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 very center of the Milky Way was only recently found capable of forming newborn stars. The galactic center lies some 26,000 light-years away, toward the constellation Sagittarius. At that distance, this picture spans about 900 light-years.

在我們的銀河系中心,由於雲層的遮擋,光學望遠鏡無法探測到它的真面目。不過,在這幅驚人的畫面中,斯皮策太空望遠鏡的紅外線相機穿透了大部分塵埃,揭示了擁擠的銀河中心區域的恆星。這幅由多張小快照拼接而成的詳細假色圖像顯示了年長、冷卻的恆星以藍色調呈現,而紅色發光的塵埃雲則與年輕、炙熱的恆星在恆星形成區有關。銀河中心的核心地帶最近才被發現能夠形成新生恆星。銀河中心距離地球約26,000光年,位於人馬座的方向。在這個距離下,這幅圖片的範圍大約是900光年。
