Speed calculation proves SN 2026acxa's infrared glow is a pre-death dust echo, not freshly formed ejecta. JWST CO ...

Debris around the surviving star of the 1181 supernova forms chains of giant knots, and the star lies almost exactly at its ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

Astronomers caught a massive star exploding 500 million light-years away almost from the moment the event began. A brief X-ray flash detected on March 21, 2026 turned out to be the opening signal of ...

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 ...

Hubble observations connect galactic winds and reionization, finding that stronger outflows in six compact galaxies accompany less escaping ionizing radiation.

Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

Stars experience very violent lives that usually end in dazzling explosions, and scientists have tried for years to determine what happens to massive stars just before this bombastic finale. Now, an ...

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 ...
