What color is the light from stars when they are moving away from us?

The centre of a galaxy is composed of many different types of stars, these can be yellow, blue, orange etc. The centre of a galaxy usually also contains interstellar dust. looking at galaxies from afar, all these factors give the centre of a galaxy a white color in the visible spectrum, as white light is a mixture if all the colors.

What you get when stars are moving away?
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
What does it mean when the color of an object in the universe shifts toward red?
It is the color of the light shift. either red or blue, from an object, not the object itself, that determines if it is moving away( RED) from us or moving toward us (BLUE).
What light has the same causes as the pitch of sound?
Stars in the universe are all moving away from us, so their wavelength will be red shifted. When the source of a sound is moving away from us, the wavelength of the sound will increase, i.e. the frequency will lower. In both cases, this is known as Doppler shift.
Why do you see stars twinkling but planets do not?
the stars emitt its own light. But the planets do not have any own light. It absorbs the light from the stars like a sun. It just reflects the light. And also the stars are far away from the earth than the planets. So we can found the twinkling of stars but not the planets.
What can astronomers learn about the stars motion based on wavelength shifts?
They can determine how fast the star is moving toward or away from us. The chemical spectral signature is used to determine the Doppler shift of the visible light reaching us. This is then used to calculate how fast we and the star in question are moving toward or away from each other.
What you get when stars are moving away?

How does the color of stars from earth differ from their actual color?
Since the stars are not stationary in relation to earth, i.e. they are moving towards or away from the Earth, their light will be subject to Redshift (if they are moving away) or Blueshift (if they are getting closer). The faster they are changing distance, the greater the shift in wavelength.
Why do stars take so long to change?
The stars are light years away which is the distance light travels in a year. A light year is about 3x108km. The farther something is from you the slower they seem to travel so the stars don't look like the are moving. In reality, they are moving very fast.
What are shifts in the wavelengths of light of stars either approaching or moving away from earth called?
The Doppler effect.
What happen if a light move closer to the object?
The redshift that scientists speak of in stars, indicating that they are moving away, is complemented by a shift toward the blue in the spectrum by light moving toward a viewer.
How do you know stars are moving towards or away?
you don't, we ar ethe ones moving not the stars.
Since light from distant stars have not reach us will the sky get brighter with time?
No. The vast majority of stars are so far away that even though their light is reaching us, they cannot be seen without a telescope. Additionally, the farthest stars from Earth are moving away from us so fast that their light is redshifted beyond the visible spectrum.
Are the stars moving away?
not all of them only the red ones
What shift of color do you receive from stars as you get closer?
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
What does it mean when the color of an object in the universe shifts toward red?
It is the color of the light shift. either red or blue, from an object, not the object itself, that determines if it is moving away( RED) from us or moving toward us (BLUE).
What is a star call when it is moving away from the earth?
A star moving away from the earth is still called a star, but the color of the light that we see will be "redder" than it actually is. This is called redshift, and a link can be found below for more information.
Stars moving away from the earth show a red shift Why?
The star is moving away from us. Therefore, the Doppler effect must be considered. The Doppler effect is waves (in this case light) will be compressed in front of a moving object and stretched behind the object. This stretching creates a long wavelength. Red light has a long wavelength (the longest of visible light), so we call this stretching red shift.
