蜘蛛星云又名NGC2070,是大麦哲伦星云中一个巨大的恒星诞生区。蜘蛛星云因其蜘蛛般的外形而得名,这只“大蜘蛛”坐落于剑鱼座内,横跨约1 000光年,离地球约有165 000光年。尽管距离地球甚远,但它看上去与距地球约1 500光年的“猎户星云”一样明亮,这是因为它的面积约是猎户星云的50倍。蜘蛛星云的中心是一个直径约35光年的巨大蓝巨星簇R136.蜘蛛星云的大部分光芒都是R136散发的。而R136中又存在着迄今为止已知的最大恒星R136al。这颗恒星质量约为太阳的320倍,因其剧烈燃烧.产生的亮度约为太阳的1000万倍01987年2月,位于蜘蛛星云外围的蓝超巨星
Spider Nebula, also known as NGC 2070, is a huge star birthplace in the Great Magellanic Cloud. The spider’s nebula is named for its spider-like shape. The Spider’s Crane is located in the swordfish cradle, spanning about 1 000 light-years, about 165,000 light-years from Earth. Although it is a long way from Earth, it looks as bright as the “Orion Nebula” about 1,500 light-years from Earth because it is about 50 times larger than the Orion Nebula. The center of the Spider’s Nebula is a cluster of giant blue giant R136, about 35 light-years in diameter. Most of the rays of the Spider’s Nebula are emitted by the R136. In R136 there is again the largest known star R136al so far. The star is about 320 times the mass of the sun because of its violent burning, which produces about 10 million times the brightness of the sun. In February 1987, the blue supermassive star located outside the Spider’s Nebula
