WebWhat is the redshift of this galaxy? What is the recession speed of this galaxy? Answer: Because this is the same galaxy, we could pick any one of the four wavelengths and calculate how much it has shifted. If we use a rest wavelength of 410 nm and compare it to the shifted wavelength of 492 nm, we see that WebThere are really two kinds of redshifts, each with its own interpretation. Some redshifts are dynamic - they arise from moving objects (for example, two stars in orbit around each other); other redshifts arise from the cosmological expansion of space described above.
