Way back in the year 775, it looks likely that the Earth was slammed with a massive burst of gamma rays, briefly soaking the planet in quite a bit of radiation. This radiation spike was measured by studying tree rings in Japan and rocks in Antarctica, pinpointing it to 775, the year when Baghdad was the world’s biggest city.


Google recently released this cool little educational tool/show off thing for Google Chrome. It’s the nearest 100,000 stars from Earth and you can scroll and zoom through this entire chunk of galaxy. Trippy.
This is a fascinating read about why Obama has strange swath of strong supporters in the South that happens to exactly mirror the coastline of the southeast corner of America during the Cretaceous era, 129 million years ago. Yes, ancient geology still plays a role in modern American politics.
The intricate circular pattern above wasn’t made by any manmade source, nor through some alien undersea device. Instead, it was made by a very ambitious puffer fish off the coast of Japan.
It’s an absolute fact of nature that dinosaurs are fucking awesome. And it seems like every time someone discovers a new dinosaur, it ups the awesome bar. Like this beauty, with fangs and spikes like a porcupine. I want one of these as a pet.

Almost every simple definition of a galaxy would probably be something like “a collection of stars and star systems held together in a group”. But scientists have discovered that galaxies can contain almost nothing at all. Nothing but dust and dark matter.
There are plenty of binary star systems out there, but it’s often been thought that there’s an absolute minimum distance two starts can orbit each other before they just slam into each other and form a single star. But several pairs of new red dwarf stars are challenging that minimum distance.
