Whether it&#8217;s investigating the financials of Elon Musk&#8217;s pro-Trump PAC or producing our latest documentary, &#8216;The A Word&#8217;, which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.<\/p>\n<p class=\"sc-1uza6dc-0 iCTyfe\">At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.<\/p>\n<p class=\"sc-1uza6dc-0 iCTyfe\">The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls.

They have perplexed scientists for a decade, despite scientists having spotted more than a dozen of them.<\/p>\n<p>Possible explanations have included everything from strange supernovae to interstellar gas being eaten by a <a href=\"https:\/\/www.independent.co.uk\/topic\/black-hole\" target=\"_blank\" rel=\"noopener\">black hole<\/a>. But now scientists believe they have another explanation.<\/p>\n<p>That came after researchers looked at a new example, found last year and the brightest of its kind.<\/p>\n<p>That new example suggests that the LFBOTs are caused by \u201cextreme tidal disruption\u201d. That happens when vast black holes eats its companion star, tearing it to shreds.<\/p>\n<p>As well as helping explain the mysterious phenomenon, the research could help us better understand how black holes work and the ways that stars evolve, according to the researchers behind it. For instance, huge black holes have been seen in experiments, but scientists still don\u2019t know how they actually come to form.<\/p>\n<p>\u201cTheorists have come up with many ways to explain how we get these large black holes, to explain what LIGO sees,\u201d said Raffaella Margutti, UC Berkeley associate professor of astronomy and physics, in a statement. \u201cLFBOTs allow you to get at this question from a completely different angle.<\/p>\n<p>\u201cThey also allow us to characterize the precise location where these things are inside their host galaxy, which adds more context in trying to understand how we end up with this setup \u2014 a very large <a href=\"https:\/\/www.independent.co.uk\/topic\/black-hole\" target=\"_blank\" rel=\"noopener\">black hole<\/a> and a companion.\u201d<\/p>\n<p>The new work is described in two new papers \u2013\u00a0\u2018The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the X-rays and Radio\u2019 and \u2018The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the Ultraviolet to the Near-Infrared\u2019 \u2013\u00a0that are available online and have been accepted for publication in The Astrophysical Journal Letters.<\/p>\n","protected":false},"excerpt":{"rendered":"Your support helps us to tell the story From reproductive rights to climate change to Big Tech, The&hellip;\n","protected":false},"author":2,"featured_media":640081,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3844],"tags":[70,413,16,15],"class_list":{"0":"post-640080","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-uk","11":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115740208283927920","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/640080","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=640080"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/640080\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/640081"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=640080"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=640080"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=640080"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
