PASADENA, Calif. - Scientists on the Cassini mission to Saturn are poring through hundreds of images returned from the Sept. 10 flyby of Saturn's two-toned moon Iapetus. Pictures returned late Tuesday and early Wednesday show the moon's yin and yang--a white hemisphere resembling snow, and the other as black as tar. Images show a surface that is heavily cratered, along with the mountain ridge that runs along the moon's equator. Many of the close-up observations focused on studying the...

Scientists have recently discovered that the planet Saturn is turning 60 - not years, but moons. "We detected the 60th moon orbiting Saturn using the Cassini spacecraft's powerful wide-angle camera," said Carl Murray, a Cassini imaging team scientist from Queen Mary, University of London. "I was looking at images of the region near the Saturnian moons Methone and Pallene and something caught my eye." The newly discovered moon first appeared as a very faint dot in a series of images Cassini...

Saturn's moons Tethys and Dione are flinging great streams of particles into space, according to data from the NASA/ESA/ASI Cassini mission to Saturn. The discovery suggests the possibility of some sort of geological activity, perhaps even volcanic, on these icy worlds. The particles were traced to the two moons because of the dramatic movement of electrically charged gas in the magnetic environs of Saturn. Known as plasma, the gas is composed of negatively charged electrons and positively...

NASA -- Amateur astronomers are helping NASA scientists on the Cassini mission track the most powerful storm yet observed on Saturn. The storm is in a similar location to the "Dragon" storm reported last year - -http://antwrp.gsfc.nasa.gov/apod/ap050225.html so it may be a reemergence of that storm or a new storm. "Right now, Cassini is in a 40-day orbit around Saturn, and we are slowly flying over the night side, so it's difficult to see cloud features," said Dr. Michael Kaiser of...
