Scientists have discovered the energetic core of a distant galaxy that shatters the record for the brightest object in the early universe, blazing with the light equivalent to trillion suns. The quasar is Researchers announced its discovery on Jan. Several powerful ground-based telescopes and the Hubble Space Telescope pooled their observations of the object, now designated J The quasar gets its brightness from a supermassive black hole:
The brightest celestial object in the early universe has been spotted
The brightest object in the universe was just discovered, but is it still there? – BGR
As gas in the disk falls towards the black hole, energy is released in the form of electromagnetic radiation , which can be observed across the electromagnetic spectrum. The power radiated by quasars is enormous: The term quasar originated as a contraction of quasi-stellar [star-like] radio source , because quasars were first identified during the s as sources of radio-wave emission of unknown physical origin, and when identified in photographic images at visible wavelengths they resembled faint star-like points of light. High-resolution images of quasars, particularly from the Hubble Space Telescope , have demonstrated that quasars occur in the centers of galaxies, and that some host-galaxies are strongly interacting or merging galaxies. Quasars are found over a very broad range of distances, and quasar discovery surveys have demonstrated that quasar activity was more common in the distant past.
Scientists find the brightest object in the universe from the dawn of time
Quasars are distant galaxies with supermassive black holes active in their cores. Instead of swallowing matter into its swirling black mass, about 10 percent of quasars shoot radio emissions almost as fast as the speed of light into space. The quasar, called PSO J Faraway quasars have been discovered before, and even brighter ones have been observed, but none have been both so distant and so bright, according to Zoltan Haiman, a professor of astronomy at Columbia University in New York City, who was not involved with the new research.
Three main components of the object are seen, with two of them showing further substructure. The brightest object in the universe has been discovered, a quasar from when the universe was just 7 percent of its current age. The quasar, now known as PSO J
