哈勃在三重星系中 发现一个稀有的"蓝色潜星"恒星 提供对恒星进化的洞察力 Hubble spots a rare "blue lurker" star in a triple system, offering insights into star evolution.

美国航天局的哈勃太空望远镜 在M67星群中发现了一颗稀有的“蓝色潜星”恒星, 距离2800光年远。 NASA's Hubble Space Telescope has identified a rare "blue lurker" star in the M67 star cluster, about 2,800 light-years away. 这颗恒星是三星星系统的一部分, 由于其快速旋转和可能与其他恒星合并, 使恒星更热、更亮, 因而异常不寻常。 Part of a triple-star system, this star is unusual due to its fast spin and likely mergers with other stars, making it hotter and brighter. 这一发现为多重恒星系统的复杂演变提供了宝贵的洞察力。 This discovery offers valuable insights into the complex evolution of multiple star systems.
