Hubble telescope finds rare double quasars in ancient galactic collisions

NASA’s Hubble Space Telescope has captured not one but two pairs of distant quasars that existed some 10 billion years ago, a new study reports. 

According to the team leading the research, the discovery was like finding a needle in a haystack, as the chance of locating a double quasar compared to a single quasar is just one in 1,000.
