What do astronomers use to study quasars?
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
What are the properties of a quasar?
Quasars are the most radiant objects in space. They contain a central black hole surrounded by a disk of gas and dust. They emit large amounts of radio waves but not much visible light.
Why do scientists think that quasars emit a large amount of energy?
Scientists think that quasars emit a large amount of energy because they believe each quasar has an incredibly large black hole in the center of it. They believe a torus, or disk of dust and gas, has material that falls near the black hole causing it to hear to millions of degrees that accelerates the reaction outward.
Do quasers emit large amounts of radio waves?
yes
Do quasars emit gamma rays?
yeah, that and radio waves
What is a massive collection of gasses in space that emit large amounts of energy?
A star is a massive collection of gas in space, that emits large amounts of energy.
Do Quasers emit light?
Yes, quasars are the most luminous objects in the universe.
Is the one thing all volcanic eruptions have in common is that they emit large amounts of gas?
Yes
What emits extremely large quantities of energy?
Quasars emit more energy than anything else in the universe. Quasars are massive black holes at the cores of some galaxies, swallowing matter and stars and ejecting them out collimated bipolar jets of matter and radiation which stretch out hundreds of thousands of light years. Since there are quasars in galaxies close by, these indicate the evolution of our universe.
Do all quasars have host galaxies in them?
Quasars do not have galaxies in them, quasars are at the hearts of galaxies. All quasars are located in galaxies, as a quasar involves massive amounts of material falling into a supermassiv black hole. Neither of these can be found outside of a galaxy.
Why isn't a quasar a planet?
Quasars are not planets because they are not spherical and do not orbit a star. A quasar is a supermassive black hole in the process of consuming large amounts of matter.
Emission nebulae like M42 occur only near stars that emit large amounts of?
ultraviolet radiation
