exciting new study published in Nature Astronomy, astronomers have unveiled unexpected findings from the XRISM satellite mission. The research team, led by experts from Japan and the U.S., ...

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

NASA’s James Webb Space Telescope has recently made a historic observation, identifying the earliest supernova ever detected. This discovery, made possible by Webb’s advanced imaging capabilities, was ...

Astronomers report a supergiant star in the Andromeda Galaxy, M31-2014-DS1, collapsed directly into a black hole without a supernova, confirming predictions of failed stellar explosions.

Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have for the first time identified the progenitor of a nearby supernova -- a red supergiant star cloaked in thick, dust-rich shrouds that ...

A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas. When you purchase through links on our site, we ...
