Did you know NASA announced on Thursday July 23, 2015 that there is a planet called Kepler-452b that seems to be similar to that of Earth, but older?

They believe that this planet once contained water and the possible lack of water can be the future for our own planet billions of years from now. For more information, click on the links below.
