2022年1月26日 Stars, Dust, and Gas Near Antares Image Credit & Copyright: Mario Cogo (Galax Lux) Explanation: Why is the sky near Antares and Rho Ophiuchi so dusty yet colorful? The colors result from a mixture of objects and processes. Fine dust — illuminated from the front by starlight — produces blue reflection nebulae. Gaseous clouds whose ...
2020年10月14日 The Colorful Clouds of Rho Ophiuchi Image Credit & Copyright: Amir H. Abolfath Explanation: The many spectacular colors of the Rho Ophiuchi (oh’-fee-yu-kee) clouds highlight the many processes that occur there. The blue regions shine primarily by reflected light. Blue light from the Rho Ophiuchi star system and nearby stars reflects mo...
2020年8月7日 The Pipe Nebula Image Credit & Copyright: Jose Mtanos Explanation: East of Antares, dark markings sprawl through crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E. Barnard, the obscuring interstellar dust clouds include B59, B72, B77 and B78, seen in against the starry backgro...

2019 November 17 Young Stars in the Rho Ophiuchi Cloud Image Credit: NASA, JPL-Caltech, WISE Explanation: How do stars form? To help find out, astronomers created this tantalizing false-color composition of dust clouds and embedded newborn stars in infrared wavelengths with WISE, the Wide-field Infrared Survey Explorer. The cosmic canvas features one of the ...
2019 June 6 木星和烟斗星云 图片来源及版权：Alain Maury, Jean-Marc Mari 说明：现在，在星系丰富的星场和星云的映衬下，明亮的木星在夜空中闪耀。在这张中央银河系的彩色长焦照片中，木星压倒性的光芒在画面顶部闪耀。该场景横跨天空约20度，LDN 1773黑色的轮廓背对着星场，它们的组合勾勒出一个烟斗的颈和管形状，因此这片黑暗的星云也常被称为烟斗星云。烟斗星云是蛇夫座星云的一部分。蛇夫座星云位于450光年外，致密的气体和尘埃核心正在坍缩形成恒星。6月12日，木星在天空中的正对着太阳，距离地球只有36光分。天文爱好者或许能在天空中木星强光左下方的深色斑纹里看到蛇状星云。 The Planet and the Pipe Image Credit & Copyright: Ala...
