Special Issue Information

Dear Colleagues,

Astrobiology as a science has numerous challenges. As a continuation of previous Special Issue, "Challenges in Astrobiology" (http://www.mdpi.com/journal/challenges/special_issues/challenges-astrobiology), "Challenges in Astrobiology II" will address following topics:

Definition of life; Origins of life: what came first, genetic material, such as RNA, or proteins; Origins of chirality in the biochemical molecules; Problems in functioning of the biomolecules which do not have proper chirality or have a mixed chirality; Viruses and the origins of life; Viroids and subviral particles: are they close to the RNA world; The RNA world: is it a result of a genetic takeover from a simpler system; Evolution of life: punctuated equilibria, graduated equilibria; Catastrophic events on Early Earth: did they destroy original life; Chemistry on meteorites and asteroids: what does it tell us about the extraterrestrial chemical possibilities; Did life arise on the Earth several times; Catastrophic events and Mass Extinctions. Future of life on Earth; Extraterrestrial life: would it be similar to ours; Extreme life and extreme environments. Planetary protection: are we doing a good job; Protection of Earth as the host for life on Earth: are we doing a good job; Biogeomarkers identification; and Habitability: from microbes to humans and from our solar system to exoplanets.
