That the Universe is largely composed of a cosmic web consisting of narrow filaments upon which galaxies and intergalactic gas and dust are concentrated has been known for more than a decade. While a ...

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

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

A massive galaxy (blue dot) warps the light emitted by an active black hole (orange dots) in a phenomenon called gravitational lensing. | Credit: NASA/ESA/CSA A beautiful, "bejeweled" halo of warped ...

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 ...

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 ...

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 ...

Across the universe: computer simulations suggest that matter in the universe is distributed in a "cosmic web" of filaments, as seen in the image above from a large-scale dark-matter simulation (the ...

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 ...

Astronomers found a quasar with the brightest radio emission ever observed in the early universe, due to it spewing out a jet of extremely fast-moving material. Scientists have revealed in ...

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 ...

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 ...
