What's the deadliest part of a supernova explosion? To estimate this we have to look at what the actual destructive ...

Specifically, the findings support the hypothesis that supernovae could have triggered two of the so-called "big five" mass ...

But it's not going to hurt us. Betelgeuse is the shoulder of Orion, a red giant sitting about 500 light years away. It's huge ...

At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova ...

The rate of stars going supernova near Earth appears to match two mass extinctions -- 372 million years ago and 445 million ...

How could they? A star from dozens of lightyears away was to blame for what would soon happen. Cosmic rays from a nearby ...

A stunning Hubble image showcases a spiral galaxy seemingly intertwined with a nearby star—but looks can be deceiving! This ...

The red supergiant star Betelgeuse was captured by the Herschel Space Observatory. There are only two nearby stars that could go supernova within the next million years or so: Antares and Betelgeuse.

The dense core that is left over is known as a neutron star. These are much denser versions of white dwarfs, but they are actually smaller, about the size of Manhattan. Our sun is too small to go ...

As part of this, the research team calculated the supernova rate within 20 parsecs of the Sun, or approximately 65 ...
