The Galaxy Above

Explanation: Have you contemplated your home galaxy lately? If your sky looked like this, perhaps you’d contemplate it more often! The featured picture is actually a composite of two images taken last month from the same location in south Brazil and with the same camera — but a few hours apart. The person in the image — also the astrophotographer — has much to see in the Milky Way Galaxy above. The central band of our home Galaxy stretches diagonally up from the lower left. This band is dotted with spectacular sights including dark nebular filaments, bright blue stars, and red nebulas. Millions of fainter and redder stars fill in the deep Galactic background. To the lower right of the Milky Way are the colorful gas and dust clouds of Rho Ophiuchus, featuring the bright orange star Antares. On this night, just above and to the right of Antares was a bright planet Jupiter. The sky is so old and so familiar that humanity has formulated many stories about it, some of which inspired this very picture.

说明：最近有没有对银河系陷入沉思？如果你的天空是上图这个样子，也许你会经常冥想它的存在。这张影像实际上是上个月在巴西同一地点使用同一台相机，但间隔几小时拍摄的两张影像叠加而成。影像中的人（摄影者）头顶的银河系有很多看点。左下侧拉伸的是银河系的中央地带。明亮的蓝色恒星、暗星云、红色星云点缀着这片壮丽的银河系中央区域。在银河背景中，还可以看到数百万黯淡红色恒星。右下侧有蛇夫座的多彩气体和尘埃云，它点缀着亮橙色的恒星心宿二。而位于心宿二的右侧、位于影像上方的是明亮的木星。古老而熟悉的天空，引导人类形成了许多与之有关的故事和传说，也许其中有一些灵感便来源于上图的这片美景。
