This has now apparently reversed &#8230;&#8217;<\/p>\n<p>That assertion directly challenges earlier commentary that the interstellar visitor was essentially hidden from view as it passed behind the Sun.<\/p>\n<p>For example, one source reported that &#8216;3I\/ATLAS is behind the Sun from Earth &#8230; it can&#8217;t be seen in Earth&#8217;s sky&#8217; at present.

On the other hand, Brandenburg&#8217;s observation hints that the comet&#8217;s unusual jet activity or its plasma interactions may have rendered it bright enough to detect, at least through specialised instruments.<\/p>\n<p>If confirmed, this would indicate that 3I\/ATLAS is behaving in unexpected ways, perhaps shedding more dust and gas than anticipated, or even generating its own electromagnetic effects visible through space-based telescopes.<\/p>\n<p>Such behaviour would make it the first interstellar comet observed under near-solar conditions in real time, adding to its already extraordinary status as only the third confirmed object from beyond our Solar System.<\/p>\n<blockquote class=\"twitter-tweet\" data-conversation=\"none\">\n<p lang=\"en\" dir=\"ltr\">Dear Friends, The reports that 3I ATLAS , rather than being behind the Sun at Perihelion on Oct 29 ( that&#8217;s tomorrow) is actually Quite Visible in the sky away from the Sun are confirmed <a href=\"https:\/\/t.co\/BK2MZsUfOC\">https:\/\/t.co\/BK2MZsUfOC<\/a> .

Whether seen through the Sun&#8217;s haze or emerging freshly from it, 3I\/ATLAS continues to defy conventional expectations.<\/p>\n<p>Combined with Brandenburg&#8217;s provocative insight, its strange behavior ensures that this cosmic wanderer remains at the centre of one of astronomy&#8217;s most fascinating current debates.<\/p>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"A renowned plasma physicist has stunned the astronomical community by claiming that 3I\/ATLAS is visible, not obscured behind&hellip;\n","protected":false},"author":2,"featured_media":536263,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3845],"tags":[97046,168460,171276,52729,141821,168703,74,70,413,16,15],"class_list":{"0":"post-536262","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-physics","8":"tag-3i-atlas","9":"tag-3i-atlas-news","10":"tag-3i-atlas-update","11":"tag-interstellar","12":"tag-interstellar-comet","13":"tag-interstellar-comet-3i-atlas","14":"tag-physics","15":"tag-science","16":"tag-space","17":"tag-uk","18":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115459660564172170","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/536262","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=536262"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/536262\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/536263"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=536262"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=536262"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=536262"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
