说明：由于朦胧的尘埃和气体存在，我们银河系的中心逃过了光学望远镜的善于捕捉的眼睛。但在这绚丽的景象中，斯皮策太空望远镜的红外线相机，透过大部分尘埃，揭示了银河系中心区域拥挤的恒星。一张由许多小的快照形成的详细的假色照片中，显示了带蓝色的区域中年长的，暗冷恒星。在恒星温床中略带红色的发光尘埃云与年轻的炽热恒星有关。恒星中心位于人马座中，距离有2.6万光年远。上面图像所覆盖区域的距离大小约900光年。[/center]

Explanation: The center of our Milky Way Galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas. But in this stunning vista, the Spitzer Space Telescope's infrared cameras, penetrate much of the dust revealing the stars of the crowded galactic center region. A mosaic of many smaller snapshots, the detailed, false-color image shows older, cool stars in bluish hues. Reddish glowing dust clouds are associated with young, hot stars in stellar nurseries. The galactic center lies some 26,000 light-years away, toward the constellation Sagittarius. At that distance, this picture spans about 900 light-years[/center]
