English astronomer, mathematician and physicis Edmond Halley died #OTD in 1741.
Halley is famous in his own right for analyzing the orbits of comets, which he showed to be elliptical and periodic. Halley's Comet returned, as he predicted, in 1758, 15 years after his death. Halley's discovery of stellar motion, though less well known than his comet, was no less an achievement. No longer were the stars believed fixed, either to an outer sphere or in space. via npub1pzhdvpcfgf6dplzzxugwdkdu4gxvjryvngn90ufq7xcvspe0tvnqdpppzp (npub1pzh…ppzp)
