Enceladus as a place of origin of life in Solar System

Czechowski L.

Geological Quarterly

2018

Vol. 62, No. 1

172--180

Enceladus, a satellite of Saturn, with its radius of 250 km, is the smallest geologically active celestial body in the Solar System. My model of core origin and evolution indicates that for hundreds of My after accretion Enceladus was an appropriate body for an origin of life. I continue consideration of the hypothesis that Enceladus was a cradle of life in the Solar System. I found that simple organisms could be ejected in icy grains into the space by volcanic jets or by meteoroid impacts. Several mechanisms could be responsible for later transport of the grains to the early Earth and other terrestrial planets. Eventually I suggest that Enceladus is the most appropriate body for a cradle of life in the Solar System.
