SOFIA Highlights: Solar system

Occultation infographic showing Earth, Pluto, and SOFIA in the shadow of Pluto

In a special celestial event visible only from the Southern Hemisphere, Pluto passed directly between a distant star and the Earth on the morning of June 30, New Zealand time (June 29 in the U.S.). As the dwarf planet and its atmosphere were backlit by the star, this “occultation” caused a faint shadow of Pluto to move across the surface of Earth at more than 53,000 mph, creating a ripe opportunity to perform scientific analysis – if instruments and observers could be in the right place at the right time.
