Il s\u2019agit de la plus grande n\u00e9buleuse connue (dimension de l\u2019ordre de 1480 al.) et se trouve \u00eatre une importante p\u00e9pini\u00e8re de nouvelles \u00e9toiles. Sa magnitude est de 8.0, mais de 5.0 dans la bande du bleu (donc visible \u00e0 l\u2019\u0153il nu). En 2022 le t\u00e9lescope spatial Webb a permis d\u2019observer pr\u00e8s de 10000 jeunes \u00e9toiles, par infrarouge, qui jusqu\u2019alors \u00e9taient masqu\u00e9es par des poussi\u00e8res en lumi\u00e8re visible.<\/p>\n\n\n
