The stuff we are made from

ESA's Rosetta spacecraft continues its exploration of the comet Churyumov-Gerasimenko. Every other day they discover new exiting facts about the geology and the chemistry. Now they found exposed water ice


What really is fascinating for me is the analysts of the gasses found around the comet. It seams so familiar, so earthy. I think after this mission comes to the end, there will be no more doubt about the stuff we are made on our Earth - yes, it is old comet rubble!
