Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
GLIMPSE the Milky Way

Explanation: Scroll right and gaze through the dusty plane of our Milky Way Galaxy in infrared light. The cosmic panorama is courtesy of the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) project and the Spitzer Space Telescope. The galactic plane itself runs through the middle of the false-color view that spans nine degrees (about 18 full moons) across the southern constellation Norma. Spitzer's infrared cameras see through much of the galaxy's obscuring dust revealing many new star clusters as well as star forming regions (bright white splotches) and hot interstellar hydrogen gas (greenish wisps). The pervasive red clouds are emission from dust and organic molecules, pocked with holes and bubbles blown by energetic outflows from massive stars. Intensely dark patches are regions of dust too dense for even Spitzer's infrared vision to penetrate.

红外波段拍摄的银河作者: 夜猫子 时间: 2005-12-16 20:38
看着像是许多星云的大集合啊！作者: 夜空 时间: 2005-12-16 22:52
在可见光波段里，银河系中央部分恒星的光都给尘埃给挡住了，所以在可见光里看上去银河中心部分是暗的，而红外波段则能拍得这些光，所看上就感觉亮很多了作者: 夜空 时间: 2005-12-16 22:54
可能说得不是很清楚，等有翻译了，我把翻译贴上来，大家可以找一张可见光拍的银河来对比一下的作者: 夜空 时间: 2005-12-17 00:05
