Edit : In astronomy, the Doppler effect is the change in wavelength of light caused by movement of a light source such as a star or a whole galaxy.
The term "red shift" refers to the increase in the light's wavelength from the
blue to the red end of the spectrum. This happens when a light source is
moving away from us.
I don't want to over complicate things, but there is a similar thing
called the "cosmological red shift ", but that's caused by the expansion
of space itself.
What else can I help you with?
Who discovered the Doppler red shift?
Christian Doppler, an Austrian physicist, is credited with discovering the phenomenon of the Doppler red shift in 1842. He observed that the pitch of sound waves from a moving object changes depending on the object's motion relative to the observer. His theory was later extended to light waves to explain the red shift observed in the spectra of distant galaxies.
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.
Where is Betelgeuse on Doppler Shift?
Betelgeuse is a red supergiant star located in the Orion constellation. Its light exhibits a small Doppler shift due to its motion relative to Earth, but this shift is not significant compared to its overall distance and size. The Doppler shift of Betelgeuse's light is mainly influenced by its own pulsations and variations in brightness.
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.
Which astronomer discovered the red shift?
The first astronomer to discover that a galaxies red-shift was larger the further away it was was Edwin Hubble in the 1920s.The first scientist to describe red-shift in stars was actually Hippolyte Fizeau in 1848, though he was a physicist and not an astronomer.That light should be effected in this way was suspected by Christian Doppler (after whom "The Doppler Effect" is named) as early as 1842.
What effect is red shift an example of?
The Doppler effect.

What is a Doppler red shift and a Doppler blue shift?
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.
What is it called when galaxies move away and the light waves become longer?
That is called a red shift or a Doppler shift.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
Where is Betelgeuse on Doppler Shift?
Betelgeuse is a red supergiant star located in the Orion constellation. Its light exhibits a small Doppler shift due to its motion relative to Earth, but this shift is not significant compared to its overall distance and size. The Doppler shift of Betelgeuse's light is mainly influenced by its own pulsations and variations in brightness.
What is an explanation of the Doppler shift?
The Doppler shift is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave. When the observer is moving towards the source, the frequency appears higher (blue shift), and when moving away, the frequency appears lower (red shift). This effect is commonly observed in everyday situations, such as the change in pitch of a siren as a police car passes by.
What does the amount of red Doppler shift indicate?
It indicates how fast an object is moving away from us.
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.
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 can you use Doppler shift in a sentence?
Doppler shift is the change in frequency of a wave that seems to occur as it moves. Scientists study the doppler shift to see whether stars are moving away from or toward our galaxy.
