一个幽灵星系,99.9%的暗物质, 利用恒星群和先进的望远镜 在距离2.5亿光年远的地方被发现。
A ghost galaxy, 99.9% dark matter, was found 250 million light-years away using star clusters and advanced telescopes.
一个由加拿大牵头的团队在距离2.5亿光年的距离外发现了CDG-2,一个“幽灵星系”2.5亿光年,主要由暗物质组成,由于其微弱的亮度几乎是看不见的——仅相当于500万颗恒星。
A Canadian-led team has discovered CDG-2, a "ghost galaxy" 250 million light-years away, composed mostly of dark matter and nearly invisible due to its faint brightness—equivalent to just 5 million stars.
研究人员利用哈勃,欧几里德和苏巴鲁望远镜的数据通过四个轨道球状星团确定了它,这表明该星系可能99.9%是暗物质,过去的相互作用剥夺了形成恒星的物质.
Using data from Hubble, Euclid, and the Subaru Telescope, researchers identified it through four orbiting globular clusters, suggesting the galaxy is likely 99.9% dark matter, stripped of star-forming material by past interactions.
这一发现突显了暗物质在宇宙结构中的主导作用,并推进了天体统计学,为宇宙的看不见组成部分提供了新的线索。
The finding highlights dark matter’s dominant role in cosmic structure and advances astrostatistics, offering new clues about the universe’s unseen components.
