L‘Astronomie, en plus du ballet saisonnier des constellations et des plan\u00e8tes, nous offre de temps \u00e0 autre quelques spectacles impromptus : des com\u00e8tes , des ast\u00e9roides fr\u00f4leurs et cette ann\u00e9e une Supernova !<\/span><\/strong><\/p>\n

Chance suppl\u00e9mentaire, celle-ci est presque simple \u00e0 observer puisque situ\u00e9e, relativement proche dans le cosmos \u00e0 “seulement” 21 millions d’ann\u00e9es lumi\u00e8re. Certes pas assez lumineuse pour \u00eatre observ\u00e9e \u00e0 l’oeil nu, elle se trouve dans la grande Ourse\u00a0 plus pr\u00e9cis\u00e9ment dans la galaxie dite du “Tourniquet” , M101<\/p>\n

\u00a0Cette Supernova \u00e0 \u00e9t\u00e9 d\u00e9couverte le 19 mai<\/strong> derri\u00e8re un bon t\u00e9lescope de 2m et par un sp\u00e9cialiste des petits objets, M.

<\/em>Les Fadas du pixels (Alain, Jack et Cyril dans les champs )<\/em> ont d\u00e9cid\u00e9 de profiter de l’\u00e9v\u00e9nement pour faire quelques images de la grande galaxie. A gauche se trouve une belle image du champ autour de M101, prise par Cyril avec 500mm de focale. A cette distance on ne distingue encore rien de \u00a0SN 2023ixf, qui est le nom de code de la S<\/strong>uperN<\/strong>ova 2023 i<\/strong> (1\u00e8re quinzaine de mai ) XF<\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.17.6″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.17.6″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.17.6″ _module_preset=”default” text_font_size=”17px” text_letter_spacing=”1px” text_line_height=”1.7em” global_colors_info=”{}”]

Selon les dires des sp\u00e9cialistes, il s’agit de la Supernova la plus proche depuis plus de dix ans, ce qui en fera un objet d’\u00e9tude passionnant.<\/p>\n

Cette \u00e9toile modeste avait d\u00e9j\u00e0 \u00e9t\u00e9 observ\u00e9e par le satellite Spitzer<\/strong> et montrait quelques signes avant-coureur de son explosion.<\/p>\n

Autre coup de chance, mon t\u00e9lescope sortait de r\u00e9vision d\u00e9but avril. Apr\u00e8s avoir rong\u00e9 mon frein avant de le tester, ma premi\u00e8re cible fut justement M101.( ici la focale est de 1550 mm)<\/em><\/p>\n
