The star has\nthe shortened name of SM0313 and it was born 13.6 billion years ago, pretty\nmuch 100 or 200 million years after the Big Bang took place. It is assumed that\nSM0313 can be a Population II star that was made from the remains of one of the\nvery first supernovae of the universe. SM0313 was first discovered by the\nAustralian National University&#8217;s Siding Spring Observatory&#8217;s SkyMapper\nTelescope, which is working on mapping out a billion stars, galaxies, and\nasteroids in the southern parts of the skies. <\/p>\n\n\n\n<p>Then the Magellan Telescopes in Chile came up with some\nhigh-resolution images. With these images, the astronomers detected something\nquite odd. They noticed that SM0313 has very little iron in its\ncomposition, i.e., under one ten-millionth of the iron which is found in the\nSun of the Earth&#8217;s Solar System. <\/p>\n\n\n\n<p>SM0313 is more or less pure hydrogen and helium, with virtually no\nheavy elements in it. It also contains some carbon, and light metals such as\ncalcium, lithium, and magnesium. This has surprised the astronomers, as they\nused to think that the first-generation supernovae generated a lot of iron. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Oldest Galaxy<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" data-src=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-1024x576.jpg\" alt=\"\" class=\"wp-image-347505 lazyload\" data-srcset=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy.jpg 1024w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-600x338.jpg 600w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-300x169.jpg 300w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-768x432.jpg 768w\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/576;\" \/><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-1024x576.jpg\" alt=\"\" class=\"wp-image-347505\" srcset=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy.jpg 1024w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-600x338.jpg 600w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-300x169.jpg 300w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/First-Galaxy-768x432.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/noscript><\/figure><\/div>\n\n\n\n<p>At the moment, GN-z11 is the oldest and most distant known galaxy\nin the observable universe. It is a high redshift galaxy discovered in the\nconstellation Ursa Major. This galaxy has a spectroscopic redshift of z =\n11.09, which relates to a proper distance of nearly 32 billion light-years.<\/p>\n\n\n\n<p>The name of the galaxy has been derived from its location in the\nGOODS-North field of galaxies and its high cosmological redshift number (GN +\nz11). It is believed that as GN-z11 existed 13.4 billion years ago, just about\n400 million years after the Big Bang took place. <\/p>\n\n\n\n<p>The research team employed Hubble&#8217;s Wide Field Camera 3 to find\nthe distance to GN-z11 spectroscopically, by breaking the light into its\ncomponent colors to ascertain the redshift which was caused by the expansion of\nthe universe. As compared to the Milky Way galaxy, GN-z11 is \u200b1\u204425th of the\ngalaxy size, has 1% of the mass, and it is creating new stars almost twenty\ntimes faster than the Milky Way Galaxy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Oldest Light<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"350\" data-src=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light.jpg\" alt=\"\" class=\"wp-image-347504 lazyload\" data-srcset=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light.jpg 750w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light-600x280.jpg 600w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light-300x140.jpg 300w\" data-sizes=\"(max-width: 750px) 100vw, 750px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 750px; --smush-placeholder-aspect-ratio: 750\/350;\" \/><noscript><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"350\" src=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light.jpg\" alt=\"\" class=\"wp-image-347504\" srcset=\"https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light.jpg 750w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light-600x280.jpg 600w, https:\/\/dailyjag.com\/wp-content\/uploads\/2019\/03\/Oldest-Light-300x140.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/noscript><\/figure><\/div>\n\n\n\n<p>While studying a distant quasar, scientists have come across some\nof the oldest light in the universe.
