Ancient Aliens season 8 ep.6 – The Other Earth: Billions of dollars have been spent in our quest to find an “other Earth.” Since the launch of the Kepler Telescope in 2009, scientists have identified thousands of planets capable of supporting life. Is it possible that this discovery finally answers the age-old question: “Are we alone in the universe?” Could it be that just as we seek out other habitable planets, advanced extraterrestrials from distant galaxies did the same with Earth in the remote past?
Throughout world mythologies, there are tales of beings from the stars coming down to Earth. The Dogon tribe in Africa believes their gods came from the Sirius star system. The Maya associated their gods with the Pleiades star cluster. And according to the Hopi tradition, life itself was seeded by celestial beings. Ancient Astronaut theorists propose that not only has our planet been visited by extraterrestrials, but that they are responsible for our very existence.

Kepler space telescope
The Kepler space telescope is a deactivated space telescope launched by NASA to discover Earth-size planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched on March 7, 2009, into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine years of operation, the telescope’s reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018.
Designed to survey a portion of Earth’s region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and estimate how many of the billions of stars in the Milky Way have such planets, Kepler’s sole scientific instrument is a photometer that continually monitored the brightness of approximately 150,000 main sequence stars in a fixed field of view. These data are transmitted to Earth, then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star. Only planets whose orbits are seen edge-on from Earth can be detected. During its over nine and a half years of service, Kepler observed 530,506 stars and detected 2,662 planets.
