It's a change (decrease) in the frequency of the light we receive from the star. Equivalently, an increase in the wavelength. It usually means the star is moving away from us, though it might also be caused (usually to a lesser extent) by the star's gravitation.

How does the speed of the star affect the spectrum?
As a star moves away from us it has a red color shift.
A Doppler red shift indicates?
a star is moving AWAY FROM EARTH
What does it mean when an astronomers observing starlight wa spectrograph notices shift at off lines to the red end of spectrum?
The star is moving away fro where it is. ~Justine... :))
Does a red shift indicates that objects are moving toward earth?
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
What can you infer about a star that exhibits a red shift in its spectra?
It is moving away at a significant speed.

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.

What is an effect called in which a star or galaxy appears to move away from an observer?
red shift

It is moving away at a significant speed.
What is an area that's not currently being studied?
Hubble's red shift is due to movement, however, a large mass (star) will gravitationally cause a red shift. The former is studied; the latter is not.
What turns red in the red shift?
light is put into a spectrum from red to blue. red shift is when a star is moving away from us so fast that the light waves stretch moving it up the spectrum, so up towards infared
Observation of the red shift of galaxies suggest that the universe is what?
Expanding Or that the light is exiting a gravity hole (star).
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
What does it mean if a star is experiencing a red shift?
redshift is what happens when visible light gets longer in wavelength, thus shifting toward the red end of the spectrum of visible light. This is a phenomenon that occurs when the light source is moving away from the observer.
