英文原文:Explanation: Is there a monster in IC 1396 ? Known to some as the Elephant's Trunk Nebula , parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human . The only real monster here, however, is a bright young star too far from Earth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the featured image. Jets and winds of particles emitted from this star are also pushing away ambient gas and dust . Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a much larger region on the sky than shown here, with an apparent width of more than 10 full moon s. 说明: IC 1396[2] 里有怪物吗? 这片恒星形成区被一些人称为象鼻星云[3],部分气体和尘埃[4]云可能呈现出令人毛骨悚然的形态,有些甚至近似人形[5]。 然而,这里唯一真正的怪物[6]是一颗距离地球[7]非常遥远的明亮年轻恒星[8],不会对我们造成伤害。 这颗恒星发出的高能光[9]正在侵蚀图片顶部附近的黑暗彗星状云球[10]之尘埃。 这颗恒星发射的喷流[11]和粒子风[12]也在推开周围的气体和尘埃[13]。 距离地球近3,000光年[14]相对暗淡的IC 1396复合体[15]在天空中覆盖的区域比这里显示的要大得多,其视宽度超过10个满月[16]。
