JWST Will Provide Capability to Search for Biomarkers on Earth-like Worlds

Written by Nancy Atkinson

Does another Earth exist somewhere in our galaxy? With the recent lauch of the Kepler spacecraft, astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit.

But once that search succeeds, the next questions driving research will be: Is that planet habitable? Does it have an Earth-like atmosphere? Answering those questions will not be easy.

But the telescope up for the task is the James Webb Space Telescope (JWST), set for a planned launch in 2013.

Two researchers recently examined the ability of JWST to characterize the atmospheres of hypothetical Earth-like planets, and found this is the telescope that would be able to detect certain gases called biomarkers, such as ozone and methane, for close Earth-size worlds.

See our related article: Q&A with Dr. John Mather on JWST.
