Finding life near other stars

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. ==LINKS== Lisa Kaltenegger Carl Sagan Institute Colorful Life Form Catalog ==VIDEO VERSION== Patience... ==CREDITS== Space Cowboys is made by Tyse Roes and Herbert Blankesteijn in collaboration with BNR Nieuwsradio in Amsterdam, The Netherlands.
