Quasi-stellar radio sources (quasars) are the most distant cosmic objects observed by astronomers. Although not visible to the naked eye, quasars are also among the most energetic of cosmic phenomena. Even though some quasars may be physically smaller...
At the beginning of the twenty-first century, quasi-stellar radio sources (quasars) were the most distant cosmic objects observed by astronomers. Although not visible to the naked eye, quasars were also among the most energetic of cosmic phenomena....
Among the most unusual objects in the universe, quasars (quasi-stellar radio sources) are strong radio sources with unusual properties. In the early 1960s, a number of powerful radio sources were pinpointed in space which did not correspond with the...
The term quasar is used to describe quasi-stellar radio sources that are the most distant, energetic objects ever observed. Quasars are enigmatic. Despite their great distance from Earth, some are actually brighter than hundreds of galaxies combined,...
A quasar (contraction of QUASi-stellAR radio source) is an extremely bright and distant active galactic nucleus. They were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light that were...
Early morning. Coffee simmering. Downstairs the furnace squeaks and rumbles to life, like the tuning-up of a distant orchestra. I settle in an easy chair to read three news stories about the beginning of the world. On the stereo, Joseph Haydn's "Creation" oratorio. ...
The birth of twin quasars Astronomers have resolved a distant, fuzzy patch of light designated PHL 1222 into two separate objects that may represent a pair of quassars less than 100,000 light-years apart. Quasars, thought to be the active cores of certain...
Astronomers have taken a baby step in trying to answer the cosmic question of where we come from.Planets and much on them, including humans, come from dust _ mostly from dying stars. But where did the dust that helped form those early stars come from?A...
As it slowly moves in the shallow water along a beach, the robot splashes its fins like a small child playing in the surf. But the prototype device has a serious mission: destroying mines that could kill Marines and Navy SEALs as they come on...
