Pluto is, officially and finally, no longer a planet. I admit, I'm bummed by this. Pluto has long been my favorite
If you're not sure how to pronounce the name Charon, well, you're not alone. The moon is named for the mythological ferryman who carried people across the river Styx and into Hades. His name is pronounced with a K sound: KAY-ron. But the astronomer who discovered the moon partly suggested the name because his wife was named Charlene (and went by Char for short). So he prounced it the same way as the start of her name, SHARE-run. Personally, I prefer the classical version.
And, if you didn't hear, you might be wondering about my calling it the "biggest moon". Pluto has two other moons, Nix and Hydra, which were discovered only last summer.
Finally, in followup to earlier news about misplaced moon landing tapes, it turns out one tape was out there. A rock video producer had requested footage from the Smithsonian and got a reel of moon landing video. This was left in his archive until he saw the recent news story. Will other tapes be similarly located?
