Astronomers have spotted the brightest quasar (shown here in artistic impression) yet discovered in the early universe. Astronomers have just discovered a galaxy with a supermassive black hole at its core, and it's located over 12.8 billion light-years away from Earth, just a billion years shy of the Big Bang. Known as a quasar, this object is the brightest of its kind ever seen in the distant universe. The discovery gives scientists a better look at the universe's early years and helps them understand how supermassive black holes form and evolve. The newfound quasar, dubbed UHS J043947.08 163415.7,
Astronomers have discovered the brightest object in the Universe and it dates back to almost the beginning of time. The fantastic luminosity of the distant quasar is equivalent to 600-trillion suns and was found using the Hubble telescope. Data was collated from NASA,the ESA and the Gemini North telescope in Hawai'i. Collectively it provides an insight into the birth of galaxies when the Universe was only a billion years old. Scientists claim it is by far the brightest quasar yet discovered in the early universe.
It's called a quasar and it's located so far away from Earth that the light being seen now was emitted shortly after the Big Bang occurred. An artist's conception shows how a very distant quasar may look close-up. This object is the brightest quasar yet discovered in the early universe. An extremely distant quasar has been discovered, one that astronomers say emits light from the dawn of time, a new study suggests. Quasars are huge, incredibly bright celestial objects located in the center of galaxies.
The universe could be expanding much faster than astronomers thought. New measurements of the Hubble Constant have revealed a discrepancy between the new number and other recent estimates, suggesting something'beyond our current knowledge' may be at play. These findings could shed new light on the little-understood behaviour of dark matter and dark energy, and could even point to holes in Einstein's theory of general relativity. The team used the Hubble Space Telescope to observe three galaxies that act as'gravitational lenses,' each bending light from a distant quasar. In the new study, the researchers estimate the Hubble Constant – the universe's rate of expansion – to be roughly 71.9 kilometers (44.7 miles) per second per megaparsec.
Often described as cosmic lighthouses, quasars are luminous beacons that can be observed at the outskirts of the Universe, providing a rich topic of study for astronomers and cosmologists. Now scientists have announced the discovery of the second-most distant quasar ever found, at more than 13 billion lightyears from Earth. UC Santa Barbara's Joe Hennawi, a professor in the Department of Physics, and former UCSB postdoctoral scholars Frederick Davies and Feige Wang, provided crucial modeling and data analysis tools that enabled this discovery. The results are currently in preprint on ArXiv and will appear in The Astrophysical Journal Letters. The researchers have named the object Po niua ʻena, which means "unseen spinning source of creation, surrounded with brilliance" in the Hawaiian language.
