估计楼主不准备翻译了。我就献丑吧。

Located inside the Large Magellanic Cloud (LMC) – one of our closest galaxies – in what some describe as a frightening sight, the Tarantula nebula is worth looking at in detail. Also known as 30 Doradus or NGC2070, the nebula owes its name to the arrangement of its bright patches that somewhat resemble the legs of a tarantula. Taking the name of one of the biggest spiders on Earth is very fitting in view of the gigantic proportions of this celestial nebula - it measures nearly 1,000 light years across!
在离我们银河系最近的星系之一——大麦哲伦星系(以下以简称LMC表示)里,蜘蛛星云虽然有一个令人恐惧的名字,却很值得详细的研究。蜘蛛星云又名NGC 2070或剑鱼座30,由于它的星云的亮块部分组成像蜘蛛的腿形状而被称为蜘蛛星云(在早期望远镜不是很高级时看上去确实像蜘蛛,我以前看见的黑白图片就像,现在ACS图像实在看不出蜘蛛形了——译注)。获得地球上最大的爬虫之一称号非常适合这只天上的蜘蛛——它横跨约1000光年的范围!
Its proximity, the favourable inclination of theLMC, and the absence of intervening dust make this nebula one of the best laboratories to better understand the formation of massive stars.This spectacular nebula is energised by an exceptionally high concentration of massive stars, often referred to as super star clusters.
蜘蛛星云离地球相对较近,而且它与地球之间没有多少尘埃阻隔,这使它成为LMC中相当有利于观测的天体,是一个更好了解大质量恒星演化史的最佳实验室。这个壮观的星云由内部一群高度密集的大质量恒星照亮,这些恒星群一般归类于超级星团(话说我只知道球状星团和疏散星团,这个算什么星团?——译注)
