Une com\u00e8te italienne :<\/h5>\n

Apr\u00e8s l’incendie qui a ravag\u00e9 une partie de Notre-Dame de Paris le 15 avril, chacun cherche des souvenirs de cette illustre cath\u00e9drale qui a subi le m\u00eame sort que celle de Reims<\/a> en septembre 1914. Pour les astronomes, c’est avec la com\u00e8te Donati (C\/1858 L1) qu’on retrouve le prestigieux \u00e9difice.<\/p>\n

La com\u00e8te Donati au-dessus de Notre-Dame de Paris le 4 octobre 1858. Dessin r\u00e9alis\u00e9 par E. Guillemin et Ph. Benoist<\/figcaption><\/figure>\n

La com\u00e8te fut d\u00e9couverte le 2 juin 1858 par Giovanni Battista Donati. Cet astronome italien travaillait alors \u00e0 l’Observatoire de Florence, la ville o\u00f9 observa avant lui Galil\u00e9e<\/a>.<\/p>\n

Un signe du ciel :<\/h5>\n

Les hommes ont toujours associ\u00e9 le passage des com\u00e8tes \u00e0 des \u00e9v\u00e9nements terrestres, et celle de Donati ne d\u00e9rogea pas \u00e0 cette r\u00e8gle. Dans son livre Comet Lore : Halley’s Comet in History and Astronomy<\/em> publi\u00e9 en 1910, Edwin Emerson \u00e9crivit \u00e0 propos de C\/1858 L1 : “Cette com\u00e8te, qui semblait foncer droit du z\u00e9nith et avait une queue incurv\u00e9e fut observ\u00e9e de juin 1858 \u00e0 avril 1859. Imm\u00e9diatement apr\u00e8s sa disparition, la guerre \u00e9clata en Italie entre les Fran\u00e7ais et les Italiens d’un c\u00f4t\u00e9 et les Autrichiens de l’autre, se terminant par la sanglante bataille de Solf\u00e9rino”<\/em>.<\/p>\n

Notre-Dame avait sa fl\u00e8che :<\/h5>\n

En France c’est en octobre 1858 qu’elle fut dessin\u00e9e au-dessus de Notre-Dame de Paris par E. Guillemin et Ph. Benoist. La gravure fut publi\u00e9e dans “Le ciel”, c\u00e9l\u00e8bre ouvrage de vulgarisation de l’\u00e9crivain scientifique fran\u00e7ais Am\u00e9d\u00e9e Guillemin publi\u00e9 6 ans plus tard.\u00a0\u00c0 cette \u00e9poque la pollution lumineuse<\/a> n’existait pas et le ciel \u00e9toil\u00e9 \u00e9tait accessible \u00e0 tous m\u00eame dans les plus grandes villes. Vincent Van Gogh profitera aussi de cette chance quand il peindra ses ciels \u00e9toil\u00e9s<\/a> 30 ans apr\u00e8s. En 1858 la cath\u00e9drale de Paris avait l’aspect que nous lui connaissions jusqu’\u00e0 hier : la fl\u00e8che imagin\u00e9e par l’architecte Eug\u00e8ne Viollet-le-Duc venait juste d’\u00eatre achev\u00e9e. Elle s’est effondr\u00e9e au cours de l’incendie du 15 avril 2019…<\/p>\n","protected":false},"excerpt":{"rendered":"
