The Einstein Probe satellite, built by the Chinese Academy of Sciences with the European Space Agency, recorded a brief pulse of these X-rays and labeled the event EP260321a. Ground telescopes responded within an hour and quickly found a supernova growing brighter by the minute. Researchers later named the explosion SN 2026gzf.<\/p>\n<p><span id=\"more-252872\"\/><br \/><iframe title=\"DECam images of supernova SN 2026gzf\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/7Oh_nL5FCTI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><noscript><iframe title=\"DECam images of supernova SN 2026gzf\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/7Oh_nL5FCTI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/noscript><br \/>\nTwo astronomy teams were diving into the same region, utilizing a range of NSF NOIRLab resources. One, led by Brendan O\u2019Connor of Carnegie Mellon University, and the other by Jillian Rastinejad of the University of Maryland, reached the same conclusion after evaluating the data. Their early observations suggested that the explosion began with a shock breakout. A shock breakout occurs when an immensely powerful shockwave from a collapsing core smashes through the star\u2019s surface, allowing the supernova to shine. This isn\u2019t uncommon in supernovae, but they\u2019re difficult to detect because they only endure a few seconds to a few hours. To put it in context, there has only been one validated x-ray shock in the last 20 years, and scientists were certain this was the real deal. EP260321a is a once-in-a-lifetime scientific discovery.<\/p>\n<div class=\"aawp\">\n<div class=\"aawp-product aawp-product--horizontal\" data-aawp-product-asin=\"B0CRWGX5NH\" data-aawp-product-id=\"250066\" data-aawp-tracking-id=\"tec02e-20\" data-aawp-product-title=\"LEGO Icons NASA Artemis Space Launch System - DIY Rocket Model Building Set for Adults Ages 18+ - Gifts for Birthdays - Unique Bedroom Decoration for Space &amp; NASA Lovers - 10341\">\n<div class=\"aawp-product__thumb\">\n<p>            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/51wSP6c2joL._SL160_.jpg\" alt=\"LEGO Icons NASA Artemis Space Launch System - DIY Rocket Model Building Set for Adults, Ages 18+ - Gifts...\"\/><\/p><\/div>\n<div class=\"aawp-product__content\">\n<p>            LEGO Icons NASA Artemis Space Launch System &#8211; DIY Rocket Model Building Set for Adults, Ages 18+ &#8211; Gifts&#8230;        <\/p>\n<div class=\"aawp-product__description\">\n<ul>\n<li>NASA rocket model kit \u2013 Launch into a creative project with the LEGO Icons NASA Artemis Space Launch System model building project for adult space&#8230;<\/li>\n<li>What\u2019s in the box? \u2013 This creative building set includes everything you need to craft a multistage rocket with 2 solid-fuel boosters, an Orion&#8230;<\/li>\n<li>Features and Functions \u2013 This NASA-themed rocket model features retractable launch tower umbilicals, rocket support and crew bridge, detachable&#8230;<\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<p>\n<iframe title=\"Zoom into supernova SN 2026gzf\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/ItGs4MX37f8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><noscript><iframe title=\"Zoom into supernova SN 2026gzf\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/ItGs4MX37f8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/noscript><br \/>\nPeople looking over the data discovered that SN 2026gzf is a broad-lined Type Ic supernova. These explosions are typically extremely intense, resulting in streams of material that travel at the speed of light. They are frequently accompanied by a gamma ray burst, which is one of the most tremendous energy outputs ever observed. Unfortunately, in this case, the teams were unable to identify a gamma ray burst, its high-speed jet, or even the afterglow. O\u2019Connor hypothesized that the jet was likely muted by the star\u2019s surface or surrounding material before breaking loose. Even though the explosion was quite intense, the resulting x-ray flare was exceptionally mild for something linked with a broad-lined Type Ic supernova.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/08\/05111355\/soft-x-ray-flash-supernova-sn-2026gzf-1.jpg\" alt=\"Soft X-Ray Flash Supernova SN 2026gzf\" width=\"1280\" height=\"747\"\/><br \/>Over a decade earlier, the Dark Energy Camera on the V\u00edctor M Blanco 4-meter Telescope captured images of a blue source in the same position. That was intriguing since it implied that the star was already fairly active before collapsing. DECam later captured several further photographs, revealing that the supernova was becoming increasingly strong. Meanwhile, the NSF-DOE Vera C. Rubin Observatory produced multiband observations of the event in its COSMOS Deep Meiling field, revealing information on the star\u2019s behavior before to the explosion. The DESI on the Nicholas U. Mayall 4-meter Telescope captured a succession of spectra that helped determine the type of supernova and tracked the light as it spread.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/08\/05111405\/soft-x-ray-flash-supernova-sn-2026gzf-2.jpg\" alt=\"Soft X-Ray Flash Supernova SN 2026gzf\" width=\"1280\" height=\"1530\"\/><br \/>Rastinejad\u2019s team employed both Gemini telescopes, as well as the Gemini Multi-Object Spectrographs and the Goodman spectrograph on the SOAR 4.1-meter Telescope, to gain a comprehensive look at the event at all wavelengths. They examined the data and concluded that the star that went supernova was a Wolf-Rayet star. Born with nearly twenty times the mass of the sun, it had already depleted all of its hydrogen and blown off all of its helium in a series of frenzied explosions. The residual core was largely carbon and oxygen, and the mass loss episodes left behind a variety of material shells: a small tight one near to the star that provided the soft X-ray signal, and a larger one further away that created the supernova\u2019s visible brightness.<br \/><span>[Source]<\/span><\/p>\n<\/p><\/div>\n<p> Rare Soft X-Ray Flash Gives Scientists a Clear View of a Star\u2019s First Explosive Moment<br \/>\n<br \/>#Rare #Soft #XRay #Flash #Scientists #Clear #View #Stars #Explosive #Moment<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Soft X-rays from a galaxy about 500 million light-years away triggered an urgent worldwide search&#8230;<\/p>\n","protected":false},"author":1,"featured_media":19347,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[1982,9346,6009,1234,686,5111,2338,651,2888,12660],"class_list":["post-19346","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tech","tag-clear","tag-explosive","tag-flash","tag-moment","tag-rare","tag-scientists","tag-soft","tag-stars","tag-view","tag-xray"],"featured_image_urls":{"full":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf.jpg",960,640,false],"thumbnail":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf-150x150.jpg",150,150,true],"medium":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf-300x200.jpg",300,200,true],"medium_large":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf-768x512.jpg",640,427,true],"large":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf.jpg",640,427,false],"1536x1536":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf.jpg",960,640,false],"2048x2048":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf.jpg",960,640,false],"covernews-featured":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf.jpg",960,640,false],"covernews-medium":["https:\/\/news678.top\/wp-content\/uploads\/2026\/08\/soft-x-ray-flash-supernova-sn-2026gzf-540x340.jpg",540,340,true]},"author_info":{"display_name":"admin","author_link":"https:\/\/news678.top\/?author=1"},"category_info":"<a href=\"https:\/\/news678.top\/?cat=8\" rel=\"category\">Tech<\/a>","tag_info":"Tech","comment_count":"0","_links":{"self":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts\/19346","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=19346"}],"version-history":[{"count":0,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts\/19346\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/media\/19347"}],"wp:attachment":[{"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=19346"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=19346"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=19346"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
