Astronomers uncover the first direct evidence for how some white dwarf stars explode, confirming the long-debated ...

An unusual star system created more of a fizz and less of a bang when it exploded in a supernova. The “ultra-stripped” supernova led researchers to discover the two stars 11,000 light-years ...

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

At its closer distance to Earth, the supernova remnant would be about 46 light-years wide. If it were much farther away, it would be a much larger cloud—around 157 light-years across.

This new supernova has appeared in a galaxy — a star city — beyond our own. The galaxy is known as the Pinwheel Galaxy, (also designated as Messier 101, or M101) and is a large, loosely wound ...

The supernova SN2023ixf was discovered just 21 million light years away—essentially next door, as exploded stars go.

A sparkling new supernova has appeared in the night sky, and a telescope atop Mauna Kea in Hawaii was perfectly poised to capture the aftermath of the cosmic burst.

When a supernova was seen glittering in the night sky for six months in 1181, it was so bright that Chinese and Japanese astronomers recorded it as a “guest star” in the Cassiopeia constellation.
