看看夜空中最上镜的区域之一,令人印象深刻。我们的银河系带沿着左下角的对角线运行,而彩色的蛇夫座星云复合体在中央的右边可见,而大的红色圆形蛇夫座星云出现在顶部附近。一般来说,红色来自于在激发态氢气的光线下发光的星云,而蓝色标志着星际尘埃优先反射明亮的年轻恒星的光线。厚厚的灰尘通常呈深褐色。夜空中出现了许多标志性的天体,包括(你能找到它们吗?)明亮的心宿二星,球状星团M4和蓝马头星云。这张广角合成照片是去年6月在南非拍摄的,历时17个多小时。探索你的宇宙:随机APOD生成器

Behold one of the most photogenic regions of the night sky, captured impressively. Featured, the band of our Milky Way Galaxy runs diagonally along the bottom-left corner, while the colorful Rho Ophiuchi cloud complex is visible just right of center and the large red circular Zeta Ophiuchi Nebula appears near the top. In general, red emanates from nebulas glowing in the light of excited hydrogen gas, while blue marks interstellar dust preferentially reflecting the light of bright young stars. Thick dust usually appears dark brown. Many iconic objects of the night sky appear, including (can you find them?) the bright star Antares, the globular star cluster M4, and the Blue Horsehead nebula. This wide field composite, taken over 17 hours, was captured from South Africa last June. Explore Your Universe: Random APOD Generator
