What is the very bright core of a distant galaxy moving away from Earth?

Question

please answer it. =]

Answer 1

Which Galaxy? Several nearby galaxies have bright cores, and all of the distant galaxies are moving away from us (expansion of space).

Answer 2

All the galaxies (except those in the Local Group) are moving away from the Milky Way galaxy (which we are part of).

The very bright cores of galaxies have a couple of terms, depending on the intensity of the rdiation detected and a few other variables.
Quasar - a bright galactic nucleus that is so far away that we can't detect the home galaxy
AGN (active galactic nucleus) - bright, active galactic cores that outshine their host galaxies, usually with radio jets moving at close to the speed of light along the rotation axis and in many cases starburst activity (intense star formation activity).
Blazar - fairly new term for AGNs where the jets point towards the earth
In all 3 cases, the current theory is that they are all powered by supermassive black holes at their centres.
One fairly nearby blazar galaxy is M87 in the Virgo Cluster.
Hope this answers it. =]

Answer 3

properly, Parallax is like this: enable's say the gas tank on your vehicle is precisely 0.5 complete, and it has a needle gauge, no longer a digital one.there's a needle that is in the front of a graduated scale of a few form, and the needle is pointing quickly up. in case you seem on the needle, from the driver'S seat, you'll discover that that needle factors to the 0.5 way mark on the size. If besides the indisputable fact that, you're sitting interior the PASSENGER'S seat, and also you seem over, you'll see a unique result. In NZ (because you're sitting on the left as a passenger), you may imagine the tank examine slightly extra complete than that is, because you observe the needle pointing quickly up, besides the indisputable fact that the size in the back of evidently shifted slightly suitable. That shift is termed Parallax. that is the version in visual charm of an same ingredient from 2 different commentary factors. to attempt this with stars, you imagine of the celeb you're concentrated on because the needle, and some thing of the celebrities you'll discover because the size, then you really seem on the celeb from an same position in the international, yet six months aside, utilising the Earth's orbit around the sunlight as to create your driver's seat and your passenger's seat. Dig it? we may also tell how a concepts away some stars are by technique of utilising their absolute value, and evaluating it to their obtrusive value. it truly is an complete different procedure. that's ideal to target to apply both at the same time as achieveable, besides the indisputable fact that the reality is, that the farther away a celebrity is, the extra sturdy and extra misguided that's to apply the parallax approach.

Answer 4

It is generally believed that at the core of every galaxy ther is a Super Massive Blackhole. The brightness comes from the large concentration of stars orbiting close to the galactic center.

Answer 5

do you mean a quasar? they are the very bright cores of distant galaxies that are moving away from us. or a seyfert galaxy, which is kind of a brighter quasar.

Answer 6

A Quasar.
