Elisa Quintana of the Search for Extraterrestrial Intelligence Institute at NASA stated:
"This is the first definitive Earth-sized planet found in the habitable zone.
Finding such planets is a primary goal of the Kepler space telescope."
The institute stated:
"This discovery not only proves the existence of worlds that might be similar to our own, but will undoubtedly shape future investigations of exoplanets that could have terrestial surface environments."
