Une bonne opportunit\u00e9 pour sortir dehors et lever les yeux au ciel.[\/vc_column_text][vc_column_text]<\/p>\n

Quelles plan\u00e8tes au rendez-vous en mai ?<\/h2>\n

Tout au long de ce mois, Mars<\/strong> la plan\u00e8te rouge et V\u00e9nus<\/strong> la plan\u00e8te la plus brillante du ciel et celle surnomm\u00e9e \u00ab\u00a0l’\u00e9toile du Berger\u00a0\u00bb<\/strong> seront visibles en soir\u00e9e, juste apr\u00e8s le coucher du Soleil face \u00e0 l’Ouest. Les g\u00e9antes gazeuses Jupiter<\/strong> et Saturne<\/strong> seront aussi de la partie mais dans le ciel du matin, face \u00e0 l’Est, juste avant le lever du Soleil.[\/vc_column_text][vc_column_text]<\/p>\n

Quelles constellations observer en mai ?<\/h2>\n

Les constellations du printemps nous accompagneront en soir\u00e9e, face au Sud, avec par exemple le Bouvier<\/strong> et son \u00e9toile principale Arcturus, le Lion<\/strong> et son \u00e9toile principale Denebola et enfin la Vierge<\/strong> et son \u00e9toile Spica situ\u00e9e \u00e0 environ 250 ann\u00e9es-lumi\u00e8re de la Terre.<\/p>\n

Si vous \u00eates couche-tard ou l\u00e8ve-t\u00f4t, en d\u00e9but de nuit face \u00e0 l’Est, les constellations du ciel d’\u00e9t\u00e9 commenceront \u00e0 se lever. L’occasion de rep\u00e9rer le fameux \u00ab\u00a0triangle d’\u00e9t\u00e9\u00a0\u00bb<\/strong>\u00a0compos\u00e9 de l’\u00e9toile Vega de la constellation de la Lyre<\/strong>, l’\u00e9toile Alta\u00efr de la constellation de l’Aigle<\/strong> et enfin l’\u00e9toile Deneb de la constellation du Cygne<\/strong>.[\/vc_column_text][vc_column_text]<\/p>\n

Pluie d’\u00e9toiles filantes et \u00e9clipse de Lune<\/h2>\n

L’observation du ciel ne s’arr\u00eatera pas l\u00e0. Le 5 mai<\/strong>, la Terre traversera un nuage de poussi\u00e8re laiss\u00e9 par le passage de la c\u00e9l\u00e8bre com\u00e8te de Halley. Une pluie d’\u00e9toiles filantes pourra alors \u00eatre visible en seconde partie de nuit dans la direction de la constellation du Verseau<\/strong>. Bien que ce ne soit pas la pluie d’\u00e9toiles filantes la plus importante de l’ann\u00e9e (environ une dizaine de m\u00e9t\u00e9ores par heure) elle m\u00e9ritera toutefois d’\u00eatre observ\u00e9e loin de la pollution lumineuse des villes. Cette ann\u00e9e, la Lune sera presque pleine ce qui pourra emp\u00eacher une observation optimale.<\/p>\n

En parlant de Lune, ce m\u00eame jour<\/strong>, une \u00e9clipse<\/a> de Lune par la p\u00e9nombre pourra \u00eatre observ\u00e9e pour une grande partie de l’Europe de l’Est. Cette derni\u00e8re d\u00e9butera \u00e0 17h14 (heure de Paris). Chez nous en France, ce n’est que la fin du ph\u00e9nom\u00e8ne qui pourra \u00eatre observ\u00e9 aux alentours des 21h15<\/strong>. Cependant, les \u00e9clipses de Lune par la p\u00e9nombre ne sont pas tr\u00e8s spectaculaires. \u00c0 ce moment, la luminosit\u00e9 de notre satellite est l\u00e9g\u00e8rement moins lumineuse que la normale. Comme les lueurs du jour seront encore pr\u00e9sentes dans le ciel, le spectacle ne sera pas exceptionnel et pratiquement invisible.[\/vc_column_text][vc_column_text]<\/p>\n

Des rencontres c\u00e9lestes<\/h2>\n

De belles rencontres c\u00e9lestes appel\u00e9es conjonctions<\/em> seront aussi \u00e0 observer. La premi\u00e8re se d\u00e9roulera le 13 mai<\/strong> dans les lueurs du jour, o\u00f9 un croissant de Lune<\/strong> viendra rendre visite \u00e0 la plan\u00e8te aux anneaux Saturne<\/strong>, suivi du 17 mai<\/strong> d’un ballet c\u00e9leste entre la plus grosse plan\u00e8te du Syst\u00e8me Solaire Jupiter<\/strong> et notre satellite naturel. L’astre S\u00e9l\u00e8ne<\/strong> sera joueur et viendra m\u00eame occulter la plan\u00e8te, mais le ph\u00e9nom\u00e8ne se d\u00e9roulera en pleine apr\u00e8s-midi en France et ne sera donc pas visible. Les deux derni\u00e8res conjonctions du mois auront lieu le 23 mai<\/strong>, avec la Lune<\/strong> et la d\u00e9esse de l’amour V\u00e9nus<\/strong>, suivi le lendemain de la plan\u00e8te rouge, Mars<\/strong>.[\/vc_column_text][\/vc_column][vc_column width=\u00a0\u00bb1\/12″][\/vc_column][\/vc_row][vc_row][vc_column][vc_text_separator title=\u00a0\u00bbExp\u00e9rimentez \u00e0 Vulcania\u00a0\u00bb color=\u00a0\u00bbcustom\u00a0\u00bb style=\u00a0\u00bbdashed\u00a0\u00bb accent_color=\u00a0\u00bb#888888″][vc_row_inner][vc_column_inner width=\u00a0\u00bb1\/12″][\/vc_column_inner][vc_column_inner width=\u00a0\u00bb5\/12″][vc_single_image image=\u00a0\u00bb1285″ img_size=\u00a0\u00bbmedium\u00a0\u00bb onclick=\u00a0\u00bbcustom_link\u00a0\u00bb link=\u00a0\u00bbhttps:\/\/www.vulcania.com\/planetarium\/\u00a0\u00bb][\/vc_column_inner][vc_column_inner width=\u00a0\u00bb5\/12″][vc_column_text]<\/p>\n
