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.

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.
Does the colour of a galaxy reflect its distance away from the earth?
No, however, we can determine whether a galaxy is moving towards or away from us, by looking at the shift in its spectrographic analysis. There are "red shifts" and "blue shifts" in spectrographic results. "Blue shifts" indicate that a galaxy is moving towards us, because the wavelength of the light emitted by the galaxy is compressed, causing it to shift to the blue end of the colour spectrum. "Red shifts" indicate that a galaxy is moving away from us, because the wavelength of the light emitted by the galaxy is being stretched towards the red end of the colour spectrum.
What are there flag colors of France?
Blue, white, and red. Blue, white, and red.
When shrek gets an arrow caught in his behind what kind of flower is Donkey sent to look for?
Blue flowers red thorns Quote: (Donkey running through bushes of Blue flowers red thorns), "Blue flowers red thorns, Blue flowers red thorns, Blue flowers red thorns. Oh this would be so much easier is I wasn't color blind!" Blue flowers red thorns Quote: (Donkey running through bushes of Blue flowers red thorns), "Blue flowers red thorns, Blue flowers red thorns, Blue flowers red thorns. Oh this would be so much easier is I wasn't color blind!"
What color was the French flag in the 1800s?
Blue,white,and red Blue,white,and red
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
Can a red shift and a blue shift exist on the same object at the same time?
No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.
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 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 does a red shift tell astronomers about stars or galaxies?
A red shift in the light emitted by a star or galaxy indicates that it is moving away from us. By measuring the amount of red shift, astronomers can determine the speed at which the object is receding and use this information to study the expansion of the universe and the distance to the object.
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
Observation of the shift of a star's spectrum toward red indicates it is moving away from us (redshift), while blue indicates it's moving closer (blueshift). By studying this shift in the star's spectrum, we can determine its velocity and distance from Earth, providing valuable information about its motion and location in space.
How is the red shift different than the blue shift?
Radiation from a source moving away from the observer is red-shifted. Radiation from a source moving towards the observer is blue-shifted.
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 colors do you mix for burnt orange?
True red and true yellow will give you orange, varying the amount of red will determine the colour of orange... start with a redder orange and add a bit of blue, this will bring the orange toward the brown tones, varying the amount of blue will adjust your colour until you have the one you want.
How does a red shift from a blue shift?
A red shift shows us that a object is moving away, while a blue shift shows us an object is moving toward us. Light that has been 'red shifted' has a longer wavelength when it reaches our eyes/telescopes/etc. than it had when it left the object. Light that has been 'blue shifted' now has a shorter wavelength. The reason stretching the wavelength is known as 'red shifting' is that, in the visible spectrum, red light has the longest wavelength. Blue light has a much shorter wavelength than red so when the wavelength is compressed, we call it blue shifting.
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.
What color changes purple to red?
Purple is already and combination of blue and red. You would have to eliminate the blue.
