The change of frequency of waves, depending on relative movements, is usually attributed to Mr. Doppler.
The fact that most galaxies move away from us (as evidenced by the redshift) is the result of the work of Mr. Hubble.

Explain why some stars in the milky way galaxy have a blue shift Doppler effect and other stars in the milky way have a red shift Doppler?
A blue-shift means an object is moving towards us, a red-shift means it is moving away from us. Blue-shift and red-shift are changes in frequency of the light we receive, due to the relative movement. This is called the Doppler effect.
The spectral lines of elements when observed in distant galaxies show a shift towards?
The red end of the spectrum.
What does the amount of red or blue shift determine?
Red Shifting happens when an object is moving away from us. The red shifting we observe when looking at distant galaxies over time tells us that they are moving away from us; the Universe is expanding. Blue shifting would happen in the opposite scenario. You can see blue shifting if you looked at the outer perimeter of any Galaxy as since they are constantly spinning, one side will always be heading towards you...to explain this further: Draw a dot on the outer-edge of the frisbee. Now have the frisbee spinning in front of you counter-clockwise. For each rotation, the dot is moving towards you. That will be a blue shift. Now since the Universe is expanding, the frisbee itself is also movign away from you -- that is a red shift.
What contributions did newton and Galileo make to astronomy?
Galileo founded the science of Astronomy by observing with the telescope, the heavenly bodies were objects to be studied like on earth. Newton with the Law Gravity introduced theoretical Astronomy and made science Universal. Newto also created calculus and the reflective telescope. He mastered phyiscs. His Principia is the start of Mathematical Physics. Hubble extended the Univerrse beyond our solar system, identifying nebulae as galaxies and establishing their far distance and finally developed the linear distance Law of red shift. Hubble had the integrity to say he did not understand the red shift. He said the red shift is "an hitherto unrecognized priniciple of nature". He did not believe it represented an expanding universe. I have theoretically derived the red shift and Hubble is correct, the red shift indicates Continuity Condition (Fermion force), the balance of centripetal force and centrifugal force vp/r=cp/r cos(P) thus v/c= cos(P) where cP is the "dark energy". The Universe is not expanding, it is bounded at v=c. the red shift rather indicates contraction to gravitational center. Red shift occurs in atoms, solar systems and Galaxies. Physicisrs today ignore Hubble's conclusions but Hubble is correct and the Big bang and Expanding Universe is false. The Universe is a bounded Quaternion Space, W = -vh/l + cP.
According to Hubble's law what do the farthest galaxies in the universe appear to be doing?
Receding from each other faster the farther away they are. He saw they were "red shifted" and the red shift was greater the farther away the galaxy was. This mean that the Universe is expanding.
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 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 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).
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.
Who is the discoverer of the salt?
A discoverer of salt is not known.
Who discoverer the protein angiostatin?
who is the discoverer of protein
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.
