哈勃发现一个暗暗的 物质丰富的银河系候选人 距离3亿光年远 暗示着难以捉摸的暗色星系 Hubble found a dim, dark matter-rich galaxy candidate 300 million light-years away, hinting at elusive dark galaxies.

美国航天局的哈勃太空望远镜探测到一个微弱的物体, 候选暗银河2号(CDG-2), 距离大约3亿光年, 可能由至少99.9%的暗物质构成。 NASA's Hubble Space Telescope has detected a faint object, Candidate Dark Galaxy-2 (CDG-2), about 300 million light-years away, which may be composed of at least 99.9% dark matter. 它只排放到银河系亮度的0.005%, 并且只包含四个星团, 表明它将大部分恒星形成气体 丢失到附近的星系中。 It emits only 0.005% of the Milky Way’s brightness and contains just four globular clusters, suggesting it lost most of its star-forming gas to nearby galaxies. 研究人员认为,这些星团的重力绑定表明,有一种巨大的暗物质光环,支持暗星系的存在——由宇宙模型预测但从未直接观察到的虚构的、缺乏恒星的系统。 Researchers believe the clusters’ gravitational binding indicates a vast dark matter halo, supporting the existence of dark galaxies—hypothetical, star-poor systems predicted by cosmological models but never directly observed. 由多伦多大学Daili Li牵头的这一发现引进了一种新的方法,通过侧重于球状星群来探测这种难以捉摸的物体。 This discovery, led by Dayi Li of the University of Toronto, introduces a new method for detecting such elusive objects by focusing on globular clusters. 詹姆斯·韦伯空间望远镜可能进一步证实这一点,有可能增进对暗物质和银河系形成的认识。 Further confirmation may come from the James Webb Space Telescope, potentially advancing understanding of dark matter and galaxy formation.
