NASA discovers Earth-sized planet that could be habitable
"This is the first definitive Earth-sized planet found in the habitable zone," said Elisa Quintana of the Search for Extraterrestrial Intelligence Institute at NASA. "Finding such planets is a primary goal of the Kepler space telescope."
The instituted 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."
