多国天文学家27日宣布，他们发现了宇宙中迄今最古老的一个“太阳系”。它诞生在宇
宙的“黎明时分”，至少5颗地球大小的行星围绕着一颗类似太阳的恒星运行。这项发
现说明，类地行星的形成遍布宇宙的几乎整个历史，为寻找外星生命提供新的线索。
参考消息网1月30日报道法媒称，根据一项新研究，天文学家发现了已知最大的“太阳
系”，巨大的行星围绕恒星运行一周需要近100万年。
法新社1月27日电称，科学家们此前一直认为这是一颗自由浮动的孤独行星，并无“归
属”。现在，他们已经将它与约1万亿公里以外的一颗恒星联系起来。
研究人员通过观察发现这两颗星在协调运动，而且它们到太阳的距离都是大约104光年。
研究报告的第一作者、英国赫特福德郡大学的尼尔·迪肯说：“这是迄今为止发现的范
围最广的星球系统。天文学界8年前就知道这两颗星球的存在，但此前没有人将两者联
系起来。”
迪肯说：“这颗行星并不像我们起初认为的那么孤独，但这当然是一种非常遥远的关系
。”
研究报告26日刊登在英国《皇家天文学会月刊》上。

Explanation: The bulging center of our Milky Way Galaxy, dark cosmic clouds, the thin
galactic plane, and even nearby galaxies are easy to spot in this sky view. But each pixel in
the digital image is actually based on star counts alone -- as derived from the Two Micron
All Sky Survey (2MASS) database. In 2001, the 2MASS project completed a ground-based
survey of the entire sky and cataloged upwards of 250 million stars. Their full all-sky picture
