As the Galileo spacecraft travelled towards Jupiter in 1992, it imaged the Moon's north pole, and this mosaic photograph was stitched together from 18 different shots. In this image, the contrast between the Moon's bright and shadowy faces is clearly visible. The Moon's dark craters differ from the craters usually seen from Earth because they are large pools of hardened lava. The Moon is known to have had intense volcanic activity in the past, and traces of this activity can still be seen in some areas. For example, Apollo 15 astronauts discovered traces of volcanic eruptions on the Moon in 1971.
