Water reservoirs spotted in Taurus constellation    Posted by TG
Daily Staff  The ESA's Hershel space observatory recently
discovered enough water vapor to fill Earth's oceans more than
2000 times over in a gas and dust cloud that is on the verge of
collapsing into a new Sun-like star.    As Dr. Paola Caselli
from the University of Leeds explains, stars form within cold,
dark clouds of gas and dust - 'pre-stellar cores' - that contain
all the ingredients to make solar systems like our own. 
However, the new Herschel observations of a cold pre-stellar
core in the constellation of Taurus known as Lynds 1544 are the
first detection of water vapor in a molecular cloud on the verge
of star formation. Indeed, more than 2000 Earth oceans-worth of
water vapor were detected, likely liberated from icy dust grains
by high-energy cosmic rays passing through the cloud.  "To
produce that amount of vapour, there must be a lot of water ice
in the cloud, more than three million frozen Earth oceans'
worth," said Caselli.  "B
