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

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

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

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 ...

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.

The new observations reveal that its famous "firework" filaments are not smooth streaks, but chains of tiny knots. The analysis of the images, led by Timothy Cunningham at the University of Warwick ...

As a star nears the end of its life, it faces two very different fates: It can explode as a supernova, leaving behind a ...

Evidence for hypernovae, theorized to be the most powerful explosions in the universe, has been disputed in two papers by ...

When a star reaches its final stages of life, it ends in a bright and powerful explosion called a supernova and scatters material across the universe. A new study led by a University of Hawaiʻi at ...

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 ...
