The process responsible for the formation of the Earth does not imply the existence of key ingredients for life. New research, however, shows how our planet probably has acquired them.
Scientists are saying a Mars-sized planet has hit the Earth about 4.4 billion years ago. On the one hand, it served as a “donor” to the important ingredients for life, as its core was rich in sulfur. On the other – it has led to the formation of the Moon, our natural companion.
Experiments prove that much of the nitrogen and carbon of the Earth is the result of this collision. Moreover, they prove that it is quite possible that another celestial body can carry life-important ingredients through the cosmic space and they can survive after collision – something that was not yet certain.
Scientists compiled the evidence from a combination of high-temperature, high-weight tests in lab, which spends significant time in examining geochemical reactions that occur profound inside a planet under extreme heat and pressure.
This would increase our chances for the search for extraterrestrial life, because if scientists manage to suggest exactly under what impact receive these ingredients will be much easier to find them.
