Who discovered red shift in the starlight from distant galaxies?
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)
Which astronomer discovered the red shift?
The first astronomer to discover that a galaxies red-shift was larger the further away it was was Edwin Hubble in the 1920s.The first scientist to describe red-shift in stars was actually Hippolyte Fizeau in 1848, though he was a physicist and not an astronomer.That light should be effected in this way was suspected by Christian Doppler (after whom "The Doppler Effect" is named) as early as 1842.
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.
What determines galaxy motion and distance?
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
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).
What is the name of the scientist that calculated the formula for the red shift?
Edwin Hubble.

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

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

What can scientist determine using red shift?
that stars are moving away from us, as if flung out from an explosion, helping support the big bang theorey and showing us that the universe is expanding
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).
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.
