Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even habitable.<\/p>\n

The search for life beyond Earth has led scientists to explore many suggestive mysteries, from plumes of methane on Mars<\/a> to clouds of phosphine gas on Venus<\/a>. But as far as we can tell, Earth\u2019s inhabitants remain alone in the cosmos.<\/p>\n

Now a team of researchers is offering what it contends is the strongest indication yet of extraterrestrial life, not in our solar system but on a massive planet, known as K2-18b, that orbits a star 120 light-years from Earth. A repeated analysis of the exoplanet\u2019s
atmosphere suggests an abundance of a molecule that on Earth has only one known source: living organisms such as marine algae.<\/p>\n

\u201cIt is in no one\u2019s interest to claim prematurely that we have detected life,\u201d said Nikku Madhusudhan, an astronomer at the University of Cambridge and an author of the new study<\/a>, at a news conference on Tuesday. Still, he said, the best explanation for his group\u2019s observations is that K2-18b is covered with a warm ocean, brimming with life.<\/p>\n

\u201cThis is a revolutionary moment,\u201d Dr. Madhusudhan said. \u201cIt\u2019s the first time humanity has seen potential biosignatures on a habitable planet.\u201d<\/p>\n<\/div>\n<\/div>\n

The study was published Wednesday in the Astrophysical Journal. Other researchers called it an exciting, thought-provoking first step to making sense of what\u2019s on K2-18b. But they were reluctant to draw grand conclusions.<\/p>\n

\u201cIt\u2019s not nothing,\u201d said Stephen Schmidt, a planetary scientist at Johns Hopkins University. \u201cIt\u2019s a hint. But we cannot conclude it\u2019s habitable yet.\u201d<\/p>\n
