Today’s climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. By analyzing clues contained in rocks, scientists at the ...

For now, complex life flourishes on our planet thanks to its supply of oxygen. But Earth's atmosphere wasn't always like it is today, and scientists predict that in the future, it will revert back to ...

High-resolution isotope data show that a modern-like, oxygen-rich atmosphere was not established until 410 million years ago, supporting a 2-billion-year transitional oxygenation of Earth’s surface.

Scientists have found a way to turn carbon dioxide and methane, the two most notorious greenhouse gases, into useful chemicals without any expensive catalysts, using only light. For roughly 2 billion ...

A complex web of interactions between geological features including volcanoes, subsurface mantle, oceans and the atmosphere created the chemical mixture necessary for early life to oxygenate our ...

The growing list of “firsts” for Perseverance, NASA’s newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet’s thin, carbon dioxide-rich atmosphere into oxygen. A ...

(Phys.org)—A small team of researchers in the U.S. has found evidence in rock samples that suggests that oxygen levels during the Lomagundi Event were high enough to support the advancement of life on ...

For now, life is flourishing on our oxygen-rich planet, but Earth wasn't always that way – and scientists have predicted that, in the future, the atmosphere will revert back to one that's rich in ...
