ones moving away from us

Above is the typical Doppler Explanation. Of course, the star could be even still relative to us, when you consider the gravity hole (as an explanation for the red shift).

How does the speed of the star affect the spectrum?

The speed of a star affects its spectrum through the Doppler effect. If a star is moving towards or away from us, the wavelengths of the light it emits will be shifted towards the blue (blue shift) or red (red shift) end of the spectrum, respectively. This shift can provide information about the star's velocity and direction of motion.


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 a red shift means that are moving closer to earth?

No. A red shift indicates that the object is moving away from the earth.


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 a red shift and what does it mean for a star?

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.


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 can you infer about a star that exhibits a red shift in its spectra?

A red shift in a star's spectrum indicates that the star is moving away from us. This is due to the Doppler effect, where the wavelength of light is stretched as the source moves away, shifting it towards the red end of the spectrum. This can be used to determine the star's velocity and direction of movement.


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

red shift


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


red shift?

red shift


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.
