Planeten- und Sternentstehung
SummaryAstronomers from McMaster University and the Max Planck Institute for Astronomy have completed calculations that lead to a consistent scenario for the emergence of life on Earth, based on astronomical, geological, chemical and biological models. In this scenario, life forms a mere few hundred million years after Earth’s surface was cool enough for liquid water; the essential building blocks for life were formed in space during the formation of the solar system, and delivered to warm little ponds on Earth by meteorites.
