英文原文:Explanation: 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 cluster s 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 说明: 如同蜜蜂一般,恒星围绕着明亮的球状星团M15的中心盘旋。 这个由超过10万颗恒星[2]组成的中心球体,是银河系早期[3]的遗迹,至今仍持续围绕银河系中心[4]运行。 M15[5]是现存约150个球状星团[6]之一,它以仅需双筒望远镜[7]即可轻易观测而闻名,其中心拥有已知最密集的恒星群[8]之一,并且包含大量的变星[9]和脉冲星[10]。 这张 M15 的主题图像是由多张超长时间[11]曝光照片成合成的,总共曝光时间长达122小时,因此可呈现出在这颗巨大恒星球体前方的微弱气体和尘埃[12]。 M15[13]位于星座[14]飞马座方向,距离我们约 35,000光年[15]。
