Redshift (km/s) 1000 + Virgo Cluster + 20 10 Distance (Mpc) The universe is expanding according to Edwin Hubble's famous equation v = Hod where v is the velocity of a galaxy at distance d away. Professional astronomers usually talk about Hubble's Constant in the weird units of Ho = 70 km/sec/Mpc. This final unit, "Mpc" is the "Megaparsec" and it equals approximately 3 million light years. This is a powerful equation. It allows us to predict how far away a galaxy is if we measure the speed it is moving away from us (this is done by measuring the redshift of the galaxy). If a galaxy is measured to have a recessional velocity of v= 1300 km/sec. How far away in Megaparsecs do you estimate the galaxy is from us? Mpc
