Why are distant stars redder than nearby stars of the same spectral type?

The reddest stars are the stars that are considered the coolest. Blue light is more effectively scattered than Red light. This is called ``interstellar reddening".

How the presence of certain element is confirmed in distant stars?
spectral analysis of light of stars help us
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
When astronomers look for evidence of hydrogen gas in the spectra of the Sun the planets and nearby stars the positions of the spectral features or lines due to hydrogen are different or the same?
They are the same.
How do we find out the composition of stars?
Spectral analysis.

Why are there no massive O and B stars?
There are stars with spectral classes of O & B (e.g. Rigel) R136a1 is a star of the spectral class WN5h. Wolf Rayet stars have this kind of spectral type.
What color stars have the lowest temp?
Typically the bigger and redder stars are the hottest.
Is spectral type k hotter then spectral type a?
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.

They are the same.
When was Distant Stars created?
Distant Stars was created in 1981.
How many pages does Distant Stars have?
Distant Stars has 352 pages.
Why are elliptical galaxies redder than disk galaxies?
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.
What is the least luminous spectral class?
Spectral class Y, which is typical of "brown dwarf" stars.
How do we find out the composition of stars?
Spectral analysis.
