Redshift measure the recession speed of stars and galaxies. These speeds are proportional to distance--the farther a star or galaxy is from a given location in space, the faster that entity is moving away from that location. This proportionality is given as Hubble's Law. In general, everything is moving away from everything else, and the furthe away, the faster the acceleration (local movements not included).

What does red shift show?
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
What is important about Hubble's discovery that there is a red shift the spectra of galaxies?
It is difficult to estimate the distance of astronomical objects without information about its intrinsic brightness. However, its spectrum will contain absorption lines based on elements, such as hydrogen and helium, in the outer regions of the object. This lines are characteristic of the elements and they are also red-shifted which allows the red shift to be measured more readily. The red shift is a measure of how fast the object is receding from the earth and, because the red shift is correlated with the distance from the earth, it provides a relatively simple guide to the distance of the object.
What determines galaxy motion and distance?
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
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).
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
What can i use to measure the speed of stars?
Red shift.
What does red shift show?
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
When was The Red Shift created?
The Red Shift was created in 2005-06.

What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red 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).
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
How does blue and red shift help us understand the changes of the universe?
Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..
Who discovered the red shift?
In 1848, Hippolyte Fizeau first noted a red shift in stars. In 1912, Vesto Slipher first noted a large red shift in nebulae. In 1929, Edwin Hubble published his findings that the size of galaxy's red shift was proportional to its distance from our Earth.
