It is moving away from the observed point at a great speed.
Yes.
The increasing distance between the two galaxies will red shift light traveling between them in either direction.
A substantial redshift is usually observed in other galaxies (not in our Milky Way), when they are far away and move away from us quickly.
They would see an equal redshift.
That is called "redshift".
True
It is called simply a "globular cluster". Another possibility: The closely allied stars at the center of a galaxy tend to be older, redder stars than those in the outlying arms of the galaxy.
More massive stars usually appear brighter, therefore bluer. Less massive being redder, and yellow in the middle. I could be wrong.
The hotter they are, the bluer they are, the cooler they are, the redder they are.
Each color has a wavelength and frequency associated with it. We're familiar with the colors of the rainbow: red, orange, yellow, green, blue and violet. These colors range from longer wavelength (lower frequency) red up through shorter wavelength (higher frequency) violet. As one moves up through those colors from red to violet, the color is an indication to relative wavelength.
It varies. The redder it is it costs more. Retail prices is $3-$50.
Actually, it doesn't matter what kind of galaxy it is, because it depends on what kind of stars are in it. If a galaxy has a lot of red giants, it will appear redder than a galaxy with mostly blue-white stars. Older galaxies might be redder than younger galaxies due to the fact that older stars appear redder.

redder, reddest
They appear redder because they have picked up oxygen at the lungs.
redder, reddest
Light had properties of frequency that related to colour. It is apparently contract in the direction moving toward the observer (higher frequency-short wavelength) and apparently elongated in the direction moving away from observer (lower frequency-high wavelength). What moving toward us is tend to be look more blue than usual (blue shift) and what away from us is redder than usual (red shift).
Theodor Redder was born on 1941-11-19.
'Redder in nood' is Dutch. It means 'lifesaver'.
Yes, as in "After being in the sun, his skin was redder than before."
"The proof of it will turn to redder drops." The palindrome is, of course, "redder".
