Europa Discovery Increases Odds of Life On Jovian Moon.

tetrahedrassface writes "Observations of spectral emissions from the surface of Europa using state of the art ground based telescopes here on Earth have lent data that indicate the surface of the Jovian moon is not merely ice that is not dynamically linked with the vast ocean below. The observations carried out by Caltech's Mike Brown, and JPL's Kevin Hand show that water is making it from the ocean below all the way up to the surface of the moon. In their study they noticed a dip in the emission bands around lower latitudes of the moon, and quickly honed in on what they were seeing. The mineral of interest is epsomite, a magnesium sulfate compound that can only come from the ocean below. From the article: 'Magnesium should not be on the surface of Europa unless it's coming from the ocean," Brown says. "So that means ocean water gets onto the surface, and stuff on the surface presumably gets into the ocean water.

Not only does this mean the ocean and surface are dynamically interacting but it also means that there may be more energy in the ocean than previously thought. Another finding is that the ocean below the icy surface of Europa is basically very similar to an ocean on Earth, giving the neglected and premier solar body for life past Earth another compelling reason for being explored."
