Scientists have been on a search across the universe for Earth-like planets that could sustain life since the planet-finding Kepler spacecraft was launched on March 7, 2009.
Today, according to the New York Times, they've found the two most promising worlds yet: a pair of planets orbiting a star, now named Kepler 62, in the constellation Lyra.
The new discoveries fall into the so-called "Goldilocks Zone," with temperatures able to sustain lukewarm water, which, as far as we know, is an important ingredient to life.
Not only that, but the planets are also fairly large, which increases the possibility of life. Previously most of the "Goldilocks" planets discovered have been small, nestled close to "red dwarf" stars.
The planets, 1200 light-years from our own, are likely comprised of rock, with oceans surrounding it. They are being named Kepler 62f, which is about 50% larger than Earth, and Kepler 62e, about 60% larger.
Scientists are longing to find "Earth 2.0," which perfectly replicates the conditions in which life on our planet has occurred.
Finding a life-sustaining planet probably doesn't mean that aliens will be knocking at our door any time soon, but it's still pretty cool.
