30 Doradus: The Tarantula Zone
Credit & Copyright: S. Points et al., NOAO, AURA, NSF
Explanation: The Tarantula Nebula is more than 1,000 light-years across - a giant emission nebula within our neighboring galaxy the Large Magellanic Cloud. Inside this cosmic arachnid lies a central young cluster of massivestars, cataloged as R136, whose intense radiation and strong winds have helped energize the nebular glow and shape the spidery filaments. In this impressive color mosaic of images from the Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile, other young star clusters can be seen still within the nebula's grasp. Also notable among the denizens of the Tarantula zone are several dark clouds, sprawling wispy filaments of gas, compact emission nebula, nearly spherical supernova remnants, and areas surrounding hot stars known as superbubbles. The rich mosaic's field of view covers an area on the sky about the size of the full moon in the southern constellation Dorado.

大麦哲伦星系的毒蜘蛛星云作者: 夜猫子 时间: 2005-12-12 22:41
壮观！作者: 夜空 时间: 2005-12-12 23:11 标题: 中文翻译 说明：蜘蛛星云是一个位于我们的邻居星系——大麦哲伦云中的巨大发射星云，其大小超过1000光年。在这个宇宙级蜘蛛的中心，有一个由大质量恒星组成的、编号为R136的年轻星团，它发出的强烈辐射和吹出的猛烈星风使得星云发光，并形成了蜘蛛腿状的细丝。这幅让人印象深刻的镶嵌彩色图像，是由智利 Cerro Tololo美洲天文台的Curtis施密特望远镜拍摄的，在图中可以看到星云中还有其它的年轻星团。蜘蛛星云地带的居民周围还有一些暗云、向外蔓延的一缕缕丝状气体、致密的发射星云、邻近的球形超新星遗迹，还有环绕着热星的著名的超级气泡区域，它们也同样引人注目。这张镶嵌图像丰富的视野涵盖南天剑鱼座天区的范围，约是满月的大小。（翻译：刘媛媛）
