said O&#8217;Connor, who used infrared instruments on the Gemini South telescope in Chile to take fresh observations early Friday.<\/p>\n<p>&#8220;Something this bright, this nearby, is really a once-in-a-century event,&#8221; he added.<\/p>\n<p>Gamma-ray research first began in the 1960s when US satellites designed to detect whether the Soviet Union was detonating bombs in space ending up finding such bursts originating from outside the Milky Way. <\/p>\n<p>&#8220;Gamma-ray bursts in <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a> release the same amount of energy that our Sun produces over its entire lifetime in the span of a few seconds\u2014and this event is the brightest gamma ray burst,&#8221; said O&#8217;Connor.<\/p>\n<p>This gamma-ray burst, known as GRB 221009A, was first spotted by telescopes including NASA&#8217;s Fermi Gamma-ray Space Telescope, Neil Gehrels Swift Observatory, and Wind spacecraft on Sunday morning Eastern time. <\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/this-picture-provided-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/2022\/this-picture-provided-1.jpg\" data-sub-html=\"This picture provided by Noirlab on October 14, 2022 shows record-breaking Gamma-Ray bursting caught with Gemini South in Chile.\">\n<figure class=\"article-img text-center\">\n            <img decoding=\"async\" src=\"https:\/\/scx1.b-cdn.net\/csz\/news\/800a\/2022\/this-picture-provided-1.jpg\" alt=\"This picture provided by Noirlab on October 14, 2022 shows record-breaking Gamma-Ray bursting caught with Gemini South in Chile\" title=\"This picture provided by Noirlab on October 14, 2022 shows record-breaking Gamma-Ray bursting caught with Gemini South in Chile.\"\/><figcaption class=\"text-left text-darken text-truncate text-low-up mt-3\">\n                This picture provided by Noirlab on October 14, 2022 shows record-breaking Gamma-Ray bursting caught with Gemini South in Chile.<br \/>\n            <\/figcaption><\/figure>\n<\/p><\/div>\n<\/div>\n<p><b>1.9 billion-year-old movie<\/b><\/p>\n<p>It originated from the direction of the constellation Sagitta, and traveled an estimated 1.9 billion years to reach Earth\u2014less than the current distance of its starting point, because the universe is expanding.<\/p>\n<p>Observing the event now is like watching a 1.9 billion-year-old recording of those events unfold before us, giving astronomers a rare opportunity to glean new insights into things like black hole formation.<\/p>\n<p>&#8220;That&#8217;s what makes this sort of <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">science<\/a> so addictive\u2014you get this adrenaline rush when these things h<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp;
