Quasars, Mysteries of the Universe

What are Quasars? Let’s take a look at the Universe Since the creation of physics and mathematics, human beings have always sought ways to understand

This is an illustration of a distant galaxy with an active quasar at its center. A quasar emits exceptionally large amounts of energy generated by a supermassive black hole fueled by infalling matter. Using the unique capabilities of the Hubble Space Telescope, astronomers have discovered that blistering radiation pressure from the vicinity of the black hole pushes material away from the galaxy's center at a fraction of the speed of light. The "quasar winds" are propelling hundreds of solar masses of material each year. This affects the entire galaxy as the material snowplows into surrounding gas and dust. Credits: NASA, ESA and J.
