IT之家2月6日消息,据央视新闻报道,被誉为“中国天眼”的500米口径球面射电望远镜(FAST),已发现超740颗脉冲星。FAST总工程师姜鹏表示,截至目前,FAST发现的脉冲星总数已经达到740颗以上

IT之家 2 月 6 日消息,据央视新闻报道,被誉为 “中国天眼”的 500 米口径球面射电望远镜(FAST),发现超 740 颗脉冲星


FAST 总工程师姜鹏表示,截至目前,FAST 发现的脉冲星总数已经达到 740 颗以上。随着脉冲星发现数量的不断增加,科学家们可以在未来通过脉冲星测试阵列,寻找引力波存在的证据,或者通过脉冲星测时,建立自主可控的时间基准体系

姜鹏说道:“这 700 多颗(脉冲星),它只是给你提供了一种条件。你有这个发现能力,你才有可能发现我们期待发现的这种奇异的脉冲星。我们更期待的是发现一种特别种类的脉冲星,比如是跟黑洞相互配对的这种双星系统,那我们就可以在更极端的引力场条件下,检验爱因斯坦相对论的正确性。”

IT之家了解到,500 米口径球面射电望远镜(Five-hundred-meter Aperture Spherical radio Telescope)利用贵州喀斯特地区的洼坑作为望远镜台址建造的,由我国天文学家南仁东于 1994 年提出构想,历时 22 年建成,于 2016 年 9 月 25 日落成启用,是目前世界上口径最大,灵敏度最高的单口径射电望远镜,拥有 30 个标准足球场大的接收面积。
