Astronomers analyzing photos taken from the Hubble telescope in 2004 have located Naiad, Neptune's closest moon, which hasn't been seen since it was discovered in the Voyager 2 space probe photographs taken in 1989. "There's a reason we had so much trouble finding it. It's in the wrong place," said astronomer Mark Showalter of the SETI Institute in Mountain View, Calif. The scientists speculate that Naiad's fellow moons gravitationally muscled it off its projected course or that the Voyager data might have been off.
