Spiral galaxy ESO 137-001 hurtles through massive galaxy cluster Abell 3627 some 220 million light years away. The distant galaxy is seen in this colorful Hubble/Chandra composite image through a foreground of the Milky Way’s stars toward the southern constellation Triangulum Australe. As the spiral speeds along at nearly 7 million kilometers per hour, its gas and dust are stripped away when ram pressure with the cluster’s own hot, tenuous intracluster medium overcomes the galaxy’s gravity. Evident in Hubble’s near visible light data, bright star clusters have formed in the stripped material along the short, trailing blue streaks. Chandra’s X-ray data shows off the enormous extent of the heated, stripped gas as diffuse, darker blue trails stretching over 400,000 light-years toward the bottom right. The significant loss of dust and gas will make new star formation difficult for this galaxy. A yellowish elliptical galaxy, lacking in star forming dust and gas, is just to the right of ESO 137-001 in the frame.

✨ 螺旋星系 ESO 137-001 正以近 700 萬公里每小時的速度穿越距離地球約 2.2 億光年的巨大星系團 Abell 3627。在這幅色彩繽紛的哈伯（Hubble）/ 詹達（Chandra）合成圖像中，我們透過位於南天三角洲星座的銀河系前景觀察到這個遙遠的星系。當 ESO 137-001 在星系團的熱、稀薄的星際介質中高速移動時，拉姆壓力克服了星系自身的引力，導致其氣體和塵埃被剝離。哈伯的近可見光數據顯示，明亮的星團在剝離的物質中形成，沿著短暫的藍色拖曳條紋展現出來。詹達的 X 射線數據展示了被剝離的加熱氣體的巨大範圍，顯示出延伸超過 40 萬光年的淡藍色拖曳。這次顯著的氣體和塵埃損失將使該星系的新星形成變得困難。而在 ESO 137-001 的右側，我們還可以看到一個缺乏星形成塵埃和氣體的黃色橢圓星系。
