Worlds without end: The existence of a Kepler-found earth-sized planet in the habitable zone has been confirmed.
The newfound planet, called Kepler-186f, was first spotted by NASA’s Kepler space telescope and circles a dim red dwarf star about 490 light-years from Earth. While the host star is dimmer than Earth’s sun and the planet is slightly bigger than Earth, the positioning of the alien world coupled with its size suggests that Kepler-186f could have water on its surface, scientists say.
In this new work, the Keck and Gemini ground-based telescopes confirmed Kepler’s discovery.
