12.05.11 – This artist’s conception illustrates Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA’s Kepler mission has confirmed to orbit in a star’s habitable zone – the region around a star where liquid water, a requirement for life on Earth, could persist.

2017年11月15日 · Kepler-22b is the first extra-solar planet, or exoplanet, that the Kepler Space Telescope found in the habitable zone of its star. It is thought to be a promising spot to search for life. But at...
