NASA is stopping at nothing to find out if we're really alone in the universe.
Last year, 24 so-called "super habitable" exoplanets out of 4,500 were spotted by a team from Washington State University. These planets were called "super habitable" because the researchers identified them to be a little bigger and warmer, slightly older, and wetter than the Earth. According to them, these factors combined could make for a world that's actually cooler and more conducive for complex life forms to evolve.
These planets, however, can never be visually confirmed because they're too far away. On average, they're 100 light years away from the Earth. For the uninitiated, a light year is the distance that light (the fastest thing in the universe) travels within a year. That entire distance? 6 trillion miles (9 trillion kilometers), according to SpacePlace.
One planet, though, might've been the first-ever one to actually be photographed: Proxima C. In a paper published in the journal "Astronomy and Astrophysics," the team that was studying Proxima C made this claim.
For now, the hunt for life elsewhere in the universe goes on, and NASA, along with other space agencies, will be leading all efforts.
