A Doppler red-shift is a shift in recognizable features of a star's spectrum from
the wavelengths where we know they belong toward longer wavelengths. Such
a shift can be caused by the star's moving away from us, and that's how it's
interpreted when astronomers see it.
A Doppler blue-shift is a shift in recognizable features of a star's spectrum from
the wavelengths where we know they belong toward shorter wavelengths. Such
a shift can be caused by the star's moving toward us, and that's how it's interpreted
when astronomers see it.

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.
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.
Who discovered the Doppler red shift?
The Doppler redshift was discovered by Hippolyte Fizeau in 1848.
What effect is red shift an example of?
The Doppler effect.
What does a blue and red shift of absorption lines in a spectrum indicate?
Blue shift is a decrease of a signal's wavelength, and/or an increase in its frequency, due to the Doppler Effect. This indicates that the object is moving towards the observer.Red shift is the increase of a signal's wavelength, and/or a decrease in its frequency, due to the Doppler Effect. This indicates that the object is moving away from the observer.
Can red shift and blue shift exist on the same object at the same time?
Yes, if the object is spinning there will be red shifts on the half moving away and blue shifts on the half moving closer.This is one way tornadoes are detected using Doppler RADAR, the water droplets on one side of the cloud are moving away (red shift) while those on the other side are moving closer (blue shift), showing that the cloud is rotating.Solid spinning objects act the same and the rotation is detectable with Doppler RADAR.
What is droppler effect?
The Doppler effect is the mix of red shift and blue shift. For example when your walking down the street and a car drives up from behind you and you don't see it but hear it your hearing the blue shift of the Doppler effect. also same scenario but the car has passed and driving away in front of you then your hearing the red shift of the Doppler effect. hope that helps I'm in 8th grade might wanna check but I'm pretty sure that's right well that's what we learned today anyway...:)
What shift of color do you receive from stars as you get closer?
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
Does the Doppler effect only apply to sound waves?
No
Would a light source moving away from Earth appear blue shifted or red shifted?
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
A Doppler red shift indicates?
a star is moving AWAY FROM EARTH
Who developed the red shift method?
Christian Doppler, and Austrian Physcist .
