Astroboffins spy the brightest quasar that lit the universe's dark ages

Scientists have spotted the brightest ancient quasar formed when the universe was less than billion years old, according to research published in The Astrophysical Journal. The newly discovered quasar, known by its not very catchy name PSO J352.4034-15.3373 or P352-15, also shoots out huge jets of plasma that appear extremely …

Astroboffins spy the most greedy black hole yet gobbling a Sun a day

Astronomers have spotted the greediest supermassive black hole going through the fastest growth spurt some 12 billion years ago. The humongous hole, codenamed QSO SMSS J215728.21-360215.1, is the staggering size of about 20 billion suns, and grows at a rate of 200 million suns over a million years. It has a voracious appetite …

Boffins find a new way to catch the 'tails' of quasars in massive galaxies

Physicists have managed to analyze the hidden "tails" swirling around quasars in supermassive black holes by using a combination of radio telescopes and the Gaia space observatory. A quasar is an active black hole, identified by plumes of matter shooting out from its center, and a shroud of gas and dust known as an accretion …

Boffins clock MONSTER BLACK HOLES inside quasar-hosting galaxy near Earth

Scientists have spotted two central black holes raging and skating around each other in Markarian 231 (Mrk 231) – the nearest galaxy to Earth that hosts a quasar. The binary black hole could collide in just a few 100,000 years from now, predicted astroboffins who made the discovery using NASA's Hubble Space Telescope. "We are …

Astroboffins perplexed by QUADRUPLE QUASAR CLUSTER find

Baffled astronomers at the Keck Observatory in Hawaii are scratching their heads after finding a group of four quasars, a gathering that current cosmological thinking rates as a ten million-to-one chance of occurring. quasars Four into one shouldn't go "If you discover something which, according to current scientific …

COSMIC FATTY from the DAWN of TIME simply can't exist – astroboffins

Researchers from Australia and China have turned up an unfeasibly large black hole that almost dates back to the beginning of time. At 12 billion times the Sun's mass, and in a quasar that was a million billion times as energetic as the Sun, it's not actually the largest black hole ever spotted. However, its redshift indicates …

Stanford academics unleash Quasar cluster juggler on mega bit barns

Exclusive For all their orderly aisles of flickering servers and the reassuring hum of tens of thousands of spinning drives, data centers are terrifically rowdy places. The trick is to hide the constant bar fight going on between applications and the underlying IT resources with layers and layers of software, and one of the best ways to …

Schmidt still scanning the skies 50 years after defining the quasar

Interview Fifty years ago this Friday Dutch astronomer Maarten Schmidt revolutionized his field with a paper on quasars, the energy sources that now act as terrestrial guide points in our exploration of the cosmos. His initial 1963 paper was disputed by some of the biggest names in astronomy, got him on the cover of Time magazine ( …

MONSTER QUASAR BLAST blows stunned astro boffins' WIGS OFF

Physics boffins have discovered a dying galaxy whose black hole core has emitted the biggest burst of energy ever to be found by scientists. Researchers at Virginia Tech in the US examined the record-breaking quasar, dubbed SDSS J1106+1939, using a colossal telescope in Paranal, Chile to observe what they described as a " …

BOSS Bang boffins: DARK ENERGY spreading across the Universe

New data from looking at black holes has confirmed a theory that dark energy is accelerating the expansion of the universe. The findings come from a research team that goes by the name of BOSS (Baryon Oscillation Spectroscopic Survey). Scientists have used a technique of measuring the light emitted from quasars - dying …

Astroboffins probe mysterious 'blazar'

An international team of astronomy brainboxes say they have gained valuable initial insights into the behaviour of faraway, molto weirdo space objects known as "blazars". NASA concept art of a blazar in action What a blazar would look like if it wasn't a blazar*. A blazar, according to the boffins, is like a quasar but, …

Quasar scrutineers use entire galaxy as telescope lens

A team of crafty astroboffins say they have managed to probe the guts of a quasar ten billion lightyears away - using nothing less than an entire galaxy as the main lens of their telescope.
