英文原文:Explanation: What powers are being wielded in the Wizard Nebula? Gravitation strong enough to form stars, and stellar winds and radiations powerful enough to create and dissolve towers of gas . Located only 8,000 light years away, the Wizard nebula, featured here, surrounds developing open star cluster NGC 7380 . Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer . The active star forming region spans 100 about light years , making it appear larger than the angular extent of the Moon . The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia ( Cepheus ). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun . 说明: 巫师星云中蕴藏着怎样的力量?强大的引力足以形成恒星,而恒星风[3]和辐射则强大到可以创造和消散气体塔[4]。巫师星云距离我们仅有8,000光年,环绕着正在形成的疏散星团 NGC 7380[5]。视觉上,恒星、气体和尘埃的相互作用创造出一个形状,有些人觉得[6]它像一个虚构的中世纪巫师[7]。 这个活跃的恒星形成区域横跨约100光年[8],使其看起来比视角范围[9]更大,甚至超过月球[10]。巫师星云[11]可以用小型望远镜在埃塞俄比亚国王星座(仙王座[12])的方向找到。虽然星云可能只持续[13]几百万年,但其中一些正在形成的恒星可能会比我们的太阳[14]更长寿。
