The search for extraterrestrial life zeroed in a bit today as NASA announced that its unmanned Kepler Space Telescope detected the most Earth-like planet yet found beyond the Solar System. Named Kepler-186f, the new planet orbits a red dwarf star about 500 light years away from Earth in the constellation of Cygnus, is only 10 percent larger than our planet, and could have liquid water, which is essential for life as we know it.
