Scientists Celebrate Pluto’s Discovery With A Retrospective Of Its Greatest Images
“In 1978, our telescopes had advanced enough to determine that it had a large satellite: the giant moon Charon. Through occultations of distant stars, we determined Pluto had an atmosphere that changed over time, growing larger near perihelion. 1994 saw the first optically-corrected pictures of the Pluto-Charon system by Hubble, the first image to resolve these worlds independently.”
On this date in 1930, the first world beyond Neptune in our Solar System was discovered. Now known as Pluto, our images and understanding of it have progressed dramatically through the years. It is one of nature’s most fascinating objects, and our ever-improving sights of the world are only eclipsed by the scientific knowledge we’ve continued to glean. It’s the largest object in all the Kuiper belt with five moons of its own, and it tells a story unique in all the Universe.
