星云状物

You can still see the gas or nebulosity in big telescopes and the right filters.

用大望远镜和适度的滤色镜，你也可以看到那些气体或星云状物。

The possibility that stellar evolution of either Sirius A or Sirius B could be responsible for this discrepancy is rejected by astronomers on the grounds that the timescale of thousands of years is too short and that there is no sign of the nebulosity in the system that would be expected had such a change taken place.

恒星演化的可能性要么是天狼星A要么是天狼星B造成的差异，地球上科学家不认可这种看法，数千年的时间刻度太短，在系统内没有星云状物的迹象，在这系统内认为这可能性会发生的。

To the left of the Horsehead Nebula, visible as the small dark indentation near the image top, is the photogenic Flame Nebula.

在左侧的马头星云，靠近图像的顶部，可见小而黑暗的锯齿状物，那便是上镜的火焰星云。

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。

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）。
