Jon Jenkins, Kepler data analysis lead at NASA's Ames Research Center, says on discovery of Kepler-452b: 'It's awe-inspiring to consider that this planet has spent 6 billion years in the habitable zone of its star; longer than Earth. That's substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet.' - @NASAKepler http://www.nasa.gov/press-release/nasa-kepler-mission-discovers-bigger-older-cousin-to-earth/
