This Planet is Only Half Covered in Lava
There are a lot of weird exoplanets out there, like 55 Cancri e (aka Janssen), which is probably half covered in lava. But the half that's covered in lava might not be quite the half you're thinking of.

The Particle So Extreme Scientists Called it OMG
In 1991, a subatomic particle smashed into Earth's atmosphere traveling faster than anything humans can replicate. It's the most energetic particle detected to date, and maybe even the fastest (except light itself). Astronomers call it...
