A team of American astronomers led by Paul Green searched for possible merger events4 by looking through a sample of binary quasar candidates in the Sloan Digital Sky Survey Data Release 6. They found two quasars, SDSS J125455.09+084653.9 and SDSS J125454.87+084652.1, inside a large highly disturbed galaxy. On the sky, the two quasars are separated from one another by just 21 kiloparsecs (68,000 light-years). For comparison, the visible diameter of the Milky Way Galaxy is 37 kiloparsecs (120,000 light-years). 041b061a72
