Astronomers led by the Carnegie Institute for Science announced on Monday that a huge catalog of observations on nearby stars is now public. By making the dataset available to all, researchers working on the project hope that the data collected at Hawaii’s W.M. Keck Observatory over more than two decades inspires citizen scientists to join the hunt for exoplanets. The public is also encouraged to download and use open-source software and an online tutorial to assist in the hunt. Read more about the announcement.
