We have always been interested in the question of life in the universe. One way of answering this question is to estimate how many life bearing planets might exist. Our approach to studying his question has been long based on the assumption that we a star like ours. It should be of average brightness, average mass, and on its own. However most stars are part of binary system – i.e., two stars orbiting each other, and we have always though that such binary system would be too unstable to have planets.
Of course data has the tendency to upset such assumptions, and here is a great example of this. New data from the Kepler mission has found a nice stable planet with two parent Suns. How will this affect out estimates of the number of potential life bearing planets. Well, if confirmed, this estimate will at least double and probably even triple. Maybe the next series of telescope currently being planned will even see these planets.
