哇！韦布空间望远镜观测到的古老星系比预想的质量大得多

韦布空间望远镜在早期宇宙中发现了质量惊人的星系，挑战了现有的星系形成理论。最新研究表明，这些星系中隐藏着大量小质量星，其实际质量比此前估计的还要大。

When the JWST peered into the ancient Universe, it found surprisingly massive galaxies. These galaxies were so massive they challenged our understanding of how quickly galaxies can assemble. But new research says that multitudes of low-mass stars are hiding in these galaxies, and they're actually even more massive than we thought. When will it end?
