NASA's Hubble Space Telescope has detected the 14th known moon orbiting Neptune. The moon was named S/2004 N 1 and was discovered by Mark Showalter of the SETI Institute in California on July 1 while studying the faint arcs, or segments of rings, around Neptune. S/2004 N 1 is about 12 miles across which means it is Neptune's smallest moon. It is so small and dim that it's roughly 100 million times fainter than the faintest star that can be seen with the naked eye.
