Water has been detected in the atmosphere of an extrasolar planet, but a team of Harvard researchers hesitates to conclude that this represents a step in the process to find life beyond Earth...
Lowell Observatory Astronomer Travis Barman made the discovery by comparing theoretical models that he had developed with previously collected data on HD209458b, a large, gaseous planet located 150 light years away from Earth...
When asked about Charbonneau’s criticism, Barman cited similarities between Charbonneau’s landmark findings and his own. “David used the exact same method, exact same instrument, exact same telescope, the exact same planet, and the exact same uncertainty in measurements to discover the existence of extrasolar planets,” he said.

...findings show strong evidence for water’s presence in HD209458b’s atmosphere,” Barman said. “Now that we know that water vapor exists in the atmosphere of one extrasolar planet, it’s probably safe to say that other extrasolar planets also contain water vapor...
...Charbonneau led a team in making the first detection of an atmosphere on an extrasolar planet, using a technique similar to transmission spectroscopy...
