Eight New Exoplanets In ‘Goldilocks Zone’ Discovered By NASA’s Kepler Spacecraft
NASA’s Kepler space telescope has found eight alien planets in the “Goldilocks zone”–that is, they orbit their stars at just the right distance to have liquid water, and maybe life.
Two of the newfound planets, dubbed Kepler-438b and Kepler-442b, are being called the most Earth-like exoplanets ever found. Both planets orbit red dwarf stars, which are slightly cooler and smaller than our sun.
“We don’t know for sure whether any of the planets in our sample are truly habitable,” Dr. David Kipping, an astronomer at the Harvard-Smithsonian Center for Astrophysics (CfA) and one of the scientists involved in the discovery, said in a written statement. “All we can say is that they’re promising candidates.”

The planets are just the latest in a long series of exoplanets found by Kepler. Since its 2009 launch, the planet-hunting spacecraft has found 1,004 confirmed planets along with 4,175 planet candidates.
Kepler-438b is located 70 light-years from Earth and orbits its star every 35 days. The CfA astronomers say its diameter is 12 percent bigger than Earth’s. They estimate it has a 70 percent chance of being a —> Read More Here
