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.

什么东西这么漂亮！

红外波段拍摄的银河

看着像是许多星云的大集合啊！

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

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

说明：将滚轴拖到右边，就会看见红外波段上布满尘埃的银道面。盘面中部对银河系遗迹的红外特殊巡天（GLIMPSE）计划与Spitzer太空望远镜共同合作，其成果就是这张广阔的全景图。这张伪彩色图横跨南天矩尺座，跨越天区的范围约是9度（约是18个满月的大小），而银道面则通过图的中部。Spitzer的红外相机穿过银河中大量的遮光尘埃，显示了许多新的星团、恒星形成区（明亮的白色斑点）和炽热的星际氢气（绿色的云气丝）。弥散的红色云块是发光的尘埃和有机分子，其上遍布着由大质量恒星发出的高能外流所吹出的洞和气泡。极其黑暗的小片区域是尘埃特别浓密的地方，那里即使是Spitzer的红外眼也不能穿透。（翻译：刘媛媛

红外波段的银河怎么看不到银心呢？
