We can't be sure. The only thing we know for sure is that it could be explained as
the speed with which that galaxy is receding from us. If that's actually the cause
of the red shift, then from all the red shifts that we observe, we have to conclude
that all of the distant galaxies are receding from us, and the farther away one is
already, the faster it's receding. If all of that is true, then the whole universe is
expanding. This is the research that made Hubble famous.
Well said, but there is another reason. Maybe the light is coming from a large star (gravity hole, red shift due to gravity).

What is the relationship between red-shift and distant galaxies?
red shift is a distance and galaxies are planets. galaxies are also chocolate bars and red shift is not. thanks for your time. now go use your own knowledge and stop using google you gimps.
What is the significance of red shift galaxies?
It means they are moving away from us.
What does red shift tell us about other galaxies?
It tells us that most galaxies are moving away from us.
How does red shift differ between galaxies close to us and ones which are further away?
Generally, the galaxies that are further away will have the larger red shifts.
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
The spectral lines of elements when observed in distant galaxies show a shift towards?
The red end of the spectrum.

What is red shift inti?
When galaxies move away from us, the waves of light stretch out- ie, they become redder. The greater the red shift, the faster the galaxies are moving away from us.

Do galaxies moves away from the sun by red shift?
Galaxies that are moving away from the sun are red shifted, that is the light from them looks more red to us that it is when it is emitted. This is due to the speed of the galaxy moving away from which in effect stretches out the wavelengths of the light. Red shift is not the method by which galaxies move away from the sun, rather, it is a consequence of it.
What is important about the Hubble telescope's discovery that there is a red shift in the spectra of galaxies?
The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.
What observation of the light from galaxies shows that nearly all galaxies are moving away from us?
The Red Shift or Doppler effect
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
What is it called when galaxies move away and the light waves become longer?
That is called a red shift or a Doppler shift.
How is the universe changing by red shift?
the universe is changing by red shift because when red shift occurs it means that galaxies and stars are moving away from us. this means that the whole universe must be expanding.
