1.We present H and K s polarimetric images in a ～5′ field of star forming region NGC7538. The polarimetric images reveal the complex structure of infrared nebulosities and clusters of young stars, associated with the bright infrared sources IRS 1 11. The polarization pattern in the IRS 1 3 nebula shows a dominant illumination from deeply embedded source IRS 1. The morphology of the nebula can be modeled by a low extincted bubble enclosed by redder and highly polarized shell.
介绍恒星形成区NGC7538的H和Ks波段偏振成像的观测结果．近5′视场的偏振图像揭示了与亮红外源IRS1?11成协的年轻星团和红外星云的复杂结构．IRS1?3星云的偏振图像表明星云的近红外辐射主要来自对深埋红外源IRS1的反射；
2.Right to the crux is the Eta Carina Nebula, one of the most beautiful nebula in the night sky.
南十字右方为船底座的海山二星云，也是十分壮观的天体。
3.The whole Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years.
这个猎户座星云-包括马头星云，将在未来的十万年间渐渐地消散。
4.While the Orion Nebula and belt stars are easy to see with the unaided eye, emission from the extensive interstellar gas is faint and much harder to record, even in telescopic views of the nebula-rich complex.
猎户座大星云和腰带星是肉眼即可见的天体，不过广垠的暗淡云气则很难成像，甚至大部份这片云气遍布区域的望远镜影像也是如此。
5.A similar dark nebula in the Northern Hemisphere near the constellation Cygnus.
黑色星云北半球接近天鹅座的一种类似黑色星云
6.reflection nebula
反射星云
7.A powerful telescope can resolve a nebula into stars .
一架高性能的望远镜能从星云中分辨出星球来。
8.Unlike the rapidly rotating neutron stars in the Crab Nebula and Vela supernova remnants that are surrounded by dynamic magnetized clouds of electrons called pulsar wind nebulas, this neutron star is quiet, faint, and so far shows no evidence for pulsed radiation.
与蟹状星云和船帆座超新星遗迹中被磁化电子云（脉冲星风星云）环绕的高速自转中子星不同，这颗中子星安静而虚弱，目前为止，没有显示脉冲辐射的迹象。
9.Located nearly 1,500 light-years away from Earth, the Orion nebula is the brightest spot in the sword of the hunter constellation.
距离地球约1500光年，猎户座星云成为猎户星座宝剑上最明亮之处。
10.Boomerang Nebula - the coolest place in the Universe?
宇宙中最冷的地方？
