Vesto Slipher and Edwin Hubble were the first who discovered a red shift in nearby Galaxies and as telescopes improved the formula could be applied to more distant Galaxies. The instrument that determines red or blue shifts is called a Spectroscopy.
Ans. 2
The person who discovered (and explained) red-shift in the light from other galaxies was Vesto Slipher.
Edwin Hubble, using Slipher's observations, realised that the amount of red-shift was proportional to the distance of the galaxy being observed. He formalised this as "Hubble's Law". This was what led cosmologists to the conclusion that the Universe is expanding. (see * below)
The instrument that shows a spectrum is a spectroscope; that which measures it is a spectrometer and that which records it is a spectrograph. The instrument that measures red-shift of a distant galaxy can be anything from a travelling microscope to a ruler, depending on the quality of the photographs. Spectroscopy is the name of a set of processes, like Photography or cookery , not any particular instrument.
* The larger stars/galaxies are visible from further away. The larger stars/galaxies have a larger red shift without regard to their distance from us. (re: larger means more gravity means more red shift)

What is the relationship between red-shift and distant galaxies?
red shift is a distance and galaxies are planets. galaxies are also chocolate bars and red shift is not. thanks for your time. now go use your own knowledge and stop using google you gimps.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
What did hubble discover as a result of studying the red shift of distant galaxies?
that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.
What is red-shift and what does the size of the redshift tell us about the distant galaxies?
Red shift is the apparent elongation of the wavelength of light reaching us from distant sources of light due to the expansion of space in between. The amount of red shift can be used to work out the recessional velocity of a galaxy and it's distance from us.
Why the red shift in light from distant galaxies indicate that the universe is expanding?
Red shift is observed in the spectrum of light from an object when it is moving away from the observer. Most astronomical objects display a red shift in their light. Also, the red shift is greater for objects which are further away. For this to happen - in all directions, the universe must be expanding.
What kind of Doppler shift did Hubble observe in these distant galaxies?
Most galaxies exhibit a redshift, meaning that they move away from us.

The spectral lines from distant galaxies do not match spectral lines on Earth due to?
wavelength shift
What are the spectral lines of starlight from distant galaxies?
They are the characteristic frequencies of the elements "burning up" in the stars in the galaxy interspersed with absorption lines of other material between these elements and the earth. All these wavelengths will be increased by the red shift which results from the galaxy receding from the earth.
The spectral lines of elements when observed in distant galaxies show a shift towards?
The red end of the spectrum.

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 measurement was Edwin Hubble famous for?
Edwin Hubble was famous for measuring the red shift of distant galaxies and interpreting that as evidence of the expansion of the Universe.
When viewed from earth the light from very distant galaxies shows a red shift evidence that these distant galaxies moving towards or away from earth?
The "redshift" refers to the fact that the light is less energetic than when it was emitted; it shows that the galaxies move away from us. Should a galaxy move towards us - which is possible only for galaxies that are relatively close to us - then there would be a blueshift.
