Astronomers have discovered a 13-billion-year-old galaxy cluster that is the earliest ever observed, according to a paper released Friday, a finding that may hold clues about how the universe developed.

The discovery of the protocluster, a collection of 12 galaxies, suggests that large cosmic structures were present in the very early stages of the universe, the researchers said. (AFP)

天文学家发现宇宙最古老星系团

英国天文学家团队9月27日发布报告称，他们日前发现了一个有着130亿年历史的星系团，这是目前人类观察到的最古老的星系团。该发现有助于科学家了解宇宙演化的过程。

据悉，该星系团共包含有12个星系，这表明在宇宙诞生的早期便存在着大型的星系结构。
