Habitability and Cosmic Catastrophes,rograde rotation of our sister planet Venus can be explained by catastrophic collisions of the early planets with other planet-sized objects. Catastrophes may have happened also on later stages during the Earth’s evolution. We give a review about the possible catastrophe scenarios and address to the

The reconstruction of Earth’s history relies on evidence recovered from its rock record. From this record, we know that life originated prior to 3.8 Ga (e.g., Schidlowski et al., 1979; Mojzsis et al., 1996), that multicellular life arose at around 0.6 Ga, and

Origin of the Genetic Code and Abiotic Synthesis of Organic Compounds, code remains uncertain, and several hypotheses have been proposed. Theories include the synthesis of peptides preceding the appearance of genes (“Metabolic Model”) or molecules of nucleic acids being responsible for the storage of genetic information (“Genetic Model”).

By now, no other system than ours is known to host a habitable planet like the Earth. Assuming that solar system-like configurations are the most favorable ones where a habitable Earth might exist, we show the inf
