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; ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

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 ...

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

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

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.

Stars of its type tend to live fast and die relatively young; whereas our star is middle-aged at about 5 billion years, Betelgeuse is 10 million years old and could go out in a supernova explosion ...

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.
