Vers la fin du XVIIIe<\/sup> si\u00e8cle, l’astronome fran\u00e7ais Charles Messier \u00e9tablit un catalogue qui contiendra \u00e0 la fin 110 \u00ab n\u00e9buleuses \u00bb, comme on appelait alors indistinctement les objets diffus observ\u00e9s dans le ciel. Il est d’ailleurs amusant de rappeler que Messier n’\u00e9tait pas particuli\u00e8rement int\u00e9ress\u00e9 par ces n\u00e9buleuses; en fait il \u00e9tait passionn\u00e9 par les com\u00e8tes et son \u00e9tude approfondie du ciel lui avait fait d\u00e9couvrir des n\u00e9buleuses qu’il n’a catalogu\u00e9es que pour les \u00e9carter de ses recherches com\u00e9taires ! Il est assez savoureux de constater qu’il n’est devenu mondialement connu que gr\u00e2ce \u00e0 son catalogue et non pas pour les quelques 20 \u00e0 25 com\u00e8tes qu’il a pu d\u00e9couvrir au cours de sa vie …
\n<\/span><\/p>\n

Il s’est av\u00e9r\u00e9 plus tard que ces \u00ab\u00a0n\u00e9buleuses\u00a0\u00bb \u00e9taient des objets tr\u00e8s divers, qu’on peut ranger aujourd’hui dans 4 grandes cat\u00e9gories : des amas globulaires<\/strong>, des amas ouverts<\/strong>, des galaxies<\/strong> et plusieurs types de n\u00e9buleuses<\/strong> proprement dites.<\/span><\/p>\n

Les astronomes amateurs utilisent encore tr\u00e8s r\u00e9guli\u00e8rement ce catalogue qui recense 110 objets parmi les plus beaux du \u00ab\u00a0ciel profond\u00a0\u00bb, objets visibles dans le ciel de l’h\u00e9misph\u00e8re bor\u00e9al (nord).<\/span><\/p>\n

Depuis, on a rassembl\u00e9 des nombres consid\u00e9rables d’objets c\u00e9lestes dans d’autres catalogues comme NGC<\/strong> (New General Catalogue) qui contient 7.840 objets du ciel profond. Il existe de tr\u00e8s nombreux autres catalogues, parfois sp\u00e9cialis\u00e9s dans des types d’objets particuliers.<\/span><\/p>\n

Les plus difficiles \u00e0 rep\u00e9rer sont la galaxie M110, \u00e0 c\u00f4t\u00e9 de la grande galaxie d’Androm\u00e8de (M31) et la galaxie du Triangle, M33. Les deux heures suivantes servent \u00e0 observer la vingtaine d\u2019objets dispers\u00e9s de la Poupe \u00e0 Cassiop\u00e9e, admirer une cinquantaine d\u2019objets, essentiellement des galaxies. <\/span>La phase finale consiste \u00e0 observer des dizaines d’amas ouverts et globulaires et des n\u00e9buleuses.<\/span><\/p>\n
