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 ...

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

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 supernova, dubbed SN 2023ixf, is located in one of the spiral arms of the Pinwheel Galaxy, also known as Messier 101, which is 25 million light-years away from Earth, according to NASA.As ...

The supernova, now designated as SN 2023ixf, was first seen by supernova hunter Koichi Itagaki of Japan on May 19th. Star watchers at the Zwicky Transient Facility in California confirmed the ...

A new supernova that burst into the night sky in May 2023 should remain visible in the Pinwheel Galaxy for some time, astronomers say. Skip to main content. Open menu Close menu.

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 astronomers compared M31-2014-DS1's death with the only other strong candidate for a failed supernova, N6946-BH1, found 22 million light-years away in the galaxy NGC 6946, ...

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.

The most recent nearby supernova, SN 1987A, was in the Large Magellanic Cloud. The Milky Way’s youngest known supernova is called G1.9+0.3.
