    Many quasars also produce relativistic jets, which are powerful streams of charged particles ejected at nearly the speed of light. These jets can extend thousands of light-years into space and contribute significantly to a quasar’s luminosity. The interaction of these jets with surrounding matter leads to additional radiation production.

    3. Redshift and Distance

    Quasars are located at considerable distances, and their light is redshifted due to the expansion of the universe. This characteristic allows astronomers to study the history of the universe and the development of black holes over billions of years.
