Using the Multi Unit Spectroscopic Explorer (MUSE) instrument astronomers have discovered an extended and broad Lyman-alpha emission in the form of a nebula around the quasar J1605-0112. The finding is reported February 9 in a paper published on the arXiv pre-print repository.
An astrophysicist, he joined six colleagues in suggesting that the universe is expanding sideways, and not evenly, challenging conventional theories.

A new study, published February 2 in The Astrophysical Journal Letters, gives the first evidence that more than a trillion exoplanets could exist beyond the Milky Way. Using information from NASA's Chandra X-ray Observatory and a planet detection technique called...
Strange fluctuations in the light spectra emitted from near a quasar could be due to the effect of around 2000 planets flung out of their solar systems
Since their discovery in 1963, astronomical objects called quasars have been among our most powerful probes of the early Universe. Initially seen as mysterious sources of extreme luminosity, quasars are now known to be supermassive black holes that are voraciously...
The Extended Baryon Oscillation Spectroscopic Survey (eBOSS), the world's largest galaxy survey, is part of Phase IV of the Sloan Digital Sky Survey (SDSS), a major multi-spectral imaging and spectroscopic redshift survey.
(Chinese Academy of Sciences Headquarters) The eBOSS team released its latest results on Jan. 10, 2018: a measurement of redshift space distortions (RSD) with high significance has been successfully accomplished using observations of quasars distributed 6.8 to 10.5 billion light years away from Earth (with redshifts 0.8 to 2.2).

Astronomers have discovered the most distant quasar known, which is so far from us that its light has taken more than 13 billion years to reach us. We see this quasar as it was a mere 690 million years after...
This discovery should speak for itself. Scientists have discovered a crazy example of a crazy thing at a crazy distance. We're talking about the furthest quasar yet - the incredibly bright light from a supermassive black hole 800 million times the mass of the Sun, from just 690 million years after the Big Bang. More »
Astronomers have used ESA's Herschel Space Observatory to solve a decades-old mystery about the origin of powerful cool gas winds in the hot environs of quasars. The evidence linking these powerful winds to star formation in the quasar host galaxies may also help resolve the mystery of why the size of galaxies in the Universe appears to be capped.
Thanks to the beacon-like glare of a quasar, astronomers have discovered the most distant supermassive black hole they’ve ever seen, carrying the mass of a whopping 800 million suns. The quasar J1342+0928, described in the journal Nature, sheds new light on a mysterious epoch near the dawn of the...
(Massachusetts Institute of Technology) A team of astronomers has detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar and presents a puzzle as to how such a huge object could have grown so quickly.
(Carnegie Institution for Science) A team of astronomers led by Carnegie's Eduardo Bañados used Carnegie's Magellan telescopes to discover the most-distant supermassive black hole ever observed. It resides in a luminous quasar and its light reaches us from when the universe was only 5 percent of its current age -- just 690 million years after the Big Bang.
(Association of Universities for Research in Astronomy (AURA)) To understand when supermassive black holes first appeared, astronomers scan the skies for actively-feeding black holes (known as 'quasars') from the Universe's distant past. Show More Summary
A quasar from the early universe could help us understand how the biggest black holes form and when the universe had its last major transformation
The incredible discovery is helping scientists define our understanding of how black holes grow.
