A team of astronomers from the National Astronomical Observatory of Japan (NAOJ) has implemented artificial intelligence (AI) to ultra-wide field-of-view images of the distant Universe captured by the Subaru Telescope, and have scored very high accuracy for locating and classifying spiral galaxies in those images. Due to its high sensitivity, as many as 560,000 galaxies have been detected in the images. AI classified about 80,000 of them as the spiral, leaving about 480,000 as non-spiral galaxies.  It would be quite challenging to visually process this large number of galaxies one by one with human eyes for morphological classification.  This promising method, in collaboration with citizen science, is expected to yield further developments in the future.
