Study: Comet 67P/Churyumov-Gerasimenko’s Water Has Similar Molecular Signature to Earth’s Water
Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have helped deliver water to Earth. This false-color four-image mosaic comprises images taken from a distance of 28.7 km from the center of Comet 67P/Churyumov-Gerasimenko on 3 February 2015. The mosaic measures 4.2 x 4.6 km.
