On s’en doutait un peu : le cru 2014 de l’essaim d’\u00e9toiles filantes<\/a> des Pers\u00e9ides ne restera pas dans les m\u00e9moires. La pr\u00e9sence de la Lune (avec une Super Lune<\/a> le 10 ao\u00fbt) n’aura gu\u00e8re permis de profiter des poussi\u00e8res abandonn\u00e9es par la com\u00e8te Swift-Tuttle qui viennent se consumer dans l’atmosph\u00e8re terrestre entre le 17 juillet et le 24 ao\u00fbt (avec un maximum autour du 12 ao\u00fbt).<\/p>\n

Si on ajoute des conditions m\u00e9t\u00e9orologiques souvent d\u00e9sastreuses, on imagine ais\u00e9ment que les nuits d\u00e9gag\u00e9es \u00a0et sans \u00e9clairage lunaire n’ont pas \u00e9t\u00e9 tr\u00e8s nombreuses.<\/p>\n

Les amateurs d’\u00e9toiles filantes devront patienter jusqu’au mois de d\u00e9cembre pour profiter d’un autre essaim tr\u00e8s actif : celui des G\u00e9minides du 7 au 17, le maximum le 14 d\u00e9cembre tombant avec le Dernier Quartier de Lune<\/a>. D’excellentes conditions, donc, si la m\u00e9t\u00e9o le veut bien !<\/p>\n

Outre le radiant (d’o\u00f9 semblent s’\u00e9chapper les \u00e9toiles filantes) on peut \u00e9galement voir la galaxie d’Androm\u00e8de (Messier 31) et l’amas d’\u00e9toiles des Pl\u00e9iades<\/a> (Messier 45).<\/p>\n","protected":false},"excerpt":{"rendered":"
