gas dust cloud

基本解釋

It consists of a dusty, doughnut-shaped cloud of gas and dust that feeds a central supermassive black hole.
它由多塵的環(huán)狀氣體云和不斷進入中心巨型黑洞的塵埃組成。
A large cloud of gas and dust begins to congeal gravitationally, starts rotating, and eventually flattens into an object called a protostellar disk.
由氣體和塵埃構(gòu)成的巨大云團在引力的作用下開始凝縮，并且開始旋轉(zhuǎn)，最終變平成為平面狀物體，這種物體被稱為原恒星盤。

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.
這個劇烈消耗的階段是很容易被觀測到的，因為這些被丟棄的能量把那些進入黑洞的氣體和塵埃變成了一個灼熱的云團。

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.
