Bill Thompson

Dr. Bill Thompson was assigned to the scientific team on the moon of a gas giant, designated as M4C-862, in the episode, 4.19 "Prodigy". He was very excited about the discovery of tiny energy lifeforms which inhabited the moon, but, unfortunately, the lifeforms swarmed against him and killed him. Initially their behavior had been peaceful and curious, but due to reasons unknown to the SGC personnel, they turned angry and dangerous.
