Re: NASA to announce "major discovery" that could boost chances of life on other worl
They have known of bacteria that lives without oxygen for a long time. bacteria that live in anoxic (oxygen free or oxygen starved) regions are critical to the nitrogen cycle (denitrifying bacteria that converts nitrates into nitrogen gas) . The life in and around the oceanic plumes (as well as sulfur consuming cave bacteria) are significant because they depend ob a source of energy independent of the sun and photosynthesis.
Cool - but I'm not confused.
Didn't they have a revelation when they discovered bacteria that thrived without oxygen?
As well as microbes and sea-cumbers that reveled in heat vents and plumes on the ocean floor?
