Collapsing interstellar cloud reverses its gravitational infall and expands outward into the relatively quiescent interstellar environment.
坍縮的星際雲克服向內的引力而向外膨脹到較寧靜的星際環境中去。 -
The contraction of a cool interstellar gas cloud can proceed in a variety of ways.
一個冷的星際氣體雲的收縮，可以通過許多不同的方式來進行。 -
Before the interstellar cloud contracts, it was very cold and dim. thus, the cloud is represented by a point at the right in the h - r diagram
在星際雲收縮之前，它非常冰冷，所以在這個階段，星際雲會位於赫羅圖上一個極右的位置。 -
Upon contraction under its own gravity, the interstellar cloud heats up, and thus moving to the left in the diagram. note that the position of a star in the h - r diagram shows its physical properties, not its position in the sky
當星際雲收縮，它會變得越來越熱，而它在赫羅圖上的位置亦會向左移動注意：恆星在赫羅圖上的位置顯示了它們的物理特性，而非其在天空的位置。 -
Today, the crab nebula is still expanding and it will eventually dissolve in the interstellar gas cloud nearby
蟹狀星雲仍然在膨脹最終會溶入星際物質而消散。 -
The nebula ' s glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light - years away
在這片離地球1500光年遠的廣大星際分子云的邊緣，有一些發光的雲氣包圍著年輕亮星。 -
A star is formed when a cloud of gas collapses from the interstellar medium toward high density.
一個氣體雲自星際物質中坍縮，密度達到很高時，即形成了一個恆星。 -
Conventional theory suggests that it must have formed like a star from a collapsing cloud of interstellar gas
傳統的理論認為它一定像一顆恆星那樣是由一團星際氣體形成的壓縮星雲組成的。
