The Prime Focus Spectrograph, a cutting-edge multi-object spectrograph on the Subaru Telescope developed by the international collaboration led by Kavli IPMU, is the best instrument to discover ancient stars in the outer regions of the Milky Way far beyond the solar neighbourhood,\u201d said Visiting Associate Scientist and National Astronomical Observatory of Japan Assistant Professor, Miho Ishigaki.<\/span>\u00a0<\/span><\/p>\nFuture uses of the team\u2019s algorithm <\/span>\u00a0<\/span><\/h3>\nNow, the team hopes that their algorithm can be used to make the most of diverse chemical fingerprints in metal-poor stars discovered by the Prime Focus Spectrograph.<\/span>\u00a0<\/span><\/p>\n\u201cThe theory tells us that the first stars should be more massive than the Sun. The natural expectation was that the first star was born in a gas cloud containing a mass million times more than the Sun. However, our new finding strongly suggests that the first stars were not born alone, but instead formed as a part of a star cluster or a binary or multiple-star system. This also means that we can expect gravitational waves from the first binary stars soon after the Big Bang, which could be detected in future missions in space or on the Moon,\u201d concluded Kobayashi.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"Artificial Intelligence has found that the very first stars in the Universe were born in clusters rather than as isolated stars. <\/p>\n","protected":false},"author":18,"featured_media":31177,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[771],"tags":[570,818,3477],"acf":[],"yoast_head":"\n
