Quasars at the edge of the universe
Description:
Well, the universe does not have “edges” per se but its immensity is difficult to grasp. Quasars are enigmatic objects with the highest luminous power in the universe. As such, they are also the most distant objects that can be detected. Briefly, a quasar (quasi-stellar-object) is a compact region surrounding a supermassive black hole at the center of a massive galaxy.
The photo I took here with my 14-inch telescope reveals quasars at an incredible distance of over 10 billion light-years while the “edge” of the observable Universe is 13.7 billion light-years away.
