Everything Pluto Dissolves Into Air
So just as I was getting used to the newish pronunciations of Himalyas, Neanderthal, and Uranus comes news that Pluto, the Eddie Gaedel of the universe that was discovered only 75 years ago, really doesn't deserve its planetary status.
Because of a hacker (praise be to them), the astronomers who have found a 10th "planet"–something that revolves around our sun and is bigger than Pluto–have gone public with their discovery. Whole story here.
Ten planets instead of nine? Or nine, but not the nine you thought you knew? Weird, wild stuff.
