What conclusion do astronomers make based on the red shift?
use your brain to answer it its ok for your answer.
The red shift of visible light waves that is observed by astronomers on earth is used to determine the?
The speed of relative retreat of the star.
What does it mean when an astronomers observing starlight wa spectrograph notices shift at off lines to the red end of spectrum?
The star is moving away fro where it is. ~Justine... :))
What is important about Hubble discovery that there is a red shift in the spectra of galaxies?
that the universe is expanding(: YouR WelomE
What does a red shift tell astronomers about the movement of an object?
"Redshift", which means that the frequency of the light as seen by us is LESS than the frequency at which it was emitted, tells us that an object is moving away from us.

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

Does the absorption spectra tell astronomers if a star is moving towards the earth?
Yes, or at least it is used in determining that. However, it is only part of a much larger calculation in determining if it has a red or blue shift

What do astronomers use measure to distances to nearby stars?
Two units that are commonly used are:* Parsecs (among professional astronomers) * Light-years (in popular astronomy) A light-year is about 9.5 million million kilometers. A parsec is about 3.26 light-years.
When was The Red Shift created?
The Red Shift was created in 2005-06.
What is important about the Hubble telescope's discovery that there is a red shift in the spectra of galaxies?
The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.
What is it important for astronomers to study the sun?
SSo the astronomers can tell us what is happening to the sun. that good enough? :)
