An active volcanic eruption on Jupiter's moon Io was captured in this image taken on February 22, 2000 by NASA's Galileo spacecraft. Tvashtar Catena, a chain of giant volcanic calderas cantered at 60 degrees north, 120 degrees west, was the location of an energetic eruption caught in action in November 1999. A dark, 'L'-shaped lava flow to the left of the centre in this more recent image marks the location of the November eruption. White and orange areas on the left side of the picture show newly erupted hot lava, seen in this false colour image because of infrared emission. The two small bright spots are sites where molten rock is exposed to the surface at the toes of lava flows
