It appears as a faint bluish haze right of center against a background of stars in the loosely grouped Alpha Persei Moving Cluster .

在这幅图上，分离的彗尾创造出一个反射星云的幻象——在图片中央靠右处，一层蓝色的朦胧薄雾缭绕在英仙座阿尔法移动星团构成的疏散恒星背景之间。

In this image, the separated tail creates the illusion of a reflection nebula. It appears as a faint bluish haze right of center against a background of stars in the loosely grouped Alpha Persei Moving Cluster.

在该照片里，彗尾产生了一个反射星云的效果：即在背景星空衬托下，该彗尾在照片中间偏右疏散星团的地方出显出淡淡的蓝色云雾状。

In the physical sphere change is the order of existence.

在这个地球的历史上，以及许多其他的星球、卫星、星云的历史里也曾发生过许多次这类的改变。

The Rosette Nebula itself, and its massive cluster of stars, is located to the right of the picture.

玫瑰星云的本身，其庞大的恒星群，位于该图片的权利。

NASA has proposed a mission,called Constellation-X, that would build on this work by providing detailed pictures of what happens to space-time at the edges of these gravitational chasms.

NASA业已提出名为&X星云&的计划，将会通过提供这些引力深渊的边缘时空所发生现象的精细照片，完成这项工作。

There are two forces that counteract gravity to suppress the fragmentation of the cloud: thermal pressure from the heat of protostars, and turbulence, which may allow massive stars to form directly from accretion.

有两种力可以抵消引力的作用从而抑制星云的破碎：源于原恒星热量的温压，以及湍流--它可能允许大质量恒星通过吸积直接形成。

Players also determine the strength of enemy races and the amount of nebulas which clutter the starfield.

玩家同样也可以决定敌对种族的力量，以及星域中乱七八糟的星云的数量。

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 star primarily responsible for this interstellar sculpture can be found in the planetary nebula's center.

至于造成这座星际雕塑品的始作俑者，我们可以在行星状星云的中心看到此恒星的尊容。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
