How many exoplanets are in the cosmos and what can they tell us about planetary formation and evolution? This is what a recent study published in The Astronomical Journal hopes to address as an ...

This discovery was made by two of NASA’s most celebrated telescopes. This illustration provided by Dan Durda shows the exoplanet Kepler-1625b with a hypothesized moon. On Thursday, Oct. 4, 2018, two ...

As if further evidence of its resolving power was needed, NASA’s Kepler planet finder has located a planet circling a star similar to the Sun that is only slightly larger than the Moon. Called ...

Space-watchers saw the handwriting on the wall months ago, but now it’s official: NASA’s Kepler spacecraft, by far the most successful planet-hunting telescope in history, isn’t coming back. Engineers ...
