This movie made up of frames taken by the MESSENGER space probe as it passed by Earth on its way to Mercury is pretty cool. Makes you think…

The more we learn about the solar system, the stranger the place gets. Cassini recently discovered ice volcanoes on Saturn’s moon Enceladus. I like where they’re talking about 110 Kelvin being warm. At -261 F, that’s positively balmy.

Astronomers have discovered a tenth planet that’s larger than Pluto, and more than twice as far from the sun. No word on a name yet. Hopefully they can come up with something better than Quaoaoaoar.
