Cette photographie illustre toute la violence des phases finales de la naissance d\u2019une \u00e9toile, au cours desquelles un jeune objet c\u00e9leste peut affecter durablement son environnement proche.<\/p>\n<\/div>\n<p>Cette jeune \u00e9toile, nomm\u00e9e S106 IR, brille intens\u00e9ment au c\u0153ur d\u2019un nuage d\u2019hydrog\u00e8ne et \u00e9jecte de la mati\u00e8re \u00e0 haute vitesse dans un maelstr\u00f6m de gaz et de poussi\u00e8re. L\u2019\u00e9toile S106 IR, d\u2019environ 15 fois la masse du Soleil, est entr\u00e9e en phase finale de stellog\u00e9n\u00e8se. L\u2019\u00e9toile est au seuil de son \u00e2ge adulte, sa s\u00e9quence principale qui correspondra \u00e0 une longue p\u00e9riode de stabilit\u00e9.<\/p>\n<p>Pour l\u2019instant, S106 IR figure encore dans son nuage parental, mais elle se rebelle violemment contre lui. Les mati\u00e8res expuls\u00e9es par la jeune \u00e9toile ont donn\u00e9 au grand nuage de gaz une forme de sablier et ont rendu son hydrog\u00e8ne extr\u00eamement chaud et instable. La structure complexe de cet objet c\u00e9leste se dessine clairement sur cette image acquise par Hubble.<\/p>\n<p>La jeune \u00e9toile affecte \u00e9galement les r\u00e9gions gazeuses environnantes, dont la temp\u00e9rature atteint les 10 000 degr\u00e9s Celsius ! Les zones bleut\u00e9es de l\u2019image sont celles o\u00f9 la radiation stellaire fait briller le plus intens\u00e9ment le nuage d\u2019hydrog\u00e8ne.<\/p>\n<p>Ces deux zones sont s\u00e9par\u00e9es par une r\u00e9gion rouge\u00e2tre riche en poussi\u00e8res. Cette zone beaucoup plus sombre cache partiellement S106 IR, dont on peut cependant distinguer la lumi\u00e8re rayonner depuis la partie centrale de la couche de poussi\u00e8re.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Hubble space telescope has captured this amazing image of a giant gas cloud lit up by a bright young star.
