It means they are moving away from us.

What does red shift tell us about other galaxies?
Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to 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.
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?

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
What is it called when galaxies move away and the light waves become longer?
That is called a red shift or a Doppler shift.
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).

What does the big bang theory involve?
Red shift caused by the galaxies moving apart.

expanding
What is the relationship between red-shift and distant galaxies?
Redshift is the phenomenon where light from distant galaxies appears to be shifted towards longer (redder) wavelengths. This is due to the expansion of the universe causing the galaxies to move away from us. The amount of redshift is directly related to the distance of the galaxy from us, with more distant galaxies experiencing higher redshift.
