Lots and Lots of Alien Planets?
NASA's space telescope found lots of planets that could harbor life- 54 of them. This is probably like the one NASA found a few months ago, which was in the so-called "Goldilocks zone" which isn't too far or too close to the star it's orbiting, and so might have liquid water and a temperature that's not too cold or too hot.
But still, Kepler's only covered one-400th of the whole galaxy, so there might be...
54 times 400=21,600 planets could have liquid water!
And in those 21,600, how much would harbor life...?
