The "snowline" is thought to partition the solar system into dry objects inside the asteroid belt, and icy objects such as comets further out. But the finding of water on Ceres suggests more mixing has occurred. Scientists have suspected that there is a substantial amount of water on Ceres for about 30 years. A study found hints of water in the form of hydroxide, a product of water's dissociation, on Ceres in 1991, but the finding wasn't confirmed by later observations. Now, Kppers and his colleagues have confirmed the finding. The researchers used the Herschel Space Observatory's spectrometer to look Nike Hypershift Green And White for signals of water. Clouds of water vapor around Ceres absorbed the heat that radiates from the dwarf planet, which Herschel's instrument detected. The team found that Ceres produces about 210^26 molecules, or 13 lbs.

the interior is 'spat out' to the surface," Kppers said much like a geyser. But these icy volcanoes eject water vapor instead of molten rock, he said. Another possibility is that ice near the surface of Ceres sublimes, or goes directly from a solid to a gas, dragging with it dust from the surface and exposing more ice. A similar process occurs on comets. "I personally consider cometary style sublimation the most likely source, because I find it difficult to maintain the internal heat over the age of the solar system to maintain volcanoes," Kppers said, but he added that more studies were needed. NASA's Dawn spacecraft, set to go into orbit around Ceres in early 2015, could answer some questions about the water on Ceres. Dawn recently visited the asteroid Vesta, a baked world whose surface is covered with volcanic eruptions. "One of th.

Without a ready supply of water, the industry couldn't survive, Mathis said. Astronomers have discovered direct evidence of water on the dwarf planet Ceres in the form Nike Dunks Pigeon
One possible source of the water is icy volcanism. "It is like volcanism in that hot material from Nike Lebron Soldier 9 Youth

of vapor plumes erupting into space, possibly from volcano like ice geysers on its surface. Using European Space Agency's Herschel Space Observatory, scientists detected water vapor escaping from two regions on Ceres, a dwarf planet that is also the largest asteroid in the solar system. The water is likely erupting from icy volcanoes or sublimation of ice into clouds of vapor. "This is the first clear cut detection of water on Ceres and in the asteroid belt in general," said Michael Kppers of the European Space Agency, Villanueva de la Caada, Spain, leader of the study detailed today (Jan. 22) in the journal Nature.
