Explanation: In brush strokes of interstellar dust and glowing gas, this beautiful skyscape is painted across the plane of our Milky Way Galaxy near the northern end of the Great Rift and the constellation Cygnus the Swan. Composed over a decade with 400 hours of image data, the broad mosaic spans an impressive 28×18 degrees across the sky. Alpha star of Cygnus, bright, hot, supergiant Deneb lies at the left. Crowded with stars and luminous gas clouds Cygnus is also home to the dark, obscuring Northern Coal Sack Nebula and the star forming emission regions NGC 7000, the North America Nebula and IC 5070, the Pelican Nebula, just left and a little below Deneb. Many other nebulae and star clusters are identifiable throughout the cosmic scene. Of course, Deneb itself is also known to northern hemisphere skygazers for its place in two asterisms, marking a vertex of the Summer Triangle, the top of the Northern Cross.

说明: 这幅以星际尘埃和辉光气体为笔触的美丽星空影像，呈现我们银河系盘面大裂缝（大暗隙）北端附近及天鹅座的景观。从摄于超过10年期间、总曝光时数为400小时的影像数据，组合而成的这幅广袤拼接影像，涵盖了天空28×18度的区域。其中，天鹅座α星——明亮炽热的超巨星天津四，位在影像的左侧。而繁星及明亮气体云群集的天鹅座，也是北煤袋星云、恒星形成与发射区NGC 7000（北美洲星云）、及天津四左下方IC 5070（鹈鹕星云）的家园。此外，这片宇宙天区里，还散布着许多可辨识的星云和星团。对北半球的观星者来说，天津四是组成二个著名星官的重要天体，它分别是北十字的顶点和夏三角的一个端点。
