New Neptune Moon Discovered by NASA's Hubble Telescope

Scientists studying images from NASA's Hubble telescope have discovered a new moon around Neptune.  The moon measures approximately 12 miles across and is the smallest of Neptune's moons.  Mark Showalter of the SETI Institute in Mountain View, CA, located the newest moon by observing a white dot which was shown to orbit the planet every 23 hours.
