Over de aflevering
At the turn of the century just a couple planets around other stars had been discovered. Now more than 4000 have been found. Lisa Kaltenegger specializes in finding the fingerprint of life in the faint light that reaches us from those stars and planets.
In this Space Cowboys episode we discuss with Lisa how exoplanets are discovered, what changes life can make to the chemical makeup of an atmosphere and how you can detect those changes from lightyears away. The telescopes that are needed to do this, the James Webb Space Telescope and the Extremely Large Telescope, are expected to come into service in the near future.
