At the time of the news, the scientists don't know why yet. Researching trying to find the missing mass of our galaxy believe they might have found the missing mass. The equivalent of a white hole in a quasar would be the stream. Watch this video and learn all about Quasar Vs. (galaxy) A highly variable active galaxy, characterized by a very compact and highly variable energy source (a supermassive black hole) at the center and its strong optical polarization and variability. The reason why they are believed to be in orbit round one another is the result of two galaxies colliding.

The furthest thing we can see with our naked eye is the Andromeda Galaxy which is a mere 2.4 million light years away. If the stream is angled slightly towards us, then its a Quasar and if the stream is angle directly towards us, its a Blazar. You can decline to give a name which if that is the case, the comment will be attributed to a random star. Ref: Starchild, As Quasars are so far away, their light has been travelling for billions of years.

The discovery of the distinct infrared colors of blazars opens a new diagnostic tool in the study of these extreme galaxy nuclei.Quasar vs blazar 23 m). A future paper will consider the physical mechanism(s) producing the infrared, X-ray, and gamma ray emission. It turns out that the infrared colors of this extreme group are even more distinctly identified, and the team discovered a quantitative relationship between the infrared and gamma ray colors. In a second paper, the astronomers take advantage of this new method to examine the subset of blazars that are gamma ray emitters. The scientists find an infrared source within the position uncertainty whose distinct colors mark it as a blazar, and conclude that the extreme source is probably a blazar located at the position of the infrared source. Using this new identification method, the team examines one known, extreme gamma ray source whose character had been mysterious in part because the gamma ray detection could not pinpoint the precise position of the source on the sky.

In a blazar, however, a completely different mechanism is apparently at work: the ejected beam of charged particles, moving in a powerful magnetic field at nearly the speed of light, radiates infrared light of a distinctly different color than dust emission. In most galaxies the infrared radiation comes from dust, heated either by star formation or ultraviolet radiation from the vicinity of the massive black hole. Ninety-seven percent of known blazars were easily picked out from thousands of other WISE sources because their colors in the infrared are different from the colors of other kinds of galaxies. In a new paper in The Astrophysical Journal, the team report their discovery that the infrared bands are remarkably effective at finding blazars. The astronomers matched galaxies known to be blazars with objects measured by WISE in regions of the sky where the data have been reduced and made public. The recently launched NASA Wide Infrared Survey Explorer (WISE) satellite has just completed an infrared survey of the whole sky in four infrared colors. Although relatively few, their powerful emissions make them major contributors to the overall picture of the cosmos.ĬfA astronomers Francesco Massaro, Raffaele D'Abrusco, Josh Grindlay, and Howard Smith, and a colleague, have come up with a new method to find and study blazars. But blazars are among the rarest of active nuclei, with only about 2700 known, and the physical processes that trigger and sustain such jets are still not known. The intense X-ray and gamma ray emission we see, and the variability as well, are thought to be the results of our fortuitously staring right down the throats of such cosmic monsters. Astronomers suspect that this bizarre behavior results when matter falling onto the vicinity of the massive black hole erupts into powerful, narrow beams of high velocity charged particles.
