PuWe1 est une n\u00e9buleuse plan\u00e9taire assez grande, mais tr\u00e8s tr\u00e8s faible, dans la constellation du lynx. La n\u00e9buleuse a \u00e9t\u00e9 d\u00e9couverte en 1980 (article de d\u00e9couverte original : 1980A&A….87L…5P (harvard.edu)<\/a>) par Purgathofer et Weinberger sur les impressions du Palomar Deep Sky Survey. La n\u00e9buleuse est l’une des plus grandes n\u00e9buleuses plan\u00e9taires visibles dans notre ciel, avec un diam\u00e8tre de 20′ (presque \u00e9gal \u00e0 la pleine lune !). PuWe 1 est \u00e9galement l’un des plan\u00e9taires connus les plus proches avec une distance d’environ 1200 ann\u00e9es-lumi\u00e8re seulement. Il brille tr\u00e8s faiblement dans les longueurs d’onde H-alpha et OIII. Dans H-a, il a une luminosit\u00e9 de surface estim\u00e9e \u00e0 seulement 23,7 mag\/arcsec2 et dans OIII \u00e0 seulement 26,3 mag\/arcsec2. Les magnitudes int\u00e9gr\u00e9es sont respectivement de 8,6 et 11,2. Cela signifie que vous pouvez imaginer la n\u00e9buleuse comme une \u00e9toile de mag. 8.6 qui est d\u00e9focalis\u00e9 \u00e0 la taille de la lune. Cela donne une indication de l’incroyable faiblesse de la n\u00e9buleuse. La n\u00e9buleuse a un diam\u00e8tre estim\u00e9 \u00e0 environ 4 al, et est donc probablement un reste tr\u00e8s ancien d’une n\u00e9buleuse plan\u00e9taire qui s’est \u00e9tendue si loin que les gaz restants ne sont que faiblement \u00e9nergis\u00e9s par l’\u00e9toile centrale.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":9604,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"image","meta":{"footnotes":""},"categories":[102,122,126,152,367,504,541],"tags":[553],"class_list":["post-9609","post","type-post","status-publish","format-image","has-post-thumbnail","hentry","category-nebuleuse","category-haoiii-rvb","category-observatoire-dorange","category-toutes-categories","category-telescope-newton-16-skyvision","category-favorites","category-saison-2022","tag-puwe1","post_format-post-format-image"],"_links":{"self":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts\/9609","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=9609"}],"version-history":[{"count":7,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts\/9609\/revisions"}],"predecessor-version":[{"id":9622,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts\/9609\/revisions\/9622"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/media\/9604"}],"wp:attachment":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=9609"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=9609"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=9609"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
