Where and how are we looking for evidence of life? ... Because the universe is an immense place, it makes sense to search for evidence of life in more than one way. In addition to focusing on what we know about life on Earth, especially in extreme environments, astrobiology currently comprises three basic types of searches in space, each employing different technologies, looking in different places, and expecting to find different kinds of data: . ...
