Volcanic activity on Io. Footage of the Jovian moon Io, displayed on a computer screen. Io is the third largest of the moons of Jupiter. The powerful Jovian gravity powers volcanoes that can eject sulphur over 100 kilometres into space (plume visible at upper left). Hundreds of active volcanoes on Io make it the most geologically active body in the solar system. Io has been observed by a number of spacecraft, including the Pioneer and Voyager probes in the 1970s. Io was observed again by the Galileo spacecraft which orbited Jupiter from 1995 to 2003. The New Horizons spacecraft also observed Io in 2007, observing similar plumes and eruptions to those observed by earlier spacecraft. | |
