The answer to The Question of the Ages


Kepler to be launched in hours. If it makes it and works for three years, we will know which of 100,000 Sunlike stars has Earthlike planets. Actually, information will probably start leaking out later this year.

A current guess is that nearly every Sunlike star has at least one planet or moon that could support life. Our solar system alone used to have at least three. Venus and Mars had oceans like Earth billions of years ago. Even now, it is likely there are at least bacteria all over Mars and the moons of Jupiter and Saturn, and possibly the upper atmosphere of Venus and in the subsurface of the larger asteroids. And that is just for life as we know it...
