在閃爍的星空中，有一個叫做M15的閃亮星團，裡面有超過100,000顆星星，就像許多蜜蜂圍繞著明亮的中心。這些星星是我們銀河系早期時期的遺跡，現在還在圍繞著銀河的中心運行。M15是約150個依然存在的星團之一，用雙筒望遠鏡就能輕易看到。它的中心有著密集的星星聚集，還有很多變星和脈動星。在這幅特別的M15圖像上，經過122小時的長時間曝光，可以看到星星前面微弱的氣體和塵埃的絲絲。M15距離我們約35,000光年，位於飛馬座的方向。這真是一個美麗的宇宙秘密！

Stars, like bees, swarm around the center of bright globular cluster M15. The central ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way’s center. M15, one of about 150 globular clusters remaining, is noted for being easily visible with only binoculars, having at its center one of the densest concentrations of stars known, and containing a high abundance of variable stars and pulsars. The featured image of M15 was taken by combining very long exposures — 122 hours in all — and so brings up faint wisps of gas and dust in front of the giant ball of stars. M15 lies about 35,000 light years away toward the constellation of the Winged Horse (Pegasus). Almost Hyperspace: Random APOD Generator
