　　图中红色圈点内的绿点为发射FRBs的矮星系。<\/p>\n

　　国际在线专稿：据新加坡《联合早报》1月5日报道，当地时间周三（4日），美国天文学协会在美国得克萨斯州召开年度会议称，天文学家首次发现，10年前探测到的神秘外太空无线电波，很可能来自距离地球约30亿光年的矮星系。<\/p>\n

　　据该报道，自2007年有记录以来，人类已发现18次这类“快速电波爆发”（FRBs）。当时有人认为这是外星人试图与地球人联络的信号。<\/p>\n

　　团队成员之一、加拿大麦基尔大学的德鲁卡博士（Dr. Shriharsh Tendulkar）指出，在知道FRBs与地球的距离前，科学家曾提出多个可能的解释，认为信号源于银河系内或附近，“但我们现在已排除这些可能性”。<\/p>\n

　　报道称，“快速电波爆发”只要闪现一毫秒，就能发出太阳一万年所发出的能量，但形成原因至今仍不得而知。<\/p>\n

　　科学家说，虽然新发现不能解答电波的成因，但至少缩小了讨论范围。初步预计，可能是源于被恒星爆炸后碎片包围的磁星，或是从巨型黑洞边缘射出的物质。<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[],"class_list":["post-331836","post","type-post","status-publish","format-standard","hentry","category-science_technology_education"],"_links":{"self":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/posts\/331836","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/comments?post=331836"}],"version-history":[{"count":0,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/posts\/331836\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/media?parent=331836"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/categories?post=331836"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sandiegochinesepress.com\/press\/wp-json\/wp\/v2\/tags?post=331836"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
