CAPE CANAVERAL, Fla.—The Hubble Space Telescope has been hit with computer trouble, with all astronomical viewing halted, NASA said Wednesday.

The orbiting observatory has been idle since Sunday when a 1980s-era computer that controls the science instruments shut down, possibly because of a bad memory board.
