Astronomers have finally found evidence for a proposed mechanism for a special kind of supernova, known as a Type Ia ...

For example, another Milky Way red giant known as VY CMa, located 3,900 light-years away from Earth in the constellation Canis, is thought to be much closer to the moment of its death than Betelgeuse.

The red supergiant in question was about 500 times larger than the sun, and it’s located at redshift three, which is about 60 times farther away than any other supernova observed in this detail.

Before 1987, for example, astronomers thought only red supergiants could blast into a supernova. But in 1987, a giant blue star in another galaxy exploded. We clearly still have a lot to learn.

Betelgeuse, a bright red star in Orion, is exhibiting unexpected behavior that could lead to a supernova and neutrino rain on Earth.

A supernova is a stellar explosion, ... Shock cooling of a red-supergiant supernova at redshift 3 in lensed images. Nature, 2022; 611 (7935): 256 DOI: 10.1038/s41586-022-05252-5; ...

The stunning Supernova 1987A is roughly 168,000 light-years away from Earth and located in the Large Magellanic Cloud.

Astronomers developed an "early-warning system" to alert scientists when a star is on the verge of dying in a supernova explosion. Until now, it's been difficult for scientists to observe the ...

An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 billion years after the Big Bang, or more than 11 billion years ago.

The red supergiant in question was about 500 times larger than the sun, and it's located at redshift three, which is about 60 times farther away than any other supernova observed in this detail.
