Two of Earth’s five confirmed mass extinction events could have been caused by nearby supernova explosions stripping the planet’s ozone layer, a new study argues. Although the explanation has been ...

A type Ia supernova occurs when a white dwarf draws hydrogen from a companion. But Sirius A and B are too widely separated ...

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 ...

A wider forefoot and shorter tongue are just some of the improvements in this super foam shoe made for daily training.

The work is published in the journal Physical Review Letters. A type Ia supernova occurs in a binary system in which one of the stars is a white dwarf. The primary mechanism behind this is ...

massive O- and B-type stars that are relatively short-lived, using data from the European Space Agency’s Gaia space telescope. The calculations suggested 2.5 supernovas might affect Earth in ...
