Anticipating my reaction, he adds, «Some people are concerned about naturalism,» but attempts to explain away that concern by saying, «If one is happy with natural explanations of the formation of stars and planetary systems, why not of plants and animals?»
Through theoretical modeling, Aurélien Crida of the University of Nice Sophia - Antipolis and Sébastien Charnoz of the University of Paris Diderot found that the moon - formation action begins at the edge of a planetary ring, where a satellite can take shape without being shredded by the gravitational pull of the planet.
His team found that by tuning the model so that the pebble formation process takes a bit longer, there is more time for the large planetary embryos to interact with each other gravitationally.
«The results confirm one of the basic ideas of planetary formation theory, that most of the Earth formed by collisions of smaller objects like carbonaceous chondrites,» says Scott Kenyon at the Harvard - Smithsonian Center for Astrophysics in Cambridge, Massachusetts.
The Mars Exploration Program studies Mars as a planetary system in order to understand the formation and early evolution of Mars as a planet, the history of geological processes that have shaped Mars through time, the potential for Mars to have hosted life, and the future exploration of Mars by humans.
Coming hot off the heels of discoveries made by other observatories, including NASA's Kepler and CoRot (the Convection, Rotation, and Planetary Transits mission, led by France's CNES with contributions from the ESA), this spacecraft is intended to build significantly on our knowledge of the universe, the Solar System, and the formation of life in general.
The simulations suggest that planetary bodies the size of the moon existed prior to the creation of the earliest chondrules, and that it was the enormous pressures produced by a collision between two such bodies that were responsible for the formation of the glassy spheres.
