这次发现首次证实了“千新星”爆炸,确认了双中子星合并是宇宙中最重的元素的来源之一,比如金和铀。
5. This is the first binary neutron star pair confirmed outside of our own Milky Way galaxy, and this is the closest to Earth that astronomers have seen a gamma ray burst.
这是银河系外首次得以证实的一对中子星,也是天文学家观测到伽马射线暴距离地球最近的一次。
6. The gravitational wave signals from GW170817 have enabled scientists to measure the expansion rate of the universe in a completely new way.
来自此次GW170817观测的引力波使科学家可以用全新的方式测量宇宙的膨胀率。
7. The partnership between LIGO and Italy-based Virgo allowed telescopes to rapidly turn their attention towards the area of sky where the neutron stars collided.
激光干涉引力波天文台(LIGO)和意大利的处女座引力波探测器(Virgo)让无数望远镜迅速调转方向,对准这一片天空,观测两个中子星合并。
8. This event presents the strongest evidence to date for the detection of a gamma-ray burst off-axis, which means the cone emission from the explosion is not pointed directly at Earth.
此次观测为伽马射线暴轴偏移提供了有史以来最强有力的证据,也就是说伽马射线暴产生的锥状发射不是直接对准地球的。
