New observations show a star that blew up in two separate bursts, confirming a long-suspected cosmic phenomenon called a ...

The supernova remnant is located in the Large Magellanic Cloud, a Milky Way satellite galaxy, and hides a rapidly spinning neutron star. The colorful, wispy remains of a star's violent death glow ...

A star exploded as a supernova in the Pinwheel Galaxy in Ursa Major, Sky and Telescope reports. It’s bright enough to see with a small telescope.

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 galaxy, called NGC 1672, is a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado.Billions of stars fueled by hydrogen gas in the swirling arms glow ...

The subject of this NASA/ESA Hubble Space Telescope image is a supernova-hosting galaxy located about 600 million light-years ...

(CNN) — 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.

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 ...

In a galaxy far, far away, about 21 million light years away, something amazing happened. In April, I took a photo of the Pinwheel Galaxy near the Big Dipper’s handle, opposite the Whirlpool ...

Astronomers found two renegades, runaway white dwarf stars on an escape route out of our galaxy. The two stars are moving at record-breaking speeds of 5.1 million and 3.8 million mph.

The gravitational waves recorded so far were released by the mergers of massive objects such as black holes and neutron stars. But when a supernova eventually happens in our galaxy, that, too ...

The James Webb Space Telescope set its sights on a galaxy 20 million light-years away, capturing a dazzling star-forming galaxy in images streaked with the signature of passing asteroids.
