Hubble astronomers have looked at one of the most distant and brightest quasars in the universe and are surprised by what they did not see. quasar: an astronomical object of very high luminosity found in the centres Photo AURA/STScI/ NASA /JPL (NASA photo # STScI-PRCa). I just checked the site townsms.de townsms.de which is still up, unfortunately. Let me.

It took years of study to realize that these distant specks, which seemed to indicate stars, are created by particles accelerated at velocities approaching the speed of light. It also is the smallest unit of matter that has the characteristic properties of a chemical element In other words, the wavelength of each line was 1. Individual quasars appear as their central black holes begin to accrete gas at a high rate, possibly triggered by a merger with another galaxy, building up the mass of the central black hole. Since their discovery in the early s, quasars, or quasi-stellar radio sources, continue to baffle astronomers. Phil Newman If you have comments or questions about the StarChild site, please send them to us. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy. Although light cannot escape from the black hole itself, some signals can break free around its edges. Articles from Britannica encyclopedias for elementary and high school students. They are up to a thousand times as bright as the average galaxy. Quasars emit energies of millions, billions, or even trillions of electron volts. Help us was ist eine psc this article!

In other words, the wavelength of each line was 1. To get the best experience possible, please download a compatible browser. The term quasar derives from how these objects were originally discovered in the earliest radio surveys of the sky in the s. The quasar dates back to less than one billion years after the big bang. At some point, quasar activity ceases completely, leaving behind the dormant massive black holes found in most massive galaxies. Keep Exploring Britannica light. The word quasar is short for "quasi-stellar radio source". WFPC2 was installed on Hubble during shuttle mission STS
