A strange double flash in a distant galaxy may be the first glimpse of a “superkilonova,” a cosmic one‑two punch that fuses two of the most violent stellar deaths known. Astronomers watched a massive ...

The current generation of gravitational wave detectors could "hear" the explosive supernova collapse of dying stars over 65 million light years away. When you purchase through links on our site, we ...

The brightest burst of gamma rays ever recorded was caused by the collapse and explosion of a massive star—a supernova. That’s according to a paper published last week in Nature Astronomy that used ...

A flash of energetic light lasts only ten seconds, yet it has completely turned around our understanding of the timeline for ...

The most dangerous parts of a supernova explosion are the outputs like X-rays and gamma rays. Even though they only share a small fraction of a supernova's power, they are extremely dangerous. But ...

A supernova observed last year was so bright–about 100 times as luminous as a typical supernova–that it challenged the theoretical understanding of what causes supernovae. But Stan Woosley, professor ...

"Most of the external layers of a massive star are removed during the supernova, but some material falls back, making the neutron star spin faster." When you purchase through links on our site, we may ...
