Potential targets in the search for extraterrestrial life.Discussion of the potential for increasing understanding of the origins of terrestrial life by examination of other planets. If living organisms should be found on another planet, they could only have been transported from an inhabited planet or originated independently. The fundamental chemical and structural attributes of terrestrial organisms are so remarkably uniform that any living forms outside the terrestrial blueprint would almost certainly be regarded as alien organisms. It has been shown experimentally by various investigators that life can exist in an extremely wide range of temperatures and pressures. The presence of an atmosphere appears to be necessary.
