gas dust cloud

基本解释

It consists of a dusty, doughnut-shaped cloud of gas and dust that feeds a central supermassive black hole.
它由多尘的环状气体云和不断进入中心巨型黑洞的尘埃组成。
A large cloud of gas and dust begins to congeal gravitationally, starts rotating, and eventually flattens into an object called a protostellar disk.
由气体和尘埃构成的巨大云团在引力的作用下开始凝缩，并且开始旋转，最终变平成为平面状物体，这种物体被称为原恒星盘。

This violent phase of consumption is the one that is readily observed, because the castoff energy turns the incoming gas and dust into a glowing cloud.
这个剧烈消耗的阶段是很容易被观测到的，因为这些被丢弃的能量把那些进入黑洞的气体和尘埃变成了一个灼热的云团。

Mr. EICHER: We can't really understand the solar system and how it got going unless we can really understand the origins and the conditions that happened when the solar nebula, this cloud of gas and dust, contracted down and the star turned on and the planets got going.
