Including potential planets, the total count stood at 4,034. Kepler also came through on its mission to find a planet approximately the size of Earth in the habitable region of a star.

About 18,000 new species are discovered every year. Also, researchers have observed that diversity of land animals increases as they get smaller, giving them more reason to continue to search for more un-cataloged new species. In fact this year alone has seen some pretty remarkable new discoveries already.
