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.

What is the Doppler shift as it applies to light from stars?
You've probably heard the old classical description of the Doppler effect; if you're standing still near a train track, you can hear the sound of the moving train shifted to a higher frequency as the train is coming toward you, and as the train passes by, you can hear the sound shift down in pitch. The sound waves are bunched up a bit as the train is coming toward you, and you hear the train at an increased tone; when the train passes by and moves away from you, the sound waves are stretched out so you hear the sound at a lower pitch. By measuring the change in the sound, you can calculate quite accurately how fast the train was moving when it passed by. For stars, we're not listening to a tone; we're measuring the light spectrum, but the principle is the same. We know what the "normal" frequencies in the starlight would be, for a star not moving towards us or away from us. We measure specific spectrum patterns called "absorption lines". We can detect shifts in these patterns. So, we can measure whether the star is coming toward us (spectral lines at higher frequencies than normal) or is headed away from us (spectrum showing lower frequencies than normal). When we measure the light - and the Doppler shift - of other stars in our Galaxy, we see a mix of stars moving toward us, and stars moving away from us. This is perfectly normal. But when we measure the Doppler shift of the light from other galaxies, we see that most of the other galaxies are moving away from us, and that the farther away they are, the faster they are moving! Note: For those who like a bit of extra detail: The change in the light from distant galaxies is not a true Doppler shift. It's similar, but is caused by the expansion if space itself.

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.
Why is there no Doppler shift when a star is moving tangentially?
Because there is only a shift if the object's distance is changing.
If we observe a Doppler blue shift from a star the star must be a?
In that case, the star must be approaching us.
How do you find the speed a star using Doppler shift?
To find the speed of a star using Doppler shift, you can measure the change in the wavelength of light emitted by the star. If the light is redshifted, the star is moving away from us; if it is blueshifted, the star is moving towards us. By analyzing the amount of shift, you can determine the star's speed relative to the observer.
What phenomenon accounts for the blue shift of a star moving towards Earth?
The Doppler effect
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.
Which object would best be identified by a periodic Doppler shift in a star's spectrum along with a dip in the star's light intensisty?
An exoplanet would best be identified by a periodic Doppler shift in a star's spectrum, known as the radial velocity method, along with a dip in the star's light intensity, indicating a planetary transit. When an exoplanet orbits its star, it causes a detectable Doppler shift in the star's light due to its gravitational pull and blocks a portion of the star's light when it transits in front of it.
How can astronomers determine whether a star is moving toward or a way from earth?
They can do so by examining the light from the star. Doppler shift can indicate this
How do the spectra of some stars shift?
There is a Doppler shift which results from the relative motion of the star in question, either toward or away from us as we observe it.
The apparent shift in the spectrum of a star as it moves toward or away from the earth is explained by the phenomenon known as the?
Doppler effect. This effect causes the wavelengths of light from a star to appear shorter (blueshifted) as it moves towards the Earth and longer (redshifted) as it moves away, providing valuable information about the star's motion in space.
What is a Blue shift star?
A blue shift star is a star that appears bluer than normal due to its motion toward Earth, causing a shift of its spectral lines towards the blue end of the spectrum. This phenomenon is known as the Doppler effect and is used in astronomy to study the movement of celestial objects.
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.
