L\u2019article d\u2019aujourd\u2019hui pr\u00e9sente bri\u00e8vement le ph\u00e9nom\u00e8ne d\u2019\u00e9clipse lunaire.<\/p>\n\n\n\n

Tout d\u2019abord, qu\u2019est-ce qu\u2019une \u00e9clipse lunaire ?<\/p>\n\n\n\n

C\u2019est un ph\u00e9nom\u00e8ne qui a lieu lorsque la Terre est plac\u00e9e \u00ab pile \u00bb entre la Lune et le Soleil.<\/p>\n\n\n\n

Repr\u00e9sentation sch\u00e9matique d’une \u00e9clipse de Lune. (Sch\u00e9ma Eggishorn, traduction Lib\u00e9ration)<\/em><\/p>\n\n\n\n

Mais pourquoi cet \u00e9v\u00e9nement est-il si int\u00e9ressant ?<\/p>\n\n\n\n

Cet \u00e9v\u00e9nement pr\u00e9sente une caract\u00e9ristique tr\u00e8s sp\u00e9ciale, la couleur de la Lune. Vous allez s\u00fbrement vous dire que \u00ab la Lune doit \u00eatre noire car elle ne re\u00e7oit plus la lumi\u00e8re du Soleil \u00bb. Et bien non, elle sera, dans le cas de celle observ\u00e9e, de couleur rouge et cela s\u2019explique par les ph\u00e9nom\u00e8nes de r\u00e9fraction, d\u2019absorption et d\u2019\u00e9mission. Des ph\u00e9nom\u00e8nes naturels qui affectent toute lumi\u00e8re changeant de milieu.<\/p>\n\n\n\n

Dans le cas de l\u2019\u00e9clipse lunaire que nous avons observ\u00e9e, la raie lumineuse qui a percut\u00e9 la Lune \u00e9tait de couleur rouge, lui donnant sa couleur \u00e9carlate.<\/p>\n\n\n\n
