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

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

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

In the continued aftermath of his recent inappropriate inappropriate physical actions during a Mario Kart event, a major Super Smash Bros. tournament has now ba ...

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.

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.

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.
