In the Heart of the Tarantula Nebula

Explanation: In the heart of monstrousTarantula Nebula lies huge bubbles of energetic gas, long filaments of darkdust, and unusually massive stars. In the center of this heart, is a knot ofstars so dense that it was once thought to be a single star. This star cluster,labeled as R136 or NGC 2070, is visible just above the center of the featured image and home to a great number of hot young stars. The energetic light fromthese stars continually ionizes nebula gas, while t heir energetic particle windblows bubbles and defines intricate filaments. The representative colorpicture, a digital synthesis of images from the NASA/ESA orbiting Hubble SpaceTelescope and ESO\\\\'s groundbased New Technology Telescope, shows great detailsof the LMC nebula\\\\'s tumultuous center. The Tarantula Nebula, also known as the30 Doradus nebula, is one of the largest star formation regions known, and hasbeen creating unusually strong episodes of star formation every few millionyears.
蜘蛛星云的中心
在蜘蛛星云的中心分布着巨大的高能气泡，长长的黑暗尘埃纤维，以及质量格外大的恒星。在星云中心的中央是一个曾经被误认为单颗恒星的致密恒星聚集点。这个星团被编录为R136或者NGC2070，位于这张特写照片的中央上方，也是大量年轻炽热恒星的家园。恒星发出的高能星光持续不断地电离星云内的气体，同时高能粒子风还吹出气泡并勾勒出复杂的暗条纤维。这张颇具代表色的照片经过处理，结合哈勃太空望远镜和ESO的地面新技术望远镜拍摄到的数据，显示出大麦哲伦星云（LMC）喧闹中心的大量细节。蜘蛛星云还被称为剑鱼座30，是迄今为止已知的最大恒星形成区之一，每数百万年就会生成异常剧烈的恒星形成潮。
