Diatomic sulfur was first discovered in comets during the close approach to Earth of comet IRAS-Araki-Alcock (C/1983 HI). The spatial distribution of S2 was restricted to within a few hundred kilometers of the nucleus, consistent with S2 being a parent molecule. This molecule has been detected in comets Hyakutake (C/1996 B2), Lee (C/1999 HI), and recently in Ikeya-Zhang (C/2002 CI), leading to the conclusion that S2 is ubiquitous in comets.
