Initially ridiculed because of a fault when it was launched in 1990, the Hubble Space Telescope has now returned valuable information about the surface of Jupiter's moon, Io. Using the Faint Object Camera of the European Space Agency, Hubble has returned comparable images to those of Voyager in 1979. Astronomers were surprised that visually very little on the surface of Io had changed. However, Hubble's unique ability to see in ultraviolet light has produced new information about the atmosphere surrounding Io. And astronomers who have used Hubble have found that high above our own atmosphere the telescope can see far better than any telescope on earth!
