Content: To date, Kepler has found over 2,300 confirmed exoplanets and has over 4,000 candidates to verify. Kepler particularly focused on finding planets orbiting their host star in a region known as the habitable zone – which means that the planet is the right temperature to have liquid water on its surface. Currently scientists have only one example of life and that’s on Earth. Every life-form on the Earth requires liquid water to survive so it makes sense to search for water elsewhere if they want to find alien life that would be familiar to us. The Kepler space telescope also studies the atmospheres of these planets – looking for any organic molecules or water signatures. Kepler and K2 Missions
With the upcoming launch of the massive James Webb Space Telescope, astronomers be able to study these alien atmospheres with even greater precision. James Webb Space Telescope (WEBB/JWST) NASA
* With so many potential life bearing planets out there, why have we not been able to contact or even discover any of them? Or, why haven’t any of them contacted us? The answer to this lies in the Fermi Paradox. Back in the 1950s, physicist Enrico Fermi (1901-1954) the famous American physicist noted, that if there are intelligent civilisations out there, then inevitably they should travel and spread across the stars, given enough time.
