What is important about Hubble's discovery that there is a red shift the spectra of galaxies?
It is difficult to estimate the distance of astronomical objects without information about its intrinsic brightness. However, its spectrum will contain absorption lines based on elements, such as hydrogen and helium, in the outer regions of the object. This lines are characteristic of the elements and they are also red-shifted which allows the red shift to be measured more readily. The red shift is a measure of how fast the object is receding from the earth and, because the red shift is correlated with the distance from the earth, it provides a relatively simple guide to the distance of the object.
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 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.
What does red shift show?
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.

When was The Red Shift created?
The Red Shift was created in 2005-06.

What is the opposite of the red shift?
The opposite of the red shift is the purple shift.

What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.

How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
How does blue and red shift help us understand the changes of the universe?
Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..
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.
Need to know facts about red shift?
you should probably ask your docter about that if ur having red shift
