NASA's Kepler Space Telescope, which launched in 2009, was officially retired in October 2018 after running out of fuel. Over its career, the telescope discovered 2,650 exoplanets and provided huge amounts of data that scientists are still exploring. Here, NASA provides a wealth of information intended primarily for researchers, though space enthusiasts may also find it of interest. The homepage features Kepler news for scientists, such as data release notes and white papers. The missions section contains overviews of the Kepler telescope's missions, as well as information about the telescope itself and the science and publications the telescope has made possible. In the K2 observing section, readers will find detailed information and notes about the second phase of the Kepler telescope's career, K2. Those interested in the data gathered by the telescope should check out the data analysis section, where they will find a meticulous overview of the missions' assorted data products; a thorough explanation of their data processing pipeline; and links to the official data archives, associated software tools, and papers helpful for working with the Kepler and K2 data.
