Kepler’s Kaput, But Exoplanet Discoveries Are Only Just Beginning
NASA’s renowned planet-hunting Kepler space telescope has reached the end of its lifetime. It has run out of fuel and no longer can point itself at stars to determine if planets are in orbit around them (exoplanets). The announcement comes as no surprise. Kepler worked more than twice as long as expected, revolutionizing scientific understanding of planetary system formation along the way. Scientists will continue to study the data it returned and from newer spacecraft.
