What else can I help you with?
How can you measure how fast the universe is expanding?
By using some method other than the Doppler effect to calculate the distance of a distant galaxy, and using the Doppler effect to see how fast it moves away from us. A galaxy's distance and how fast it moves away from us are roughly proportional.
What can the Doppler effect tell us about in astronomy?
It can tell us whether a star, or a galaxy, is moving towards us or away from us.
How and did they figure out about the big bang?
One important clue is the Doppler effect - the redshift of distant galaxies. It turns out that the greater the distance to a galaxy, the faster it moves away from us.One important clue is the Doppler effect - the redshift of distant galaxies.

Why are redshift and blueshift useful in the study of the universe?
Redshift and blueshift are manifestations of the Doppler effect. This lets us determine whether a star, or a galaxy, is moving towards us, or away from us.
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.
When did Mass Effect Galaxy happen?
Mass Effect Galaxy happened in 2009.
What does a distant galaxy having a greater red shift indicate about the universe?
A red-shift caused by the Doppler-effect indicates that the object is rapidly moving away from the observer.Note that at extreme distances, red-shift is not caused by the Doppler-effect, but primarily by the expansion of space between the object and the observer.
What is galaxy redshifted?
Galaxy redshift is much light the Doppler effect. If a galaxy is traveling away from us, the light that it emits and is seen by us is stretched out (the faster we are separating, the stronger the redshift), that means that the wavelegnth is stretched a bit, shifting the light towards red.
When was Mass Effect Galaxy created?
Mass Effect Galaxy was created on 2009-06-22.
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.
How do you demonstrate the red shift and Doppler effect?
Examine the light of hydrogen emissions from a distant galaxy. Compare that spectrum with that of hydrogen in a laboratory. You'll find that spectrum is identical EXCEPT that it is shifted towards longer wavelengths.
Who measured the distance of Andromeda Nebulae and named after him?
Andromeda Galaxy
