First, the center of a galaxy is not a "bright light". It's a mathematical point. This is a technical quibble, and it is true that the centers of spiral galaxies (like the Milky Way) tend to be brighter than the rest of the disk due to the density of the stars there.
The reason we don't see the center of our own galaxy as a particularly bright patch is because we don't see by radio waves. In the radio spectrum, the center of the galaxy is quite bright. However, we see by visible light, and there's a lot of dust and gas between us and the center of the galaxy, which blocks out most of the wavelengths we can see.
The closest galaxy which can be seen by the "naked eye" (blushing) is the Andromeda Galaxy which is 2,400,000 light years from earth. We can't see other galaxies because of the extreme distance between Earth and the galaxies.
some flowers shrink in bright light.
If you look it up, you will see that the distance from Earth is estimated at 3300 light-years (with an error estimate of 900 light-years). This is well within our own galaxy (the Milky Way), which has a diameter of about 100,000 light-years.Pressumably, nebulae exist in other galaxies, but the more well-known nebulae are in our own galaxy, because, being closer, we can observe them best.
Yes. Well, parts of it. If you look down, on the floor, you see planet Earth, which is part of our own galaxy; and all the stars and planets you see in the night sky are part of our own galaxy. Moreover, if it's dark enough, you can see a band of light, which is what gave our galaxy the name, "Milky Way".

Since our galaxy is about 100,000 light-years side to side and we are about 30,000 light-years from the centre of our galaxy then by dividing 100,000 by 2 making it 50,000 and then minus 30,000 then it estimates we should be 20,000 light-years from the nearest edge of our galaxy.
Our sun is about 25,000 light years from the centre of the milky way.. It's about half way out from the centre of our galaxy.. So our galaxy from end to end would be 100,000 light years across..
The Galactic centre is about 27,000 light years from us.
The Blackeye Galaxy (M64 galaxy).
The Cigar Galaxy (M82 galaxy).
Yes, the Andromeda galaxy is visible from Earth with the naked eye under ideal conditions. It is the closest spiral galaxy to our Milky Way and can be seen in the night sky from the Northern Hemisphere.
About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.
In skys where there is little or no light pollution, the cisble arms of our galaxy, the "Milkyway" are very prominent and bright. Ancient mythologies sometimes suggested that this background band of light was the 'milk' from which the gods churned the Earth. Hence our galaxy is known as the Milkyway.
To be factually correct, there isn't any light at the centre of the Milky Way Galaxy as it's a super massive black hole - and no light escapes. We cannot observe this area of the Galaxy in the visible spectrum because of all the galactic dust in the way.
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
Bode's Galaxy (M81 galaxy) and the Cigar Galaxy (M82 galaxy).
The distance between Earth and the Seyfert galaxy can vary depending on which specific galaxy you are referring to. On average, Seyfert galaxies are located around 40 million light-years away from Earth.
