Four light years away, a planet may be hospitable to life
Scientists have discovered a potentially habitable new world, a mere four light years away from Earth. They call the planet “Proxima b,” and it may feature characteristics that are just right for human life. Nonetheless, it has some major differences from Earth -- a year on the planet lasts only 11 days. Hari Sreenivasan speaks with science correspondent Miles O'Brien for background.
