Astronomers have been observing the sky for thousands of years. Early on, the knowledge recorded with the naked eye was passed on orally. After writing was developed, observations could be recorded and compared. Over time, astronomers developed telescopes that allowed them to look much further into the universe than before, to make more observations and thus collect successively more data. Today, we also have other methods to study the universe. Radio astronomy in particular has been enormously successful, allowing astronomers to discover signals dating back to the Big Bang, radio waves that still fill the universe today. While telescopes got bigger and better, radio telescopes can today collect more data than all of humanity did before. For their discoveries to keep pace with this volume of data, new methods need to be developed.  This is one of the Cluster's goals.
