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. Hubble has captured the impact of a comet on Jupiter, immense storms on Neptune and even tiny dwarf planets at the edge of our Solar System. The veteran telescope keeps a watchful eye on our solar backyard.
