The red shift spectra of galaxies show that most galaxies are moving away from us, indicating that the universe is expanding. This observation supports the Big Bang theory, which suggests that the universe began in a state of high density and temperature and has been expanding ever since. The amount of red shift in a galaxy's spectrum can also provide information about its distance from us and its velocity.

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 theory does red shift support?

Red shift supports the theory of the expanding universe proposed by Edwin Hubble. The observed red shift in the spectra of distant galaxies indicates that they are moving away from us, providing evidence for the idea that the universe is continuously growing and expanding.


What is the significance of red shift galaxies?

It means they are moving away from us.


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.


Who discovered the Doppler red shift?

Christian Doppler, an Austrian physicist, is credited with discovering the phenomenon of the Doppler red shift in 1842. He observed that the pitch of sound waves from a moving object changes depending on the object's motion relative to the observer. His theory was later extended to light waves to explain the red shift observed in the spectra of distant galaxies.


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.


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 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.
