The elliptical galaxy NGC 4889 is the largest galaxy in the Coma Cluster (shown in the image below taken by the Hubble Space Telescope). After analysing the spectrum of NGC 4889, an astronomer identifies a spectral line as being CaII (singly ionised Calcium) with a measured wavelength of 401.8 nm. The true, rest wavelength of this spectral line, measured in a lab, is 393.3 nm. Using a Hubble constant of ?0 = 70 km/s/Mpc, find the distance to this galaxy cluster. Give your answer in megaparsecs and in light-years.

Scientists observe a distant galaxy with a spectrometer. They find that the wavelength of the Lymann alpha Hydrogen line in the stars spectrum has shifted from its laboratory value of 121.6 nm to three times that value, 364.8 nm. According to the doppler effect, how fast is the galaxy receeding from us? (Find v/c of the galaxy relative to us).

- A neighboring galaxy rotates on its axis so that stars on one side move toward us as fast as 200 km/s, while those on the other side move away as fast as 200 km/s.
