MarkWhittington writes "The International Astronomical Union announced on July 2, 2013 its picks to name the two recently discovered moons of Pluto, hitherto known as P4 and P5. They will now be known as Kerberos and Styx respectively. In Greek and Roman mythology Kerberos is the name of the mythological three headed hound that guards the entrance to the underworld. Styx is the name of the river that separated the underworld from the real world. The names, picked in a popular contest, were actually the second and third choices. The first choice was Vulcan, which was officially touted because it was the name of a Roman god who was a relative of Pluto's and was associated with fire and smoke. The real reason that Vulcan shot up to the top of the list was that was a choice by Star Trek fans in a campaign instigated by actor William Shatner, who played Captain James Kirk in the original series." Shatner is sad and may lead a revolt. Phil Plait wins the award for best headline for this news.
