The Hubble Telescope has spotted a 5th moon for Pluto. So far, neither it nor moon 4 has names, they are just referred to as P4 and P5. Both are very small and seem to be related to the orbit of Pluto's largest moon, Charon. Pluto (which is smaller than the earth's moon) and Charon are similar to the earth in that they are considered more of a dual planet system than planet and orbiting moon. The two other moons of Pluto are Nix and Hydra. Read the full article on this discovery in the Scientific American.
Nicholas Campion, Kepler College board member and Senior Lecturer at the University of Wales, Trinity St. David, has an interesting commentary on the Huffington Post.
"It's a shocking fact that there has never been a human culture which has not related its myths, institutions and identity to the stars. This is as true of the modern West as it was of our stone-age ancestors, and is as relevant to the last, surviving, indigenous inhabitants of Amazonia, as it is of today's American astronomers. After all, no scientist spends cold nights scanning the sky in search of new stars, or long hours decoding data from deep space, if the exercise is completely meaningless."
