詹姆斯韦伯太空望远镜JWST揭开了宇宙再电离的秘密 James Webb Space Telescope JWST Reveals Secrets of Cosmic Re-ionization

宇宙大爆炸后不到十亿年，一些极低质量的星系就已经出现了。它们是如何形成的？它们对宇宙的演化有什么影响？这些问题一直困扰着天文学家，因为这些星系太暗，太遥远，难以观测。但是，最新的技术突破让我们有了新的眼光。詹姆斯-韦伯太空望远镜（JWST）利用了一种特殊的现象，成功地捕捉到了这些星系的光谱。这一发现揭示了宇宙再电离的起源，是我们对宇宙认知的重大突破。

Less than a billion years after the Big Bang, some very low-mass galaxies have appeared. How did they form? What impact do they have on the evolution of the universe? These questions have always plagued astronomers because these galaxies are too faint and too distant to observe. But the latest technological breakthrough has given us fresh eyes. The James Webb Space Telescope (JWST) has managed to capture the spectra of these galaxies using a special phenomenon. This discovery reveals the origin of cosmic re-ionization and is a major breakthrough in our knowledge of the universe.
