NASA discover Earth's twin 1,400 light-years away

The Kepler mission has found the first near-Earth-size planet - called Kepler-452b - in the "habitable zone" around a G2 star much like our own sun. Kepler-452b is 60 percent larger in diameter than Earth and is considered a super-Earth-size planet. Its 385-day orbit is only 5 percent longer as the planet is 5 percent farther from its parent star. That star, Kepler-452, is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 percent brighter and has a diameter 10 percent larger. The Kepler-452 system is located 1,400 light-years away in the constellation Cygnus.

"We can think of Kepler-452b as an older, bigger cousin to Earth, providing an opportunity to understand and reflect upon Earth's evolving environment," said Jenkins. "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."

Not a great read... Over and over they speculate about this theory or that, then walk it back with "but that’s assuming" xyz...

See them keep repeat that pattern reminded me of something:
