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.

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.

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

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 ...

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.

The supernova, named SN 2023ixf, is located 21 million light-years away. It should remain visible with the aid of a telescope for at least a few months, astronomers said.

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.
