Astronomers using NASA’s Kepler Space Telescope have discovered the most earth-like planet yet circling a star 600 light years away.  The planet is the right distance from its sun, but 2.4 times larger than Earth so the astronomers do not know yet if it is rocky or gaseous.  Read more in the Reuter’s story Planet found orbiting habitable zone of sun-like star.

It will be a long time before we can visit though.  Even at the cruising speed of 38,000 miles per hour (61,155 K/hr) of Voyager 1 (per Wikipedia), our farthest space satellite from Earth, it would take 10.8 million years to travel 600 light years.
