Herschel also provided data about chemicals present in other objects in space. Astronomers used the data to find what other places have water, for instance. They found a pre-stellar core in the Taurus molecular cloud has as much water, in the form of ice, as millions of Earths. A protoplanetary disc around the star TW Hydrae has as several thousand times more water than Earth, in the form of water vapor. When that disc forms planets, there should be plenty of water available to cover those planets, Frank Helmich, who leads the science team for one of the instruments onboard Herschel, said in a news release from the European Space Agency.
