Artist's concept of dwarf planet Eris

For nineteen years, NASA/ESA’s Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy but it has also helped scientists learn more about our own Solar System. From its vantage point 600 km above the Earth, Hubble has studied every planet in our Solar System except Mercury where light from the Sun would damage its instruments. Part of Hubblecast 27, this clip is an artist’s concept of dwarf planet Eris
