11,000 people have been evacuated from the area surrounding Mount Merapi, as lava and superheated gas poured from the volcano. (This is the same area affected by last week's major earthquake.) Merapi is one of the world's most active and unpredictable volcanos, and some scientists have suggested that the earthquake contributed to this latest round of volcanic activity.
Saturn's moon Titan is the only satellite (moon) in our solar system that has a dense atmosphere. Nitrogen is the main component of this atmosphere and methane the second most important. The Cassini spacecraft photographed Titan as it passed by on October 26, 2004. Later analyses of the images revealed a cryovolcano that spews ice instead of lava. This finding is reported by Christopher Sotin and associates at Universite de Nantes and the Universite de Paris-Sud in France and other institutions in Germany, Italy, and the USA (Arizona, California, Colorado, New York, Washington). This giant ice volcano may also release methane into the atmosphere; however, the images show that a widespread methane ocean does not exist. Because Titan's atmosphere is similar to that of Earth, scientists are studying Titan for clues to the origin of life.
