New images from the NASA\/ESA Hubble Space Telescope and ESA\u2019s Euclid mission have revealed the complex, multi-shell structure of the extraordinary planetary nebula NGC 6543, also known as the Cat\u2019s Eye Nebula.<\/p>\n

The Cat\u2019s Eye Nebula<\/a> is located about 4,300 light-years away from Earth in the constellation of Draco.<\/p>\n

The object has captivated astronomers for decades with its elaborate and multilayered structure.<\/p>\n

\u201cPlanetary nebulae, so-called because of their round shape when viewed through early telescopes, are in fact expanding gas thrown off by stars in their final stages of evolution,\u201d Hubble and ESA astronomers said in a statement.<\/p>\n

\u201cIt was the Cat\u2019s Eye Nebula itself where this fact was first discovered in 1864, examining the spectrum of its light reveals the emission from individual molecules that\u2019s characteristic of a gas, distinguishing planetary nebulae from stars and galaxies.\u201d<\/p>\n

In the near-infrared and visible-light image from Euclid, the arcs and filaments of the nebula\u2019s bright central region are situated within a halo of colorful fragments of gas zooming away from the star.<\/p>\n

\u201cThis ring was ejected from the star at an earlier stage, before the main nebula at the center formed,\u201d the astronomers said.<\/p>\n

\u201cThe whole nebula stands out against a backdrop teeming with distant galaxies, demonstrating how local astrophysical beauty and the farthest reaches of the cosmos can be seen together in modern astronomical surveys.\u201d<\/p>\n

Within this broad view of the nebula and its surroundings, Hubble captured the very core of the billowing gas with high-resolution visible-light images.<\/p>\n

\u201cThe data reveal a tapestry of concentric shells, jets of high-speed gas and dense knots sculpted by shock interactions, features that appear almost surreal in their intricacy,\u201d the researchers said.<\/p>\n

\u201cThese structures are believed to record episodic mass loss from the dying star at the nebula\u2019s center, creating a kind of cosmic \u2018fossil record\u2019 of its final evolutionary stages.\u201d<\/p>\n

\u201cCombining the focused view of Hubble with Euclid\u2019s deep field observations not only highlights the nebula\u2019s exquisite structure but also places it within the broader context of the Universe that both space telescopes explore.\u201d<\/p>\n

\u201cTogether, these missions provide a rich and complementary view of NGC 6543 \u2014 revealing the delicate interplay between stellar end-of-life processes and the vast surrounding space.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"New images from the NASA\/ESA Hubble Space Telescope and ESA\u2019s Euclid mission have revealed the complex, multi-shell structure…\n","protected":false},"author":2,"featured_media":329710,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[152220,10805,152062,5621,61,60,91,13923,152221,70273,82],"class_list":{"0":"post-329709","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-cats-eye-nebula","9":"tag-esa","10":"tag-euclid","11":"tag-hubble","12":"tag-ie","13":"tag-ireland","14":"tag-nasa","15":"tag-nebula","16":"tag-ngc-6543","17":"tag-planetary-nebula","18":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/329709","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=329709"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/329709\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/329710"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=329709"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=329709"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=329709"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
