Researchers find evidence of photosynthesis deep within the ocean

The discovery of green sulfur bacteria living near hydrothermal vents has major implications for where photosynthesis happens and where life may reside

A team of researchers, including a photosynthesis expert from Arizona State University, has found evidence of photosynthesis taking place deep within the Pacific Ocean. The team found a bacterium that is the first photosynthetic organism that doesn't live off sunlight but from the dim light coming from hydrothermal vents nearly 2,400 meters (7,875 feet) deep in the ocean.
