    The size and density of dust grains determine their response to gas drag in protoplanetary discs. Aerodynamical (size x density) sorting is one of the proposed mechanisms to explain the grain properties and chemical fractionation of chondrites. However, the efficiency of aerodynamical sorting and the location in the disc in which it could occur are still unknown. Although the effects of grain Author: forabetterchicago.comale.

Water consists of hydrogen and oxygen atoms, which are the first and third most abundant elements in the universe. According to the standard cosmology, hydrogen was formed immediately after the Big Bang, some billion years ago ( Gyr). After about 1 ms, protons and neutrons emerged from the cooling quark–gluon plasma, and after 1 s the baryonic content was forabetterchicago.com by:

With the development of space technology, exobiology has been established as a scientific discipline. The term ‘exobiology’ was introduced by Lederberg (), who recognised the emerging capabilities of space exploration for giving new impetus to biology much as the development of astronomy has broadened our understanding of the physical world and the spectral analysis of the.
