The Early Atmosphere

Dinisours, early Human all examples of great history but imagine the History of the Early Worlds Atmosphere. Scientists in the "New York Center for Astrobiology at Rensselaer Polytechnic Institute" have tested the oldest minerals on Earth to "rebuilt" the atmospheric conditions on Earth very soon after its birth. The findings, which were found in  December. 1  are the first evidence of what the ancient atmosphere of the planet was like soon after its formation and directly challenge years of research on the type of atmosphere out of which life arose on the planet.

The scientists show that the atmosphere of Earth, 500 million years after its creation was not a methane, filled planet as previously stated, it was much closer to the conditions of our current atmosphere.

For many years, scientists believed that the atmosphere of early Earth was highly reduce (the oxygen was limited.) Such poor oxygen conditions would have resulted in an atmosphere filled with noxious methane, carbon monoxide, hydrogen sulfide, and ammonia. To date, there remain widely held theories and studies of how life on Earth may have been built out of this deadly atmosphere cocktail.

Now, scientists at Rensselaer are turning these atmospheric beliefs with findings that prove the conditions on early Earth were simply not conducive to the formation of this type of atmosphere, but rather to an atmosphere dominated by the more oxygen-rich compounds found within our current atmosphere including water, carbon dioxide, and sulfur dioxide.


This was a unique discovery for me, I honestly thought that the the Atmosphere could change but it shows that it has the same structer as before. I was also very interested in how it was formed and that it was also being harmed in the early stanges of Earths Life.
