When did the rings of Uranus were discovered? As most people would answer 1977, a British astronomer has a contrarian view. The rings were discovered by William Herschel in 1797.
The Register is reporting that Dr. Stuart Eves from the Surrey Satellite Technology Limited, is contending that that Herschel's writings indicated that he saw a possible ring orbiting Uranus in 1797, some 180 years earlier.
Eves has apparently discovered the smoking gun among Herschel's notes, which says "February 22, 1789: A ring was suspected". The rings were first photographed in 1986 by the Voyager 2 during its flyby.
