After several months’ worth of review and testing, the team operating the Kepler Space Telescope has opted to close its efforts to make Kepler fully operational again. This follows the loss of one of the crucial components that controls the alien planet-hunting spacecraft. In an Aug. 15 teleconference, Charles Sobeck, […]

The Kepler space telescope has been nothing short of incredible, revolutionizing our understanding of exoplanets and showing just how common and diverse they really are (as the saying goes, truth is stranger than fiction). Recently, however, additional mechanical […]

What Comes After Kepler?
