Episode: 63E-75-Will Space Aliens Discover Us By Our Pollution
Description: When a distant planet passes in front of its star some of the star's radiation goes through the planet's atmosphere. The pattern of colors or wavelengths which are present and missing tells us what is in the planet's atmosphere. The NASA Kepler Spacecraft has discovered more than a half dozen Earth like planets which pass between their star and the Earth. It appears likely that a way to discover pseudo intelligent life in the Universe is to search for pollution in their planet's atmosphere.
