大家都读过盲人摸象的故事吧?其实,天文学里也有一个盲人摸象的故事!天文版盲人摸象要摸的是著名的面纱星云。面纱星云分散在十分广大的区域内却又非常暗淡,也由于以前的观测仪器不够给力,以至于那时的天文学家只能窥视它的部分区域,而不能一睹它的全貌。这样一来,对面纱星云的认识过程就有些像盲人摸象啦!天文学家“摸”出了面纱星云边缘一些很亮的部分,就想当然地认为是完整独立的星云,还给出了编号。下面带有英文字母的5张星云照片,正是从完整的面纱星云中“摸”出来的。现在要考考你的眼力了:你能分辨出它们原本位于面纱星云的哪个位置吗?
In fact, there is also a story of astronomical blind touch! Astronomical version of the blind touch as if to touch the famous veil of the veil. The veil of nephew dispersed in a very large area but very dim, but also because of the previous observational instrument is not enough to that time astronomers can only peep part of it, but can not see its picture. As a result, the understanding of veil nebula is somewhat like a blind person! Astronomer “touch ” out of the veil some bright edges of the nebula, of course, is considered to be a complete independent nebula, but also given the number. The following five photos with English letters, it is from the complete veil nebula “touch ” out. Now test your eyesight: Can you tell where they were originally in the veil of the veil?
