No. You can figure out exactly what elements are in stars and galaxies by examining the color spectrum of the light detected; the frequencies of the bright and dark lines in the spectrum tell you what's what. But there's a problem.
For distant galaxies, the light spectrum is wrong. The frequency lines of the spectrum are all too low. One possible explanation of the incorrect spectrum is that those stars and galaxies are MOVING AWAY from us, and that the spectrum is shifted toward the red end of the color spectrum because of the Doppler effect.
So scientists believe that the "red-shift" on the color spectrum of stars and galaxies indicate that they are moving away.
Not all galaxies show a red-shift; the Andromeda Galaxy, M31, shows a pronounced BLUE-shift, indicating that it is heading TOWARD us. In fact, scientists believe that the Milky Way and Andromeda will probably collide in about 3 billion years.

∙ 11y agoThis statement does not make sense; a redshift does not mean red color. For example, a blue galaxy with a small redshift will still appear blue.

What Doppler shift do galaxies show?
Some nearby galaxies move towards us (blueshift), some move away from us (redshift). Galaxies that are farther away all move away from us (redshift); this means that the Universe is expanding.
Nearby galaxies may not show a redshift?
Nearby galaxies won't show much of a redshift, because they aren't moving away very quickly - or at all. For example, the Andromeda Galaxy, M31, is actually getting closer - and will collide with the Milky Way in about 3 billion years.
What are galaxies which show no distinct feature or symmetry called?
Irregular galaxies show no distinct feature or symmetry.
What color light must a row boat show after dark?
white
What color light must show on the left side of the boat?
Red
What color light must show on port side of boat?
Red
What other galaxies do you have in unniverse?
For a start, look up "Local Group" in the Wikipedia. This will show you a list of nearby galaxies.
What are the strengths and weaknesses of the redshift theory?
cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding
The redshift of light from distant galaxy provides evidence that the universe is?
The red shifts show the galaxies are under centripetal force and the red shift indicates the centrifugal force. This indicates that the universe is in continuity, the centripetal and centrifugal forces are in balance.
What color must show on the starboard side of a boat?
Port (left) is red.Starboard (right) is green.
A powerboat is operating at night. Which color light must show on the port side of this boat?
RED
What does the Hubble telescope deep field image show?
Galaxies. Billions OF billions of galaxies. To quote Isaac Asimov; "The Stars, Like Dust..."
