Redshift measure the recession speed of stars and galaxies. These speeds are proportional to distance--the farther a star or galaxy is from a given location in space, the faster that entity is moving away from that location. This proportionality is given as Hubble's Law. In general, everything is moving away from everything else, and the furthe away, the faster the acceleration (local movements not included).

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.
What is an effect of the red shift?
The red shift is the phenomenon where light from an object is shifted towards the longer wavelength, making it appear more red. It is commonly used to measure the speed and distance of objects in space, such as galaxies moving away from us due to the expansion of the universe.
What equipment do scientists need to observe red shift?
Scientists can observe red shift using a spectrometer or a telescope equipped with a spectroscope. The spectrometer will measure the shift in wavelength of light emitted by celestial objects, which can indicate the red shift. Additionally, precise and sensitive telescopes are needed to capture high-quality data for accurate red shift measurements.
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.
What can i use to measure the speed of stars?

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.
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
