For a quasar with an apparent size on a monthly scale, its maximum size would be several times that of our solar system, but far smaller than a galaxy. So far, all observed quasars have been found in this range, so all quasars will have maximum sizes of roughly that of the solar system or larger.Jan 30, 2562 BE
Can a quasar destroy a galaxy?
New data from NASA's Hubble Space Telescope details what may be the most powerful phenomena in the universe: the “quasar tsunami,” a cosmic storm of such terrifying proportions that it can tear apart an entire galaxy.
Are quasars bigger than the Milky Way?
From a distance of about 33 light-years, this object would shine in the sky about as brightly as our Sun. This quasar's luminosity is, therefore, about 4 trillion (4×1012) times that of the Sun, or about 100 times that of the total light of giant galaxies like the Milky Way.
Is a quasar a galaxy?
Quasars got that name because they looked starlike when astronomers first began to notice them in the late 1950s and early 60s. But quasars aren't stars. Scientists now know they are young galaxies, located at vast distances from us, with their numbers increasing towards the edge of the visible universe.
How are quasars different from galaxies?
Almost all galaxies, including our own, are thought to contain supermassive black holes in their centers. Quasars represent extreme cases where large quantities of gas are pouring into the black hole so rapidly that the energy output is a thousand times greater than the galaxy itself.
Can a quasar destroy Earth?
The illumination from a quasar, along with all the radiation it throws off, would mess with Earth's atmosphere. The light is enough to energize particles that make up the atmosphere and frees them from Earth's gravity. And we really need our gravity. Without it, Our atmosphere would be destroyed.
What is a quasar tsunami?
Astronomers have observed "quasar tsunamis," gigantic waves of radiation that emanate from quasars, which have the destructive power to wreak havoc on the formation of galaxies.
What would happen if a quasar hit Earth?
The illumination from a quasar, along with all the radiation it throws off, would mess with Earth's atmosphere. The light is enough to energize particles that make up the atmosphere and frees them from Earth's gravity. And we really need our gravity. Without it, Our atmosphere would be destroyed.
How big is a quasar galaxy?
While they vary in size, the most common size is most commonly around 5 on this graph, which equates to 100,000 AU, or about 1.5 light years across. That might seem pretty big, but remember that these objects are brighter than our galaxy (consisting of 200 billion stars).
Was the Milky Way a quasar?
If such a jet at the center of a distant galaxy points towards Earth we may see it as quasar. Hence the answer is most likely yes, the Milky Way or some of its predecessor galaxies will probably have had quasars at their centers, at some period when consuming lot of material, and seen from appropriate direction.
