A quasar is a highly energetic celestial object, and it exists at the perimeter of the visible universe. That is, they are the furthest known things from Earth. Due to the nature of the universe, they are also the most ancient known things. Scientists believe that quasars are the active nuclei of young galaxies, and are powered by supermassive black holes.

A quasar (contraction of QUASi-stellAR radio source) is an astronomical source of electromagnetic energy, including radio waves and visible light. As of 2007, the scientific consensus is that these objects are extremely far away (explaining their high redshift), extremely luminous (explaining why they can be seen despite being so far away), and very compact (explaining why they can rapidly change brightness). They are thought to be the active nuclei of young galaxies.
