Astronomers using the European Southern Observatory’s HARPS telescope have studied over 100 nearby red dwarf stars over the last six years. 40 percent of these common stars were observed to wobble, a reaction caused by the gravitational pull of an orbiting planet. Based on this small sample, the astronomers crunched the numbers, and extrapolated the results to cover our entire Galaxy. In other words, instead of guessing, we can calculate that there are 10 billion potentially habitable planets in our Galaxy.
