Unlike dense stars, the color of the thinner gas depends more on what's in it than its temperature.

与大密度的恒星不同，稀薄气体的颜色更多地取决于其内部物质，而不是温度。

The gas slams into the much thinner gas that is strewn between the stars, what we call the interstellar medium.

这些气体撞击成散布在恒星之间的更稀薄的气体，我们称之为星际介质。

In the case of thin gas clouds in space, the atoms are basically floating free, rarely bumping into one another.

至于天空中稀薄的气体云，其原子基本上是自由漂浮的，很少相互碰撞。

Far from stars and planets, deep space is filled with a very thin gas that does have a temperature, one that is very low.

在远离恒星和行星的地方，深空充满了一种非常稀薄的气体，这种气体的温度非常低。

A better way to think of it is all the stuff held sway by the Sun's gravity: the Sun itself, planets, moons, asteroids, comets, dust, and very thin gas.

太阳本身、行星、卫星、小行星、彗星、星尘和非常稀薄的气体。
