Imagine that an observed distant galaxy is measured to have a distance of 20 Mpc by a Type Ia supernovae and the redshift of the galaxy indicates the galaxy appears to be moving away from us at a speed of 2200 km/s. What would the Hubble constant be if measured solely based on this galaxy in units of km/s/Mpc?
The Virgo cluster has a distance of about 17 Mpc from the earth. Using Hubble's law, determine the recessional velocity Vr to this cluster.
why is it difficult to measure the Hubble constant?

- The best parallaxes obtained with Hipparcos have an accuracy of 0.001 arcsec. If you want to measure the distance to a star with an accuracy of 10%, its parallax must be 10 times larger than the typical error. How far away can you obtain a distance that is accurate to 10% with Hipparcos data? The disk of our Galaxy is 100,000 light-years in diameter. What fraction of the diameter of the Galaxy’s disk is the distance for which we can measure accurate parallaxes?arrow_forwardSuppose you were Hubble and Humason, working on the distances and Doppler shifts of the galaxies. What sorts of things would you have to do to convince yourself (and others) that the relationship you were seeing between the two quantities was a real feature of the behavior of the universe? (For example, would data from two galaxies be enough to demonstrate Hubble’s law? Would data from just the nearest galaxies-in what astronomers call “the Local Group”-suffice?)arrow_forwardWhen comparing two isolated spiral galaxies that have the same apparent brightness, but rotate at different rates, what can you say about their relative luminosity?arrow_forward
