Scientists discover another Earth-like planet

Earth and Kepler-186F
NASA's Kepler Space Telescope discovered an Earth-like planet orbiting a start within the habitable zone of our galaxy, Kepler-186f, approximately 500 light years away from Earth in the Cygnus constellation.  This habitable zone is the region around a star where planetary-mass objects with sufficient atmospheric pressure can support liquid water at their surfaces.  This discovery is rated the first Earth-sized planet to be found in the habitable zone of another star.

In addition to this discovery, there are four other planets that orbit a start near this system.  If the nearby star to this planet is similar to our sun, then the probability of sustaining life on this planet rises greatly.  Kepler-186f orbits its star once every 130 days.

"We know of just one planet where life exists - Earth. When we search for life outside our solar system we focus on finding planets with characteristics that mimic that of Earth," Elisa Quintana, research scientist at the SETI Institute at NASA's Ames Research Center, stated. "Finding a habitable zone planet comparable to Earth in size is a major step forward."
