Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in ...

a neutron star is formed when a massive star undergoes a supernova explosion, while a white dwarf emerges when a star with a low to medium mass exhausts its nuclear fuel and sheds its outer layers.

Other than the announcement of its discovery in November 2022, SN 2022aajn ... what's known as a Type Ia supernova, which results from the explosion of the core of a dead star.

At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts ...

In June 2022, NASA’s James Webb Space Telescope ... a spectacular look at Wolf-Rayet 124 — a hot star riding on the verge of a supernova. Wolf-Rayet 124, or WR 124, is 15,000 light-years ...

The team uncovered supernova cataloged as AT2023 ... In the case of AT2023 ADS-V, images from 2022 and 2023 allowed astronomers to compare the star's behavior over that interval.
