Milky Way over Maunakea

Explanation: Have you ever seen the band of our Milky Way Galaxy? In a clear sky from a dark location at the right time, a faint band of light becomes visible across the sky. Soon after your eyes become dark adapted, you might spot the band for the first time. It may then become obvious. Then spectacular. One reason for your growing astonishment might be the realization that this fuzzy swath, the Milky Way, contains billions of stars. Visible in the featured image, high above in the night sky, the band of the Milky Way Galaxy arcs. Also visible are the colorful clouds of Rho Ophiuchi on the right, and the red and circular Zeta Ophiuchi nebula near the top center. Taken in late February from Maunakea, Hawaii, USA, the foreground telescope is the University of Hawaii’s 2.2-Meter Telescope. Fortunately, you don’t need to be near the top of a Hawaiian volcano to see the Milky Way.

说明: 你看过银河系的中央盘面吗？从有清朗天空的幽暗地点看出去，如果时间恰好的话，可见到一道横贯天际的淡白光带。尤其当你的视觉适应暗处之后，可能让你今生首次看到这道光带，而在你的感受中，银河或许从悄然浮现，进一步深化成震撼。你的震撼感，也许是来自意识到这道弥漫的银河，竟然是由数十亿颗恒星聚合而成。于这幅主题影像里清楚可见的，还有悬在夜空中的弧状银河系盘面、右侧色彩缤纷的心宿增四星云（Rho Ophiuchi）、及顶缘附近红环状的天市右垣十一星云（Zeta Ophiuchi nebula）。在这张2月底摄于美国 夏威夷州基亚山的影像，前景的圆顶建物是夏威夷大学的2.2米望远镜。万幸的是，你不必冒着酷寒伫足于高耸的夏威夷火山顶峰，就能看到银河。
