A team of astronomers announced April 17, 2014, that they have discovered the first Earth-size planet orbiting a star in the so-called “habitable zone” — the distance from a star where liquid water might pool on the surface. That doesn’t mean this planet has life on it, says Thomas Barclay, a scientist at the Bay Area Environmental Research Institute at Ames and a co-author of a paper on the planet, called Kepler-186f. He says the planet can be thought of as an “Earth-cousin rather than an Earth-twin. It has many properties that resemble Earth.” The planet was discovered by NASA’s Kepler Space Telescope. It’s located about 500 light-years from Earth in the constellation Cygnus. The picture above is an artist’s concept of what it might look like.
