Confirming a non-universal X-ray-to-ultraviolet relation with cosmic time is quite surprising and challenges our ...

A newfound quasar is blasting out the brightest radio emissions ever observed in the early universe, new research reports. Quasars, the brightest objects in the cosmos, are comprised of giant black ...

APM 08279-5255 is a massive black hole (quasar) that contains about 140 trillion times the amount in all of Earth’s oceans ...

A team of astronomers led by the University of Arizona has observed a luminous quasar 13.03 billion light-years from Earth - the most distant quasar discovered to date. Dating back to 670 million ...

Quasars are active black holes -- primarily from the early universe. Using a special method where you observe light that has been bent by gravity on its way through the universe, a group of physics ...

In an astonishing discovery, astronomers have identified an immense water reservoir orbiting a quasar more than 12 billion light-years away. This groundbreaking finding offers an unprecedented look ...

CHAMPAIGN, Ill. — Quasars are some of the most luminous and distant objects in the universe – and appear to have something in common with ordinary light bulbs, say researchers at the University of ...

Phil Rhodes takes a look at the Quasar Science Rainbow 2 tube light. We think he likes it. Whenever we’ve discussed full colour mixing lights in the past, we’ve always had to make excuses about our ...

One theory of a newly discovered type of black-hole quasar suggests gas flows into a central black hole. More frequent particle collisions close to the black hole make the gas hot in regions that are ...

The Quasar 360 patented unique latch and slide assembly comes in at only 16 lbs. and is the brightest, lightest and strongest on the market at the 300 Watt classification. It’s one push to rapidly ...

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 ...
