Quasars are the brightest objects in the universe, so bright they can be seen from across the universe. Observations continue to show that most quasars are surrounded by a relatively faint nebulous patch. Astronomers are trying to identify the nature of these patches. The above false-color picture shows a central quasar embedded in an unusual elliptical galaxy. The galaxy is being gravitationally distorted by a neighboring galaxy. Recent evidence indicates that most quasars live near the centers of large, elliptical galaxies - even those quasars where no host galaxy could be found before. Quasars themselves are thought to result from matter falling toward supermassive black-holes.
