天文学家在银河系附近发现了一个潜在的“暗银河系”,其名称为AC G185.0-11.5,主要由暗物质组成。 Astronomers have identified a potential "dark galaxy" near the Milky Way, named AC G185.0-11.5, mostly made of dark matter. 利用中国的大型望远镜探测到这一罕见的发现,其特征是一个没有恒星的旋转气体磁盘,表明它可以成为研究暗物质在银河系形成中的作用的重要实验室。 This rare discovery, detected using China's large telescope, features a rotating gas disk without stars, suggesting it could be a significant laboratory for studying dark matter's role in galaxy formation. 这一发现还可能有助于解释宇宙学中“失踪的卫星问题”的原因。 The finding might also help explain the "missing satellite problem" in cosmology.
