Scientists 'surprised'
This week in the journal 
Nature, an international team of  scientists reported evidence for hydrothermal vents on the Saturnian  moon Enceladus, with temperatures of its rocky core surpassing 90C in  spots. The discovery, if confirmed, would make Enceladus the only place  other than Earth where such chemical reactions between rock and heated  water are known to be occurring today -- and for many scientists, it  would make Enceladus a most promising place to look for life.
  "The most surprising part is the high temperature," said Hsiang-Wen  Hsu, a scientist at the University of Colorado's Laboratory for  Atmospheric and Space Physics and lead author of the paper. "But that's the number we could derive."
surprised. :lol:
