Ancient white dwarf explosions seem to disobey long-established "rules"

White dwarf stars have mostly been thought to follow very specific “rules” – if they’re over a certain mass limit, they’ll explode in a supernova with a very predictable brightness and time. But now Caltech astronomers have found a strange tw… Continue reading Ancient white dwarf explosions seem to disobey long-established "rules"

White dwarf supernova observation is a first for NASA's TESS mission

Artist concept of the TESS spacecraft which recently observed a supernova and the elemental content of ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) was built to search for new planets, but astronomers at Ohio State discovered that it could also observe supernovas created by exploding white dwarf stars. This development means we might soon have a better idea about why they explode, and what they leave behind in the process.

First detection of polarized radio waves from gamma ray burst sheds light on collapsing stars

The first polarized light from a gamma ray burst seven billion light years away is helping astronomers to gain a better understanding of collapsing stars and other high-energy phenomena. Originating from gamma-ray burst GRB 190114C in the con… Continue reading First detection of polarized radio waves from gamma ray burst sheds light on collapsing stars

Supernovae-induced lightning may have encouraged humanity's ancestors to walk upright

Cosmic rays thrown out by dying stars may have made lightning strikes more common on ancient ...

A bombardment of cosmic rays from ancient supernovae may have triggered a series of events that encouraged early human ancestors to walk upright, according to a new study published in the Journal of Geology. The scientists behind the research believe that the cosmic explosion could have helped trigger a shift in Earth’s environment that forced humanity’s fore bearers to adapt.

Scientists Think an Exploding Star Helped Kill Off the Megalodon

An Astrobiology study proposes that an ancient supernova could have exposed Megalodon and other large ocean animals to deadly muon radiation. Continue reading Scientists Think an Exploding Star Helped Kill Off the Megalodon
