When NASA launched the Kepler Space Telescope in 2009, its mission was clear: to explore the stars and uncover distant ...

They’re still looking for more in the Kepler data -- but after finding the planet known as Kepler-186f, “we can infer that other ones are likely to exist. And that’s going to be the job of ...

While Kepler’s progress is encouraging, some of the hype around recent discoveries may have been premature. The two Earth-size planets, Kepler-20e and Kepler-20f, orbit too close to their sun ...

A star known as Kepler-69, located some 2,700 light years away, is 93 percent the size of the sun and 80 percent as luminous. It hosts two confirmed planets, Kepler-69c and Kepler-69b.

The nearer planet, Kepler-69b, is twice the size of Earth, but is so close that it’s year is only 13 days and too hot. However, Kepler-69c is only 70 percent larger and orbits at a period of 242 ...

The new planet - named Kepler-22b - has key aspects it shares with Earth. It circles a star that could be the twin of our sun and at just about the same distance. The planet's year of 290 days is ...

Two of its five planets -- Kepler-62e and Kepler-62f -- are so-called super-Earths with a radius of 1.6 and 1.4 times that of Earth respectively. Kepler-62e orbits its sun every 122 days while ...

While the Kepler mission has found 69 exoplanets that orbit in the habitable zone, Kepler-186f is the closest to Earth’s size. The planet’s composition, whether it is a rocky planet like Earth ...

Kepler-78b: This scorched planet is more like Earth than you think. By Amina Khan . Oct. 30, 2013 7:58 PM PT . ... extrasolar planets of Earth-like composition are not rare,” Deming said.

Kepler results show 22 percent of sun-like stars harbor planets similar to Earth in their habitable zones -- meaning there are billions of Earth-like worlds in the Milky Way.

The Kepler space telescope's latest and most complete planet catalog adds 219 new candidates, including one that could be a close cousin to Earth. NASA's Kepler reveals 10 new potentially Earth ...

This artist's concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The habitable ...
