PIX4630295: The formation of the Solar System - Artist view - Forming solar system - Artist view - Artist view of the gas and dust disc (protoplanetary disc) around the Sun. Little by little rocks will gather, accrete, to form planets. Planetesimals - the seeds of planets crash together in the solar nebula, gradually growing larger, Dixon, Don (b.1951) / Bridgeman Images
PIX4632636: Comets have the origin of life on Earth - Comets bring life on Earth - An artist's view of the Earth bombed by comets 4 billion years ago. Comets may have brought the molecules necessary for the appearance of life on Earth. The Moon at that time was much closer to Earth than today. Impacting comets may have brought life to the early Earth. 4 billion years ago, Moon was closer than today / Bridgeman Images
PIX4632660: Life on Earth: the Sun and Comets - Life on Earth: Sun and Comets - All living organisms on Earth are exclusively left amino acids. The origin of life homochiralite, the asymmetry present in amine acids, could be derived from solar radiation distruding the right amino acids accumulated on comets during the formation of the solar system. Life on Earth is made of left handed amino acids, almost exclusively. The origin of biomolecular homochirality could come from the sun light destroying right handed amino acids in comets during the formation of solar system / Bridgeman Images
