    The MEarth-South telescope array, located on Cerro Tololo in Chile, searches for planets by monitoring the brightness of nearby small stars. This photograph shows the array, comprising eight 40cm telescopes, at twilight.

GJ 1132b is only 39 light years away. That's nearly a neighbor on the cosmic scale. It may be the closest Earth-size planet we've discovered. However, it most likely resembles Venus as far as surface temperatures. Scientists believe it may be too hot to support life, but cool enough to hold an atmosphere.
