Speaking generally, most objects in the universe are red-shifted, that is they appear to be moving away from us. There are exceptions to this, obviously. There are plenty of objects in our own galaxy that appear to moving towards us. Plus the Andromeda galaxy appears to be on a collision course with the Milky Way. Objects moving towards us would appear to be blue-shifted.

∙ 13y agoOne can only describe an object as having a redshift or blueshift if it can be observed from the outside. Since the universe cannot be observed from the outside, one cannot say that the universe itself is redshifted or blueshifted.
Many objects within the universe are redshifted or blue shifted when observed from Earth. Any object moving away from us is redshifted, and any object moving towards us is blueshifted.

That is not Correct,
Sirius A has a local proper motion, BLUE SHIFT, expressed by an attributed velocity of about −7.6 km/s, originally thought in 1868 to be receding at 40 Km/s.
Sirius A and B are Companion stars. They are only 8.6 light years away. These two are in a unique group of seven stars that are very close to us compared to others even within our own galaxy. Sirius B is a White Dwarf, and is observed to be shifted red, as expected in Einstein's Theory of General Relativity. The Red shift is primarily due to Gravitational Time Dilation. Translated to Velocity, the latest measurements from the Hubble Space Telescope, show V = 91 km/s.
ALL stars within our galaxy have some proper motion relative to us, and show red and blue shifts accordingly, or not very much if moving laterally rather than toward or away from us. This 'localized' red or blue shift is usually attributed to simple Doppler effects. Our Sun, and Solar System, orbits around the central mass of the Milky Way at about 220 Km/s.

∙ 13y agoRed shift is much more common, because of the expansion of the Universe. In fact, this was one of the major arguments used to prove the expansion. Most scientists are satisfied, nowadays, that the redshift is due to the expansion of the Universe.

∙ 7y agoBoth can be observed. However, redshift is observed for most galaxies, because of their distance (and the general expansion of the Universe).

∙ 7y agoRedshift, since the Universe is expanding. Only in the case of objects that are relatively nearby will the "proper motion" sometimes dominate, so that some objects actually move towards us.

What does it mean when the color of an object in the universe shifts toward red?
It is the color of the light shift. either red or blue, from an object, not the object itself, that determines if it is moving away( RED) from us or moving toward us (BLUE).
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.
How do red shifts were used by cosmologists to determine that the universe is expanding?
A Galaxy's red-shift can be used to determine how fast it is travelling away from you. The opposite is "blue-shift" which is what happens when the Galaxy is travelling towards you.The first astronomers, such as Edwin Hubble, to analyse the light coming from distant galaxies discovered that almost all of them were red-shifted, indicating that they were almost all heading away from us. This was the first indication that the universe was expanding.
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.
How is light red shifted?
Red shift works when galaxies or other bodies are moving father away. the light is stretched, ie it becomes redder. Blue shift is opposite.
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..
Why are red shift and blue shift effects useful in the study of the universe?
Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.
What did hubble discover as a result of studying red shift of distant galaxies?
that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.

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.
Where is the edge of universe?
the universe is infinite, proven by the continuing blue shift
What does it mean when the color of an object in the universe shifts toward red?
It is the color of the light shift. either red or blue, from an object, not the object itself, that determines if it is moving away( RED) from us or moving toward us (BLUE).
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.
What is red shift and blue shift why are these effects useful in the study of the universe?
Red shift and blue shift refer to the shifting of light towards longer or shorter wavelengths, respectively. These effects occur due to the Doppler effect, where light sources moving away from us appear red shifted, and light sources moving towards us appear blue shifted. By measuring the extent of these shifts in the light from distant celestial objects, scientists can determine their motion and velocity, providing valuable information for studying the structure, expansion, and dynamics of the universe.
