The answer to one of humanity\u2019s biggest questions is complicated by a basic reality: If there is life on other worlds, it may not look familiar. A sample of rocks from Mars or another planet almost certainly won\u2019t have recognizable fossils or another similarly obvious sign of living organisms, said Mikhail Tikhonov, an assistant professor of physics in Arts &amp; Sciences at Washington University in St. Louis who studies microbial communities.<\/p>\n<p>But just because we might not recognize signs of life on a distant moon or planet doesn\u2019t mean it\u2019s actually lifeless. \u201cThere could be life forms out there that defy our imagination,\u201d Tikhonov said.<\/p>\n<p>Searching for life that we don\u2019t understand may seem like an impossible mission.

Instead of looking for particular molecules or compounds associated with life as we know it, scientists can look for telltale patterns of energy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Are we alone in the universe?
