新的研究揭示了星系周围的空间 星系循环利用星体元素 包括碳元素 返回星系 New study reveals space around galaxies recycles star elements, including carbon, back into galaxies.

研究人员发现,环星系周围的空间 -- -- 环星体 -- -- 的环星介质,表现得像一个传送带,循环利用恒星制造的元素,如碳返回星系以形成新的恒星和行星。 Researchers have found that the circumgalactic medium, a space surrounding galaxies, acts like a conveyor belt recycling star-built elements like carbon back into galaxies to form new stars and planets. 这一发现公布在《天体物理日记》上,表明我们体内的碳可能来源于银河系外的恒星,而后又被带回星系。 This discovery, published in the Astrophysical Journal Letters, shows that the carbon in our bodies likely originated from stars outside our galaxy before being drawn back in. 该研究强调了这种回收过程对银河系进化和恒星形成的重要性。 The study highlights the importance of this recycling process for galaxy evolution and star formation.
