La n\u00e9buleuse du Cocon se trouve \u00e0 4000 ann\u00e9es-lumi\u00e8re. La couleur rouge est \u00e9mise par l\u2019hydrog\u00e8ne mol\u00e9culaire excit\u00e9 par le rayonnement des jeunes \u00e9toiles bleues. Le bleu vient de la lumi\u00e8re de ces jeunes \u00e9toiles qui se r\u00e9fl\u00e9chit sur des nuages de poussi\u00e8res. L\u2019\u00e9toile brillante au centre de la n\u00e9buleuse creuse une cavit\u00e9 dans le gaz et la poussi\u00e8re du nuage mol\u00e9culaire.<\/p>\n

Rmq: Il faudrait de plus longs temps de pose pour diminuer le bruit de fond et faire ressortir le bleu.<\/p>\n\n\n
