Scientists have launched a fresh effort to find out what could be producing oxygen at the bottom of the Pacific Ocean.

Far below the reach of sunlight, in water cold enough to freeze most life in its tracks, scientists have found oxygen being ...

An MIT study suggests some early life forms may have evolved the ability to use oxygen hundreds of millions of years before ...

A new study published in the journal Nature Geoscience found evidence of oxygen production near polymetallic nodules located deep in the ocean. Called dark oxygen, this oxygen is being produced ...

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

An international team of researchers has devised a plasma-based approach to producing oxygen on Mars to support exploration. Oxygen is vital: it breathable environments, life support, producing fuels ...

Oxygen has been historically linked to sunlight. But a new study has suggested that oxygen may also be produced without any sunlight at all. Scientists at the University of Southern Denmark recently ...
