SH2-180<\/b>\u00a0est un n\u00e9buleuse d’\u00e9mission visible dans la constellation de\u00a0Cassiopeia<\/a>.<\/p>\n

Il localise dans la partie nord-ouest de la constellation, \u00e0 environ 2 \u00b0 ENE \u00e9toile \u03ba Cassiopeiae; le meilleur moment pour votre observation dans le ciel du soir tombe entre les mois d’Ao\u00fbt et Janvier et est grandement facilit\u00e9e par des observatoires dans les r\u00e9gions ‘h\u00e9misph\u00e8re nord terrestre, o\u00f9 il pr\u00e9sente\u00a0circumpolaire<\/a>\u00a0jusqu’\u00e0 ce que les r\u00e9gions temp\u00e9r\u00e9es chaudes.<\/p>\n

\u00catre \u00e0 une distance d’environ 6 100\u00a0parsecs<\/a>\u00a0(A propos 19900 ann\u00e9es-lumi\u00e8re)[2]<\/a><\/sup>\u00a0Sh2-180 vient de se coucher sur bras Norma, au-del\u00e0 donc de grands complexes li\u00e9s \u00e0\u00a0associations OB<\/a>\u00a0visible dans Cassiop\u00e9e, qui tombent presque tout le monde dans le plus profond\u00a0bras de Pers\u00e9e<\/a>. On croit que la t\u00eate de l’ionisation de son gaz et LS I +62,139, une \u00e9toile bleue de s\u00e9quence principale avec classe spectrale O7.5V; Les estimations sur la distance \u00e0 cette \u00e9toile qui indique une valeur de 5150 \u00b1 1300 parsecs,[4]<\/a><\/sup>\u00a0que bien qu’il soit plus petit que l’estimation de 6100. parsecs, il est tr\u00e8s en contraste avec elle, compte tenu de la marge d’incertitude. Au-del\u00e0 de ces donn\u00e9es, la n\u00e9buleuse semble avoir \u00e9t\u00e9 peu \u00e9tudi\u00e9, et son filiforme, qui rappelle un\u00a0reste supernova<\/a>, Il soul\u00e8ve d’autres questions.<\/p>\n<\/div><\/div><\/div>
