In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavour was risky – what, if anything, was going to show up? But what came back was nothing short of spectacular: an image of over 1,500 galaxies glimmering in a tiny sliver of the universe. Alex Hofeldt helps us understand the scale of this image.

1995年，科学家们将哈勃望远镜对准了北斗七星附近的一个天空区域。这个位置显然是空的，而且整个努力是有风险的--如果有什么东西会出现的话，会是什么呢？但是得到的结果却是无比的壮观：在宇宙的一小片区域内，有超过1500个星系的图像在闪烁。亚历克斯-霍菲尔特帮助我们理解这幅图像的规模。
