1·Next door, though, lives a giant molecular cloud, visible to the right.

紧邻在旁的是一个巨大分子云，在照片的右下角可见。

2·They tower above the surface of a molecular cloud on the edge of the nebula.

它们从星云底部的一片分子云表面耸立而出。

3·The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2, 400 light-years or so away.

这个名为Mon R2的巨大的分子云离我们非常近，据估计只有大概2400光年。

4·The spectacular Horsehead Nebula is actually a projection of cold gas and dust extending from the dense Orion Molecular Cloud.

引人注目的马头星云实际上是低温气体和自稠密的猎户座分子云延伸而来的尘埃相互作用而形成的突起物。

5·The process blasted out material to form the bubble structure of glowing gas against denser material in a surrounding molecular cloud.

这个过程形成的炽热气泡结构恰好可以抵御周围分子云中密度更高物质的压力。

6·The current picture is that stars are formed during the collapse of a large enough self gravitating interstellar molecular cloud.

目前了解的恒星形成的一个基本图象是，恒星是由一个足够大质量的星际分子气体云在其自引力作用下塌缩而形成。

7·The complex is called the Vela Molecular Cloud Ridge, and may form part of the edge of the Orion spiral arm spur in the Milky Way galaxy.

这片复合区域被称为船帆分子云脊（Vela Molecular Cloud Ridge），它可能参与形成了猎户座悬臂的边缘部分。

8·The Nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away.

在这片离地球1500光年远的广大星际分子云的边缘，有一些发光的云气包围著年轻亮星。

9·The emission nebula is found near the edge of an otherwise dark large molecular cloud in the southern constellation Ara, about 4, 000 light-years away.

这个发射星云在南天星座天坛座另一个巨大的暗分子云的边缘被发现，离我们约4000光年。

10·A molecular cloud is a region containing cool interstellar gas and dust left over from the formation of the galaxy and mostly contains molecular hydrogen.

分子云是一个包含冷却星际气体和尘埃的区域，这些气体和尘埃是星系形成之后的残留物，主要由氢分子组成。
