Quasars also provide some clues as to the end of the Big Bang 's reionization. For convenience, the abbreviated form 'quasar' will be used throughout this paper. Quasars can be detected over the entire observable electromagnetic spectrum including radio , infrared , visible light , ultraviolet , X-ray and even gamma rays. In the s, unified models were developed in which quasars were classified as a particular kind of active galaxy, and a consensus emerged that in many cases it is simply the viewing angle that distinguishes them from other classes, such as blazars and radio galaxies. This page was last edited on 19 October , at It appears to be an extremely distant star putting out huge amounts of energy. Believed to be the oldest and most distant objects ever detected, quasars are billions of light-years from Earth and moving away from us at nearly 80 percent of the speed of light. Quasare wurden inzwischen bis zu einer Rotverschiebung von 7,1 entdeckt. In a universe containing hundreds of billions of galaxies, most of which had active nuclei billions of years ago but only seen today, it is statistically certain that thousands of energy jets should be pointed toward the Earth, some more directly than others. You Won't Feel a Thing". So when we look at quasars, we're observing these objects as they were billions of years ago, and we're able to see part of the early history of the universe.
