一条遥远的恒星流可能为暗物质提供新线索

天文学家正致力于揭开暗物质的神秘面纱，这种物质虽不可见，却能通过引力效应影响普通物质。哥本哈根大学的研究团队发现了一条延伸超过3,000光年的恒星流，其形态似乎受到了遥远星系中暗物质的影响。

Dark matter continues to challenge astronomers as they work to solve the mystery of this so-far-unseen material that permeates the Universe. It's not that the stuff doesn't exist. It does, but we just can't see it. The only way it can be detected is by its gravitational effects on ordinary matter. A team of researchers led by University of Copenhagen PhD student Julie Kiel Holm has found a stream of stars stretching out more than 3,000 light-years from a globular cluster that appears to have been shaped by dark matter in a distant galaxy.
