Description: This animation shows the event that helped to discover the rings of Uranus. On March 10th, 1977 Uranus transitted before the star SAO 158687, the event was observed and recorded by Kuiper Airborne Observatory. A few unexpected and momentary falls of the brightness of the star were found, and the only explanation was that there must be thin rings around Uranus. Those rings were photographed by Voyager 2 in 1986.
