      Probably – physicists call these ‘goldilocks’ planets because they are not too hot and not too cold. Sadly they are all trillions of light years away so we cant go and visit to check them out.

      Who knows? There is whats known as the ‘goldilocks’ zone, where everything is just right for supporting life. In the infinate nunber of worlds out there, there has to be more life ours, don’y you think?

      I suspect the answer is yes. Astrophysicists are finding more and more planets as they get better at working out where they are (much dimmer and tiny gravity in comparison with their suns), so it makes sense that a bunch of them would be liveable on.
