Chasing Pluto's Earthly shadow

Abstract

Schilling talks about SOFIA, a converted Boeing 747SP which is the largest airborne observatory in the world. The refiners have been busy: gone are the familiar rows of airline seats and overhead bins, ripped out to make room for a multitude of computer monitors--and a 2.5--meter telescope. SOFIA is flying for a special reason. Tonight--29 June-Pluto will pass in front of a star in the constellation Sagittarius.
