Searching for Alien Life on other Planets Documentary - The Science of Exoplanet Discovery

Since the launch of NASA’s Kepler space telescope in 2009, scientists have uncovered thousands of distant exoplanets in the deep depths of space.

Scientists in California and Australia are now hoping to expand upon Kepler’s work with 121 planets potentially hosting life-supporting moons.

The key to finding a habitable exoplanet or moon is to find the stellar bodies within the so-called Goldilocks zone.

These are the ideal hotspots within a solar system where a planet’s atmospherics are neither too hot nor too cold for liquid water to exist.
