Researchers claimed today that the Milky Way Galaxy could contain a staggering 60-billion planets capable of supporting life, based on data from NASA’s Kepler spacecraft. They predict that there should be at least two Earth-size planet in the habitable zone of each red dwarf, the most common type of star. Continue reading for two videos and more information.
Nicolas Cowan, another author of the study and a postdoctoral fellow at Northwestern University, said: ‘If you’re orbiting around a low mass or dwarf star, you have to orbit about once a month or once every two months to receive the same amount of sunlight that we receive from the sun.’
As the orbit of these habitable planets around a red dwarf is tight, they are tidally locked, so that one side of the planet always faces the star. Therefore anything living on one of these planets would enjoy continual daylight.
