A long time ago in a galaxy far, far away there was water. Astronomers have found tell-tale signatures of water molecules in a galaxy more than 11 billion light years from Earth. Using the giant, 100-meter-diameter radio telescope in Effelsberg, Germany, along with the Very Large Array (VLA) in New Mexico, scientists detected [...]

Is this a singular event? Have other water masers been found at this great of distance? A single occurance cannot prove there were more of this type of event in the distant past.

Fraser/ Jerry. Hydroxyl masers also form at the interface of supernova shock fronts and quiescent gas/dust media, and are considered possible diagnostic tools as such. see:http://en.wikipedia.org/wiki/Hydroxyl_radical Since the emission in the refrenced galaxy is from a face-on angle, rather than the historically more typical edge-on profile, and since supernovae axisymmetry tends to align with progenitors axes, which are galactically aligned like Cepheid pulsation axes, seeing the emission from the face-on position of the galaxy is to be expected...No?

Water is not rare in type 2 supernovae ejecta clouds, which is what early "metals" in distant galaxies are thought to accumulate from. Stan Woosleys isotope table for a ~25 solar mass "supe" indicates about three solar masses of water. That's wet. :shifty: pete

That's a LOT of water. (Now I'm wondering how big a balloon...)
