Oxygen is everywhere on Earth today. But that hasn’t always been the case. Scientists think oxygen only became a lasting part ...

Aerobic respiration began hundreds of millions of years earlier than previously thought, a new study suggests.

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 ...

A number of hypotheses have been used to explain how free oxygen first accumulated in Earth’s atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. Now a new model offers ...

Earth’s magnetic field and atmospheric oxygen appear to have moved in sync for half a billion years, pointing to a surprising connection between the planet’s deep interior and life-supporting ...

India, Feb. 9 -- Oxygen is a vital and constant presence on Earth today. But that hasn't always been the case. It wasn't until around 2.3 billion years ago that oxygen became a permanent fixture in ...

Researchers uncovered that trace compounds like nickel and urea may have delayed Earth’s oxygenation for millions of years. Experiments mimicking early Earth revealed how their concentrations ...
