星云

This beautiful telescopic view combines a composite color image with narrow band data that isolates light from hydrogen and oxygen atoms in the wind-blown nebula.

这张美丽的望远镜影像是一张色彩合成的窄波段数据影像，分离了这个星云内氢和氧原子发出的光。

Of course , in this well-studied example of a planetary nebula , the glowing material does not come from planets .

Of course , in this well-studied example of a planetary nebula , the glowing material does not come from planets .

当然，在这个被细致地研究过的行星状星云样本中，炽热的物质并非来自行星，而是一颗正在死亡的太阳型恒星向外扩散的气壳。

The inner filaments visible above are being ejected by strong wind of particles from the central star. The outer disk contains unusual light-year long orange filaments.

影像中清楚可见的星云内层丝状结构，是强烈恒星风所抛出的的中心星物质，而外层碟状区，有许多长度有一光年长的奇特橘色指状物。

The long exposure used to create the above photograph makes the light from the left, reflected from Phoenix, Arizona, USA, appear like a sunset. Far in the distance, however, are star clouds from the disk of our Milky Way Galaxy.

亚利桑那州凤凰城的灯光从云层反射，造成类似日落时分的景象；遥远的后方则为我们银河系盘面上的星云。

Spiral galaxy disks and primordial Solar nebula are composed of gaseous disk and star disk.

How big they get depends on their distance from the star and the density and composition of the protoplanetary nebula.

他们的形体能达到多大取决于他们离恒星的距离和原行星星云的组成。

The China-Born, M.I.T. and Harvard educated astrophysicist laid the theoretical foundations for spiral structures in galaxies, density waves and star formation. These theories were later validated and became important cornerstones in astronomy.

这位中国出生，曾於麻省理工及哈佛接受教育的天体物理学家，致力建构有关银河、星云与星体盘旋结构的理论基础，这些理论后来也得到世界确认并成为天文研究的重要基石。

Stellarium has many data files containing such things as star catalogue data, nebula images, button icons, font files and configuration files.

Stellarium 含有很多数据文件用以存放星表数据、星云图片、按钮图标、字体和配置等等。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
