As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for ...

“Oxygen buildup in the atmosphere is not just how you create oxygen; it's also about how you might or might not destroy oxygen,” explained Dasgupta. Earth’s early atmosphere was stuffed with ...

Researchers think that early in its history, Venus had a thinner atmosphere and a more Earth-like environment. There are small areas of Venus' atmosphere that have more moderate temperatures.

But researchers are looking for ways to uncover clues to this transformation. “Earth’s early atmosphere has to do with the evolution of a habitable planet,” says John Tarduno, a professor of ...

Early Earth was a hellscape of molten lava and barren rock, bombarded by meteors, with no atmosphere at all. How did our familiar blue sky – the thin, life-giving band of gasses protecting our ...

Early Mars may have been a warm version of modern Titan and at least as promising a site for the origin of life as early Earth was ... shows that if the Martian atmosphere was H 2-rich at the ...

This created a miniature ocean and atmosphere, made up of his best guess at what materials were around on the early Earth. He then added some heat and two sparking electrodes to ...

While Earth's slowdown is not noticeable on human timescales, it's enough to work significant changes over eons. One of those ...

"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.
