此一事件於2017年10月16日正式在美國的[[華盛頓特區]]和[[德國]]的[[加興]]宣佈。<ref name="SM-20171016">{{cite news |last=Cho |first=Adrian |title=Merging neutron stars generate gravitational waves and a celestial light show |url=http://www.sciencemag.org/news/2017/10/merging-neutron-stars-generate-gravitational-waves-and-celestial-light-show |date=2017-10-16 |work=Science |accessdate=2017-10-16 |archive-date=2018-07-22 |archive-url=https://web.archive.org/web/20180722053432/http://www.sciencemag.org/news/2017/10/merging-neutron-stars-generate-gravitational-waves-and-celestial-light-show |dead-url=no }}</ref><ref name="NYT-20171016">{{cite news |last=Overbye |first=Dennis |title=LIGO Detects Fierce Collision of Neutron Stars for the First Time |url=https://www.nytimes.com/2017/10/16/science/ligo-neutron-stars-collision.html |date=2017-10-16 |work=The New York Times |accessdate=2017-10-16 |archive-date=2017-10-16 |archive-url=https://web.archive.org/web/20171016143216/https://www.nytimes.com/2017/10/16/science/ligo-neutron-stars-collision.html |dead-url=no }}</ref><ref name="MN-20171016">{{cite news |last=Krieger |first=Lisa M. |title=A Bright Light Seen Across The Universe, Proving Einstein Right - Violent collisions source of our gold, silver |url=http://www.mercurynews.com/2017/10/16/a-bright-light-seen-across-the-universe-proving-einstein-right/ |date=2017-10-16 |work=The Mercury News |accessdate=2017-10-16 |archive-date=2017-10-16 |archive-url=https://web.archive.org/web/20171016140304/http://www.mercurynews.com/2017/10/16/a-bright-light-seen-across-the-universe-proving-einstein-right/ |dead-url=no }}</ref>

這份訊息最早是由[[德州大學奧斯丁分校]]的天文學家克雷格·惠勒（J. Craig Wheeler）於8月18日在[[推特]]發佈：“LIGO惊人新发现，引力波源伴有光学对应体。超乎想象！”<ref>{{cite web
