No collision, no life: Earth probably needed supplies from space
Earth is so far the only known planet on which life exists—with liquid water and a stable atmosphere. However, the conditions were not conducive to life when it formed. The gas-dust cloud from which all the planets in the solar system formed was rich in volatile elements essential for life, such as hydrogen, carbon and sulfur.
No collision, no life: How a cosmic crash may have made Earth habitable
Earth is the only known planet that supports life. It has liquid water, a breathable atmosphere, and the right conditions for plants, animals, and humans to exist. But when our planet first formed, it was anything but friendly to life. In fact, new research suggests that without a lucky collision with another celestial body, Earth […] The post No collision, no life: How a cosmic crash may have made Earth habitable appeared first on Knowridge Sci…
Only a later collision with a water-rich celestial body brought the elements necessary for the creation of life to the Earth, the researchers suspect. In the study published in the journal "Science Advances", the Bernese researchers showed for the first time that the chemical composition of the early Earth was completed no later than three million years after the formation of the solar system. In order to reconstruct the process of earth formati…
