NASA's Spitzer telescope confirms a new neighbor in the form of a larger-than-Earth rocky planet outside our solar system.
There's reason to believe that other planets might be better for supporting life as we know it, and they might not even be that far off, cosmically speaking.
Rallying back from a mechanical failure, the telescope helps confirm the existence of an exoplanet 2.5 times the diameter of Planet Earth.
The planets in the habitable zone orbiting a star may be suitable for liquid water and supporting life.
You may think this planet is overpopulated or you may just be sick of the partisan politics. In either case, HD 40307g is an attractive getaway.
