Supernovae and Extinction Events
Recent research suggests there may be a link between a supernova about 2.6 million years ago and the extinction of a large number of marine megafauna on the Earth at the time.

A light hearted look at how you might make a blackhole if you happen to have a large star handy.
Supernovae cause the biggest explosions in the universe, often out shining their host galaxies. There’s plenty of flavours of supernova and they aren’t all just big stars blowing up.
Magnetars are a fascinating type of object that are really mind boggling. These incredibly powerful star remnants are worth giving a closer look.
A great reason to look up at the night sky is that you might see a supernova like the the one that Albert Jones spotted in 1987.
(And we can do something about it.)
Life needs CHNOPS, the six essential elements Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulphur. Curiosity found them on ancient Mars, but a new study shows Earth was born without them. Only a lucky impact with Theia made our world habitable. In contrast, Venus never stood a chance. Meet the three planetary siblings and discover why only Earth became a cradle for life.
Mars’s mantle contains ancient fragments up to 4km wide from its formation—preserved like geological fossils from the planet’s violent early history.
Cosmic rays are hitting the atmosphere constantly. One of the products of the collisions is muons, and we can detect muons on the surface of the Earth to learn about the cosmic rays.
