M 78 – N\u00e9buleuse de Casper le Fant\u00f4me
\nSitu\u00e9e dans la constellation d’Orion, au-dessus des \u00e9toiles de la ceinture, M78 (ou NGC 2068) est une n\u00e9buleuse par r\u00e9flexion, c-\u00e0-d un nuage de poussi\u00e8re interstellaire qui brille par r\u00e9flexion de la lumi\u00e8re des brillantes \u00e9toiles bleues, qui \u00e9mettent un rayonnement ultraviolet. Parmi elles la plus brillante, HD 38563A, suivie de peu par HD 290862, toutes les deux de magnitude visuelle apparente +10.
\nUne \u00e9paisse bande de poussi\u00e8re s\u2019\u00e9tend en travers de l\u2019image obscurcissant la lumi\u00e8re des \u00e9toiles d\u2019arri\u00e8re-plan.
\nDistante de nous d’environ 1 600 ann\u00e9es-lumi\u00e8re, M78 aurait une extension de presque 4 ann\u00e9es-lumi\u00e8re.
