'''PKS 1302-102'''是一個擁有雙[[超大質量黑洞]]的[[類星體]]，在天球上位於[[室女座]]，距離地球3.5 × 10<sup>9</sup>[[光年]]（11亿[[秒差距]]）<ref>{{cite news | url=http://www.nytimes.com/2015/09/22/science/space/more-evidence-for-coming-black-hole-collision.html | title=More Evidence for Coming Black Hole Collision | publisher=New York Times | date=16 September 2015 | accessdate=2015-12-29 | archive-date=2015-12-17 | archive-url=https://web.archive.org/web/20151217151524/http://www.nytimes.com/2015/09/22/science/space/more-evidence-for-coming-black-hole-collision.html | dead-url=no }}</ref>。這是第一個在[[吸積盤]]內發現雙超大質量黑洞的類星體<ref name= TechTimes-2015-01-08>{{cite news |url= http://www.techtimes.com/articles/25412/20150108/scientists-prepare-for-first-observation-of-two-black-holes-merging.htm |title= Scientists Prepare For First Observation Of Two Black Holes Merging |publisher= TechTimes |date= 8 January 2015 |accessdate= 2015-01-12 |archive-date= 2015-02-09 |archive-url= https://web.archive.org/web/20150209053840/http://www.techtimes.com/articles/25412/20150108/scientists-prepare-for-first-observation-of-two-black-holes-merging.htm |dead-url= no }}</ref><ref name=Ars-2015-01-08>{{cite news |url= http://arstechnica.com/science/2015/01/supermassive-black-hole-binary-discovered/ |title= Supermassive black hole binary discovered |author= Xaq Rzetelny |date= 8 January 2015 |accessdate= 2015-12-29 |archive-date= 2015-01-11 |archive-url= https://web.archive.org/web/20150111091907/http://arstechnica.com/science/2015/01/supermassive-black-hole-binary-discovered/ |dead-url= no }}</ref>。直到2015年，PKS 1302-102是少數已知的其中一組[[雙黑洞]]所在地，是在類星體光變巡天的一組20個候選天體其中之一，也是最佳候選目標，甚至優於先前的候選天體[[OJ 287]]<ref name=SnT-2015-01-13>{{cite news |url= http://www.skyandtelescope.com/astronomy-news/black-hole-binary-en-route-merger-0113201423/ |title= Black Hole Binary En Route to Merger? |date= 13 January 2015 |author= Camille M.

==雙黑洞==
PKS 1302-102中的雙超大質量黑洞正在合併中，兩者距離約2.9×10<sup>11</sup>公里<ref name= TechTimes-2015-01-08/>，相當於太陽到[[奥尔特云]]的距離。根據計算，這兩個黑洞應在33.39億年前就已經合併，並且合併事件產生的可見光應在之後約百萬年內到達地球。兩個黑洞互繞產生周期約1884日的閃爍事件，並產生類星體約14%的輻射量。因此可以預期如果黑洞和並發生，將會釋放輻射能為[[超新星]]1億倍的巨大輻射<ref name=NYTimes-2015-01-07>{{cite news |url= http://www.nytimes.com/2015/01/08/science/in-a-far-off-galaxy-2-black-holes-dance-toward-an-explosive-union.html |title= Black Holes Inch Ahead to Violent Cosmic Union |author= Dennis Overbye |date= 7 January 2015 |publisher= New York Times |accessdate= 2015-12-29 |archive-date= 2015-10-04 |archive-url= https://web.archive.org/web/20151004181224/http://www.nytimes.com/2015/01/08/science/in-a-far-off-galaxy-2-black-holes-dance-toward-an-explosive-union.html |dead-url= no }}</ref>。該系統對於天文物理學相當重要，因為目前尚未解決超大質量黑洞合併的[[雙黑洞#最終秒差距問題|最終秒差距問題]]<ref name=Time-2015-01-07>{{cite news |url= http://time.com/3657299/black-hole-collision/ |title= Ka-Boom!
