Galaxies may be aligned across 1 billion light-years
An astrophysicist at the University of Liège in Belgium, and his team used the very large telescope in northern Chile in order to measure the orientations of 19 quasars, blazing disks of gas that twirl around supermassive black holes in the centers of galaxy. Each of them lives in one of four orientations of four groups that are about 13 billion light-years away and centered on the constellation Leo. Powerful jets of charged partices spew from the quasars point in almost the same direction.
“The conclusions are on shaky ground”, says Mike DiPompeo, an astrophysicist at the University of Wyoming. “It would be surprising”, he says, “if quasars knew how their neighbors were aligned.”
