The fields (polygons) and 1975 supernovae (points) surveyed by the Young Supernova Experiment and included in Data Release 1. YSE combines its observations of over 1500 square degrees of sky taken ...

Astronomers have discovered what may be a massive star exploding while trying to swallow a black hole companion, offering an explanation for one of the strangest stellar explosions ever seen.

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 ...

A new discovery about what happens when a supernova – an exploding star – and a black hole collide could change the way scientists understand the lives and deaths of stars. The finding was the first ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

The Pan-STARRS1 and Pan-STARRS2 telescopes are seen atop Haleakala. The telescopes surveyed the sky every three days for about three years and discovered thousands of new cosmic explosions. Seeing how ...

When a massive star reaches the end of its life, it can explode in a process known as a supernova. The massive star — much more massive than our sun — runs out of fuel in its core. Gravity forces the ...
