I know this isn't really gossip... but WHAT???? Astronomers have decided that Pluto is no longer a planet. Our solar system now has 8 planets instead of 9. What about that rhyme that got me through science when I was in elementary school?

She served us nine what? What did she serve us???

Leading astronomers declared Thursday that Pluto is no longer a planet under historic new guidelines that downsize the solar system from nine planets to eight.
After a tumultuous week of clashing over the essence of the cosmos, the International Astronomical Union stripped Pluto of the planetary status it has held since its discovery in 1930. The new definition of what is -- and isn't -- a planet fills a centuries-old black hole for scientists who have labored since Copernicus without one. (source)
