JAMES W. CHRISTY
The astronomer who discovered Charon signs on this printed 8½x11 image.
Printed photograph signed in ink: "JW Christy", in black in, 8½x11, image 5¾x3. James W. Christy (b. 1938) is an American astronomer and scientist. Christy was working as a scientist at the U.S. Naval Observatory in 1978 when he discovered Charon, a moon of Pluto, while studying plates of the planet's orbit and position. The discovery was at first not entirely accepted, with some believing that perhaps it was simply a giant mountain on Pluto, and not a moon. But after calculating orbits and eclipses, Charon was confirmed as a moon. In late 2008, an asteroid was named in his honor. Folds. Image faded (print error). Fine condition.
