The quasar is the deadliest object in the universe. It is able to destroy not only a planet or a star, but also the whole galaxy. For example, even such a galaxy as our milky way. They quasars destroy everything that comes their way. In the center of the quasar there is a massive black hole that sucks objects into itself, destroys them without a trace. The energy produced by the quasar in one second exceeds 10 trillion times the energy of the Sun.
The name quasar-means “star-shaped radio source”, although at the moment it is found that many quasars are not so active in the radio range. In the optical range, most of the quasars resemble stars, despite this their radiation is observed in other spectral ranges, sometimes even not only in the optical. In quasars located at a short distance in the optical range is difficult to detect some structure, and in the radio band almost all quasars have a fairly well-developed structure, which goes far beyond the optical image.
