Many science fans have heard of the discovery of the planet kepler 452 b.  Out of all the exoplanets, NASA is most excited about the prospects for life on this one.  There is another however which may have similar properties:

A small, rocky planet could host liquid water on its surface, if it also contains a carbon-dioxide atmosphere, researchers say.

The planet, which scientists have dubbed Kepler-62f, has a diameter 40 percent larger than that of Earth, and could contain oceans of water if its atmosphere keeps the planet warm.

“A high carbon-dioxide atmosphere is a reliable way to put liquid water on this planet,” Aomawa Shields, a scientist at the University of California, Los Angeles, who was involved in the new research, said at the Astrobiology Science Conference in Chicago in June.

Let’s check out a cool video on yet another similar planet, kepler 186f in the video on page 2
