Answer 1

a black hole that stars and gasses are swirling around

they''re not exactly falling in, but they are all grouped up around that area making it really really bright.

every galaxy has at least one black hole in the center

Answer 2

The others are correct, who said it is due to a relative concentration of stars toward the center. (Billions, in the case of the galaxies you showed, much more than millions.)

I would add that essentially ALL the light you see from those galaxies, and any others you find pictures of, is from stars. The many stars that can be individually resolved and that fill the view, are in our galaxy. The stars in that other galaxy are so far away that the three hundred billion or so, of them, appear to be only a glow. Lindajune said the energy emitted from a galactic black hole at the center may account for some of the light, but I would suspect very little.

All of that glowing you see in both of those images is a sea of unresolved stars. Both of them happen to be huge galaxies, similar to our own. Boggles the mind, doesn't it?

Answer 3

The light comes from millions of stars all packed into a small area of the galaxy. Also, most galaxies have a supermassive black hole at the centre, and a lot of the light we see is from material heating up to extreme temperatures as it spirals into the hole's gravity field (that heat causes the material to glow like anything else that is very hot).

Answer 4

It's just the glow from the stars. There's a much greater concentration of stars in the center of most galaxies, especially spiral or elliptical galaxies. At the very center of each galaxy is a massive black hole, but those emit no light.

Answer 5

the staggering gentle interior the centre of our galaxy is billions of stars and various hydrogen gas, which glows from the radiation from all those stars. it quite is like a extensive city centre with its city lights throughout the time of a foggy night. the reason it does not look very staggering to us is by way of the fact it is so some distance away, lots greater desirable far off from us than the solar. gentle gets dimmer with distance.

Answer 6

It's a concentration of stars, and is called the nucleus. Inside the nucleus of many (maybe all) galaxies is a black hole, so the bright light must be a concentration of stars around that feature.

Answer 7

there isnt a brightest light in the center its a black hole in the center of mainly all of the galaxies its a vortex (black hole)
in black holes there is no light and what ever goes in tha has a lot of light.like the light vanishes i thin air.
oh and a black hole can suck in another black hole depending on its mass and density

Answer 8

it comes from millions of stars near the center of a galaxies black hole. and also from the black hole itself as some light curves around it.

Answer 9

No one knows as yet, people only speculate as to what it can be. Most people believe it to be a supermassive black hole, some say its a super star or just a large mass of stars together. The central black hole is not like the other black holes in that people don't believe it was caused by a collapsed star.
