James Webb 空间望远镜探测早期星系的“外在”增长 7亿年大爆炸后 James Webb Space Telescope detects early galaxy's "inside-out" growth 700 million years post-Big Bang.

詹姆斯·韦伯太空望远镜(JWST)在大爆炸发生仅7亿年后 探测到银河系的“内外”增长。 The James Webb Space Telescope (JWST) has detected an "inside-out" growth of a galaxy just 700 million years after the Big Bang. 这个银河系比银河系小100倍, 显示恒星核心密度高, 恒星向近郊的形成越来越快。 This galaxy, 100 times smaller than the Milky Way, shows a dense star core with increasing star formation towards its outskirts. 这一史无前例的观测可增进对星系如何从气体云演变为复杂结构的理解。 This unprecedented observation may enhance understanding of how galaxies evolve from gas clouds into complex structures. 调查结果是评估和评价处协作的一部分,发表在《自然天文学》上。 The findings were part of the JADES collaboration and published in Nature Astronomy.
