A large plate is tucked under his right arm, and his left hand is holding the door open. Tombaugh is wearing glasses and looking directly at the camera.

Astronomer Clyde Tombaugh was born #OTD in 1906. He discovered Pluto in 1930, then traveled there in 2015 when NASA’s New Horizons made its flyby with some of his ashes onboard.
