The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion. Previous images of the explosion’s remnants had also captured a sphere of long, ...

Astronomers captured the clearest view yet of Pa 30, the likely remains of a stellar explosion witnessed nearly 850 years ago ...

Over the decades leading up to the explosion of the rare and luminous Type Ia supernova SN 2022erq, the mass-loss rate of its ...

The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots ...

A spectacular supernova, SN 2026aaiv, has erupted in the spiral galaxy NGC 7331, located 45 million light-years away in the Pegasus constellation and visible from both hemispheres.

Learn about the remnant of a historic supernova observed around 850 years ago and the zombie star that has survived at its center.

A massive star does not always go out in a brilliant supernova. Some instead collapse into black holes, potentially with little or no visible explosion. What determines which path a dying star takes ...

UC Berkeley supernova and black hole expert Alex Filippenko will share the 2026 Gruber Cosmology Prize, which was announced today (May 19) by the Gruber Foundation. The prize, one of the most ...

In recent years, a handful of unusual stars have been cited as evidence for extraordinarily powerful stellar explosions called hypernovae. New research suggests these stars can be explained without ...

Betelgeuse is a nearby red supergiant living through the late stages of a massive star’s life. It will eventually end in a supernova, and models of such an event suggest a display bright enough to ...

Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice ...

Pa 30’s apparent streaks are chains of enormous gas knots, while its surviving star shows little sideways recoil from the ...
