[center]The Tarantula Nebula
Credit & Copyright: Brad Moore
Explanation: First cataloged as a star, 30 Doradus is actually an immense star forming region in nearby galaxy The Large Magellanic Cloud. The region's spidery appearance is responsible for its popular name, the Tarantula Nebula, except that this tarantula is about 1,000 light-years across, and 180,000 light-years away in the southern constellation Dorado. If the Tarantual Nebula were at the distance of the Orion Nebula (1,500 light-years), the nearest stellar nursery to Earth, it would appear to cover about 30 degrees on the sky or 60 full moons. The spindly arms of the Tarantula Nebula surround NGC 2070, a cluster that contains some of the intrinsically brightest, most massive stars known. Intriguing details of the nebula's core can be seen in this remarkable skyscape, a composite of 31 hours of exposure time. This cosmic Tarantula also lies near the site of the closest recent supernova.

[center]蜘蛛星云
影像提供:Brad Moore[/center]
说明:作为第一颗被编类的恒星-剑鱼座30 (Doradus),它实际上是大麦哲伦星云附近一个巨大的恒星形成区域。蜘蛛星云区域中像蜘蛛一样的形状是它名字形成的原因,只可惜蜘蛛跨度只有1,000光年,距离南方的剑鱼座有180,000光年。如果蜘蛛星云远离距地球最近的恒星诞生区猎户座(1,500光年),它将在天空中覆盖30度或60个满月。蜘蛛星云细长的臂状物环绕着NGC2070,在这个星团中包含着一些目前所知固有的最亮,质量最大恒星。在这个显著的天空画面中可以看到星核的迷人景色,这幅画面是由31个小时曝光后合成的。这个宇宙蜘蛛也位于距离最新超新星最近的位置附近。
