Microbes are everywhere on Earth — in clouds in the sky, in the deepest holes ever dug in the Earth, and within and near volcanoes. There is virtually nowhere we've looked on Earth where we haven't found them. But the ones that live in extreme environment, such as places where the sun never touches, are especially intriguing because their biological processes are so unlike ours.
Now, new research in the journal Nature Microbiology inventoried chemosynthetic microbes at the bottom of the ocean and found that many more microbes thrived without sunlight than previously thought.
