Where it is:<\/strong> 150,000 light-years from Earth in the Pictor constellation<\/p>\n When it was shared: <\/strong>March 16, 2026<\/p>\n This gorgeous snap, taken by the Dark Energy Camera (DECam) mounted atop the V\u00edctor M. Blanco 4-meter (13 feet) Telescope in Chile, shows a glistening field of stars inside the dwarf galaxy Pictor II, which is more than 10 billion years old.<\/p>\n But it isn’t just a pretty picture. Nestled inside this image is the star PicII-503, a stellar furnace so ancient that it’s classed as a Population II, or second-generation, star, making it among the oldest stars in the universe.<\/p>\n <\/p>\n Population II stars formed when the cosmos was young and stars had yet to fuse heavier elements into existence, meaning they are composed primarily of hydrogen and helium. This means that PicII-503 has roughly only 1-40,000th of the iron contained within our much younger sun.<\/p>\n Article continues below <\/p>\n You may like<\/p>\n But what the star lacks in iron it makes up for in carbon. Like many Pop II stars, PicII-503 is unusually rich in the stuff, having a carbon-to-iron ratio that’s more than 1,500 times the ratio in the sun, researchers said in a statement<\/a>.<\/p>\n \n PicII-503’s location inside Pictor II (Image credit: CTIO\/NOIRLab\/DOE\/NSF\/AURA Image processing: Image Processing: T.A. Rector (University of Alaska Anchorage\/NSF NOIRLab), M. Zamani & D. de Martin (NSF NOIRLab) Acknowledgment: PI: Anirudh Chiti, Alex Drlica-Wagner)<\/p>\n Astronomers have proposed many theories why this may be the case but because many Pop II stars are spotted after they’ve migrated away from their birthplaces, these suggestions have been hard to verify.<\/p>\n But PicII-503 is still located within its primordial dwarf galaxy, so astronomers acted as “stellar archeologists,” using the star\u2019s composition to test their theories. The star\u2019s carbon-rich makeup lends credence to an idea that, during the violent supernova explosion at the end of a star\u2019s life, lightweight carbon in the star\u2019s outer shell is flung farther away than other elements.<\/p>\n That could also explain why carbon ends up everywhere in the universe, making it an extremely suitable element to act as the key building block for life<\/a>.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":"Quick Facts What it is: Star PicII-503 inside the Pictor II dwarf galaxy Where it is: 150,000 light-years…\n","protected":false},"author":3,"featured_media":674080,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[159,783,67,132,68],"class_list":{"0":"post-674079","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-science","9":"tag-space","10":"tag-united-states","11":"tag-unitedstates","12":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/116273688530414560","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/674079","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=674079"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/674079\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/674080"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=674079"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=674079"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=674079"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"A](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2026\/03\/FnN7BYDAdN9G4U73E6njRU.jpg\")
