The short answer to this question is "everywhere".
Redshift is one aspect of the Doppler effect of light. An observer, looking at an object that emits light, will see the apparent wavelength of that light either compressed to shorter values (if the object is moving toward the observer) or stretched to longer values (if the object is moving away from the observer). Since red light has a longer wavelength than blue light, a stretched wavelength is referred to as a "redshift".
It turns out that all of the galaxies in the Universe are moving away from our galaxy, save for a few that are gravitationally bound together into the Local Group of galaxies to which the Milky Way belongs. Therefore, in every direction you look, the sky is full of redshifted galaxies.
Within our galaxy, stars have random motions in addition to their general orbits around the galactic center. Some of those motions result in blueshift, some in redshift. So you can find blueshifted stars in every direction you look. But the stars are very local, distance-wise, compared with the redshifted galaxies.

Why the red shift in light from distant galaxies indicate that the universe is expanding?
Red shift is observed in the spectrum of light from an object when it is moving away from the observer. Most astronomical objects display a red shift in their light. Also, the red shift is greater for objects which are further away. For this to happen - in all directions, the universe must be expanding.
How are Doppler blue and red shift different?
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
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.
In the universe what is the red shift?
The alterations to the electromagnetic spectrum caused by the expansion of the universe.
How does red shift support the steady state theory?
Red shift supports the steady state theory in that the red shift indicates the Continuity Condition. Steady State means Conservation of Energy and does not require an expanding universe. It is the misunderstanding of red shift that adds the requirement of an expanding universe and the need for continuous creation.Hubble saw red shift as a "hitherto unrecognized principle of nature", not an expansion of the universe. less prudent physicists have misunderstood red shift. Red shift is an indicator of "continuity condition" and the result of centrifugal force balancing gravitational centripetal force.Steady State is the proper term for Conservation of Energy or Homeostasis, which seems to characterize the universe. "Steady State Theory" without expansion is well supported by red shift.The proper Theory of Gravity, E = -mu/r + mcV, accounts for 'dark Energy and red shift" and a finite universe.

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..
What is hubb?
Presuming you mean "Hubble's Law," it is an observed fact that, the further an object is from our Earth, the greater is the red shift of its emitted light. What has been been undeniably observed can only be explained by an ongoing expansion of our Universe.
Scientists' evidence for an expanding universe is called a because the light waves emitted by stars and galaxies are shifting toward the end of the visible color spectrum.?
Many objects observed in the universe show a red shift. It is believed that this red shift is caused by a Doppler effect - that is, that the objects are moving away from us at a significant fraction of the speed of light. If this is true, then it is evidence for an expanding universe.

What does red shift of the universe show is us?
universe is expanding at an accelerated rate.
What model of universe supported by red shift?
The universe expanding in all directions.
In the universe what is the red shift?
The alterations to the electromagnetic spectrum caused by the expansion of the universe.
What are the best indications that the universe is expanding?
A misunderstanding of red shift is the indicator is expanding. The correct understanding of red shift indicates the universe is in continuity, not expanding and is finite. RED SHIFT OF DISTANT GALAXIES.
