The Milky Ring

Explanation: An expanse of cosmic dust, stars and nebulae along the plane of our Milky Way galaxy form a beautiful ring in this projected all-sky view. The creative panorama covers the entire galaxy visible from planet Earth, an ambitious 360 degree mosaic that took two years to complete. Northern hemisphere sites in western China and southern hemisphere sites in New Zealand were used to collect the image data. Like a glowing jewel set in the milky ring, the bulge of the galactic center, is at the very top. Bright planet Jupiter is the beacon just above the central bulge and left of red giant star Antares. Along the plane and almost 180 degrees from the galactic center, at the bottom of the ring is the area around Orion, denizen of the northern hemisphere’s evening winter skies. In this projection the ring of the Milky Way encompasses two notable galaxies in southern skies, the large and small Magellanic clouds.

说明: 在这幅全天投影图里，我们银河系盘面上的广袤宇宙尘埃、恒星和星云，形成一个美丽的圆环。这个颇具创意、费时2年才完成的360度的全景图，呈现地球能见到的所有银河景观。收集这些影像数据的地点，分别座落在中国西部及南半球的新西兰。酷似戒指晶亮钻石的的银河中心鼓核，则位在银河环的顶部。影像中，木星是银河鼓核上方及红巨星心宿二左侧的明亮天体。与鼓核相距180度的银河环底部，为北半球冬季星空中猎户座附近的区域。在这幅投影图里，银河环以内值得一提的天体，有南天的大与小麦哲伦星系。
