Alcune nebulose sono caratterizzate dall’ospitare al loro interno fenomeni di\u00a0formazione stellare<\/a>, come le\u00a0nubi molecolari<\/a>, le\u00a0nebulose oscure<\/a>\u00a0e le\u00a0regione H II<\/a>; altre, come le\u00a0nebulose a riflessione<\/a>, brillano della luce emessa da una stella che transita al loro interno, come\u00a0NGC 1435<\/a>\u00a0che circonda la stella\u00a0Merope<\/a>\u00a0delle\u00a0Pleiadi<\/a>. Altre nebulose ancora si originano a seguito della morte di una stella, come le\u00a0nebulose planetarie<\/a>\u00a0o i\u00a0resti di supernova<\/a>. (wikipedia…<\/a>)<\/p>\n
