Le 25 octobre 2025, nous nous retrouverons sur l’aire de la chapelle Notre Dame de l’Esp\u00e9rance \u00e0 Binic-\u00c9tables<\/a> pour une s\u00e9ance publique d’observation du ciel \u00e9toil\u00e9. La m\u00e9t\u00e9o le permettant, cette animation commencera au coucher du Soleil vers de 19h00 et se terminera aux alentours de 23h00.<\/p>\n\n\n\n

Ce sera l’occasion tout d’abord d’observer le premier croissant de Lune et le ph\u00e9nom\u00e8ne de lumi\u00e8re cendr\u00e9e dont nous donnerons l’explication. Viendra ensuite la com\u00e8te \u00ab Lemmon \u00bb<\/a> qui passe actuellement \u00e0 proximit\u00e9 de la Terre et du Soleil (un peu plus de 90 millions de km quand m\u00eame) pour un spectacle rare et difficilement pr\u00e9visible et que l’on peut voir en ce moment \u00e0 l\u2019\u0153il nu.<\/p>\n\n\n\n

Puis ce sera le tour de Saturne avec une lunette ou un t\u00e9lescope plus puissant, sixi\u00e8me plan\u00e8te du syst\u00e8me solaire, particuli\u00e8rement bien plac\u00e9e en ce moment, c\u00e9l\u00e8bre pour ses magnifiques anneaux et ses tr\u00e8s nombreux satellites dont Titan, le plus massif, devrait \u00eatre visible.<\/p>\n\n\n\n

L’obscurit\u00e9 progressant, ce sera le tour d’admirer les plus belles \u00e9toiles \u00ab fixes \u00bb, les constellations les plus facilement rep\u00e9rables et peut-\u00eatre la voie lact\u00e9e en fonction de la luminosit\u00e9 du ciel et de l’absence de pollution lumineuse.<\/p>\n\n\n\n

Il devrait \u00e9galement \u00eatre possible de voir quelques amas globulaires dont l’amas d’Hercule M13<\/a> est le plus beau repr\u00e9sentant dans l’h\u00e9misph\u00e8re nord. Quelques amas ouverts, tel que le double amas de Pers\u00e9e<\/a> et les Pl\u00e9iades<\/a> seront \u00e9galement visibles.<\/p>\n\n\n\n

Enfin, il devrait \u00eatre possible d’apercevoir la galaxie la plus proche de la n\u00f4tre, la galaxie d’Androm\u00e8de<\/a> encore appel\u00e9e M31 dans le catalogue de Charles Messier (astronome fran\u00e7ais du 18\u00e8me si\u00e8cle qui fut le premier \u00e0 r\u00e9pertorier les amas et n\u00e9buleuses) et qui est l’objet du ciel le plus lointain observable \u00e0 l\u2019\u0153il nu.<\/p>\n\n\n\n

N’oubliez pas de vous habiller chaudement avec une tenue adapt\u00e9e pour une nuit qui peut \u00eatre fraiche et humide.<\/p>\n\n\n\n

En cas de mauvais temps cette animation sera malheureusement annul\u00e9e.<\/p>\n\n\n\n
