GALAXY CRUISE: Accessible Big Data of the Subaru Telescope for Citizen Astronomers

Abstract

AbstractThe Universe is full of galaxies of various shapes; some galaxies have spiral arms and others don’t. Why do galaxies show such diversity? How were galaxies formed and evolved? Galaxies are thought to grow by interacting and merging with other galaxies, and the galaxy mergers may be the key process creating the variety. GALAXY CRUISE is the first citizen science project conducted by National Astronomical Observatory of Japan (NAOJ) to unlock galaxies’ secrets using the big observational data. We made the superior quality big data taken by the Subaru Telescope accessible to the public and invited them to participate in data classification. Here we report how we designed the website and its first-year progress.
