A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole. Source: https://earthsky.org/astronomy-essentials/definition-what-is-a-quasar…

Quantum shuttle to quantum processor made in Germany launched
The quantum computer race is in full swing. Germany has long been one of the world leaders in basic research. An alliance between Forschungszentrum Jülich and the semiconductor manufacturer Infinion, together with institutes of the Fraunhofer-Gesellschaft (IAF, IPMS) as well as the Leibniz Association (IHP, IKZ), the universities of Regensburg and Konstanz and the quantum start-up HQS, now aims to apply…
Maarten Schmidt solves the puzzle of quasars
On February 5, 1963, Maarten Schmidt unraveled the mystery of quasars and pushed back the edges of the known cosmos. His insight into quasars – the most distant and luminous objects known – has changed the way scientists view the universe.

What do redshifts tell astronomers?
A redshift reveals how an object is moving in space and enables astronomers to discover otherwise-invisible planets and the movements of galaxies, and to uncover the beginnings of our universe. Source: https://earthsky.org/astronomy-essentials/what-is-a-redshift…
Researchers discover the earliest supermassive black hole and quasar in the universe
Nearly every galaxy hosts a monster at its center—a supermassive black hole millions to billions times the size of the Sun. While there’s still much to learn about these objects, many scientists believe they are crucial to the formation and structure of galaxies. What’s more, some of these black holes are particularly active, whipping up stars, dust and gas into glowing…
A new record for the most distant quasar
Astronomers have a new measurement for the distance of quasar J0313-1806, making it the new record-holder for the most distant quasar known. We’re seeing it just 670 million years after the Big Bang, or more than 13 billion light-years away. Source: https://earthsky.org/space/new-record-most-distant-quasar-black-hole-j0313-1806…
Study investigates emission from a distant red quasar
Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, an international team of astronomers has performed observations of HSC J120505.09−000027.9—the most distant red quasar so far detected and found that it showcases an extended emission of ionized carbon. The finding is reported in a paper published January 4 on arXiv.org. Source: https://phys.org/news/2021-01-emission-distant-red-quasar.html…
Most distant quasar may help us solve how enormous black holes form
Astronomers spotted a quasar containing a supermassive black hole about 13 million light years away, which may shed light on how these colossal black holes form Source: https://www.newscientist.com/article/2264663-most-distant-quasar-may-help-us-solve-how-enormous-black-holes-form/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Most distant quasar discovered sheds light on how black holes grow
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 years after the Big Bang, when the universe was only 5% its current age, the quasar hosts a supermassive black hole equivalent to the combined mass of 1.6 billion suns….
Galaxy survives black hole’s feast—for now
Black holes are thought to gobble up so much surrounding material that they put an end to the life of their host galaxy. In that process they create a highly energetic object called a quasar which was previously thought to halt star birth. Now researchers have found a galaxy that is surviving the ravenous forces of a quasar by continuing to…
