It has been known for many years that worlds like Earth, with oceans that lie on their surface, must reside within a narrow range of distances from their stars to maintain the temperatures that preserve those oceans. However, IWOWs are found over a much wider range of distances from their stars. This greatly expands the number of habitable worlds likely to exist across the galaxy.

You don't believe how many times I have tried to explain this to couple of my cousins and friends but none of them seem to believe or even have a open mind about the possibility of another habitable planets.
