Quasars, or QUASi-stellAR objects, are found at the edge of the observable Universe. Discovered in 1963, they emit prodigious amounts of energy to be visible across billions of light-years. Many astronomers believe a giant black hole, fueled by infalling gas, dust, and stars, powers their central engine. This Hubble Space Telescope gallery offers a look at these distant objects.
