Oxygen fills the air today, but for most of Earth’s early history it barely existed. Scientists say the atmosphere did not hold steady oxygen until about 2.

Scientists have discovered oxygen is being produced extremely deep below the ocean's surface, changing how we think about life at the bottom of the sea. Researchers discovered the presence of strange ...

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

"Dark oxygen" is being produced deep in the ocean, and scientists are baffled by the strange phenomenon, according to a new study. In science class, kids learn that plants need sunlight to do ...

You are taught early in science that oxygen on Earth comes from sunlight. Plants, algae, and cyanobacteria use light to split water and release oxygen, shaping the atmosphere and making complex life ...
