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 ...

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 ...

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 ...

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

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 ...

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 ...

Astronomers believe our universe is home to at least 100 billion galaxies. And just like us, each of those massive collections of stars and other space stuff will eventually die. But also like us, ...

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 ...
