Galilean Satellites as Sites for Incipient Life, and the Earth as its Shelter

Abstract

Numerous problems connected with an assumption of the life origin on the Earth do not arise on Galilean satellites. Here, in presence of a practically non-salt water and of a great deal (~5-10%) of abiogenic organics, a great diversity of conditions, which are unthinkable for the Earth, were realized more than once. They were caused by global electrochemical processes in the magnetic field presence what could entail an absolute enantiomeric synthesis. The subsequent explosions of the satellites' icy envelopes saturated by the electrolysis products resulted in appearance of hot massive atmospheres and warm deep oceans and ejection of the dirty ice fragments (=comet nuclei), what led to the material exchange with other bodies, etc.
