Exploring the transformation of Earth from a volcanic hellscape to a potential birthplace of life during the Hadean era. Insights from a University of California study suggest that early Earth had ...

F. Theoretical constraints on oxygen and carbon dioxide concentrations in the Precambrian atmosphere. Precambrian Research 34, 205–229 (1987). Kasting, J. F. Earth’s early atmosphere.

In the early days of the Earth, no free oxygen was available. Earth's early climate lacked oxygen, which made it impossible for many creatures to survive. How did Earth's atmosphere become oxygen-rich ...

"If we could find a place on the moon that recorded this really old regolith material we might have a way to deduce what the early Earth's atmosphere was from direct measurements," Tarduno said.

According to a new study, Earth's early atmosphere hosted a 'battle royale' between iodine and oxygen -- effectively delaying the creation of a stable ozone layer that would shield complex life ...

Carbon dioxide, or CO2, was likely needed in large quantities in earth’s early atmosphere to raise temperatures sufficiently to enable the onset of the earliest microbial life. That’s because ...

Ranging from September 2004 to December 2023, it spans multiple levels of the atmosphere from ground level up to the lower edge of space, about 110 kilometers above Earth's surface. The region ...
