欧洲南方天文台发布最新银河高清图片

This striking view of the central parts of the Milky Way was obtained with the VISTA survey telescope at ESO’s Paranal Observatory in Chile. This huge picture is 108 500 by 81 500 pixels and contains nearly nine billion pixels. It was created by combining thousands of individual images from VISTA, taken through three different infrared filters, into a single monumental mosaic. These data form part of the VVV public survey and have been used to study a much larger number of individual stars in the central parts of the Milky Way than ever before. Because VISTA has a camera sensitive to infrared light it can see through much of the dust blocking the view for optical telescopes, although many more opaque dust filaments still show up well in this picture.

2012年10月24日消息（具体拍摄时间不明），欧洲南方天文台提供的图像显示出银河系中心区域的景象，由VISTA巡天望远镜在智利的帕拉纳尔天文台观测。这幅巨大的高清图片原图有90亿像素。由VISTA的数千幅图像制成，通过三种不同的红外滤光器，到一个单一的巨大马赛克之中。这些数据涵盖了称为银河膨胀区的地区，已被用于对银河中心的更大数量的单个恒星的研究。由于VISTA有一个相机对红外光敏感，所以它可以穿透大部分挡住视线的尘埃，尽管如此，图像中仍然出现一些不透明的尘埃。
