Discovery of the Fifith Moon of Jupiter

Edward Emerson Barnard’s discovery of the fifth satellite of Jupiter in 1892 set off a firestorm of accolades in the press and in astronomy circles. It was the first planetary satellite discovery since Asaph Hall had discovered the moons of Mars in 1877 and the last satellite discovery by direct observation. Henceforth, astronomers would rely on photography to detect new solar bodies.
