We are planning to use the new VISTA wide-field survey telescope in the Atacama desert of Chile, to make a near-infrared sky map. VISTA with its 4-metre mirror and 67-megapixel 3-tonne infrared camera will be the world's most powerful survey telescope when operational in 2008. Our map will cover two large stripes of the sky: each stripe will be approximately 75 degrees long and 10 degrees wide, and together they will cover 5 percent of the entire sky. Both stripes are directed away from the plane of our own Milky Way galaxy (one above and one below) to give a clear view of the distant universe. This area will be imaged in 5 different colours of near-infrared light, covering wavelengths between twice and 4 times that of ordinary visible light. The map will reveal objects up to 40 times fainter than existing infrared all-sky surveys. In addition, visible-light (near ultraviolet to red) images of the same area will be made by other wide-field telescopes, to give a combined survey with 9 colours. The resulting sky map will produce a catalogue of over 10 million galaxies and several million stars with this 9-colour information. Astronomers will use these for many purposes: for statistical analyses of the distribution of galaxies and stars, in particular to make a 3-dimensional map of the distribution of distant galaxies; to pinpoint objects detected by telescopes at other wavelengths; and to search for very rare objects such as the most distant quasars, which can be picked out since they will have peculiar colours unlike those of normal stars.

我们计划在智利阿塔卡马沙漠使用新的VISTA宽视场巡天望远镜，制作近红外天空图。VISTA拥有4米长的反射镜和6700万像素的3吨重的红外摄像机，将于2008年投入使用，成为世界上最强大的巡天望远镜。我们的地图将覆盖天空的两个大条纹：每个条纹大约75度长，10度宽，它们将覆盖整个天空的5%。两条条纹都指向远离我们银河系平面的方向（一条在上，一条在下），以清晰地看到遥远的宇宙。这一区域将用5种不同颜色的近红外光成像，覆盖的波长是普通可见光的2倍到4倍。该地图将显示比现有红外全天空调查暗40倍的物体。此外，同一地区的可见光（近紫外到红色）图像将由其他宽视场望远镜拍摄，以提供9种颜色的综合调查。由此产生的天空地图将产生一个包含超过1000万个星系和数百万颗恒星的目录，其中包含9色信息。天文学家将把这些用于许多目的：对星系和恒星的分布进行统计分析，特别是制作遥远星系分布的三维地图;用望远镜在其他波长上探测到的物体;以及寻找非常罕见的物体，如最遥远的类星体，因为它们具有不同于正常恒星的特殊颜色。
