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 108 200 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.
This image is too large to be easily displayed at full resolution and is best appreciated using the zoom tool. Read about the composition of this 9 gigapixel image in this newsletter.
这是在智利ESO帕拉纳尔天文台的Vista望远镜上拍摄到的银河系中心部分的引人注目的景象。这张巨大的图片是108,200乘81,500像素,包含近90亿像素。它是通过将来自Vista的数千张不同的图像,通过三个不同的红外滤镜,组合成一个巨大的马赛克。这些数据构成了VVV公众调查的一部分,并被用来研究银河系中部比以往任何时候都多的单个恒星。因为Vista有一个对红外光敏感的照相机,它可以透过阻挡光学望远镜视野的大部分灰尘来观察,尽管更多的不透明尘埃细丝在这张照片中仍然显示得很好。这幅图像太大了,很难在完全分辨率下显示,最好用缩放工具来欣赏。在这份通讯中阅读这张90亿像素图像的组成。
