Pluto to Make a Star Wink Out 2x This Week
On Thursday tiny Pluto will cause a bright star to fade in the nighttime sky, and an army of astronomers is fanning out across the Pacific to capture the rare event. The   unprecedented sky show involves what scientists call an   occultation—when an object passes directly in front of a star, as seen   from Earth, causing the star to dim temporarily. Starting  at  11:15 UT on June 23, Pluto and its largest moon Charon will both  occult  a very bright star. Just a few days later, beginning at 14:18 UT  on  June 27, Pluto and its smaller moon Hydra will each pass in front of a   different bright star.
"We’ve never had an event like this one we’re seeing now," said team member Leslie Young of the Southwest Research Institute in Boulder, Colorado. “We’re   getting two bright stars, both brighter than Pluto itself—as seen from   Earth—occulting Pluto just about four days apart.”…
