1) Sive a detailed description of how you determined the distance to the Virgo Cluster. (10 pts) 2) If you were careful in your determination of the distance to the Virgo Cluster, you should have found that it lies within 1 Gasmeaning that your distance determination can be checked with the help of a standard candle. Recall that all Type 1 Supernovae have the same luminosity Luckily, a pair of Type 1 supernovae were observed in the Virgo Cluster in 2013. One of these was named Everest. Everest had an apparent brightness of 1019x10-1 W/m2Use this information, along with the known luminosity, to determine the distance to the Virgo Cluster. (20 pts) 3) How did your estimated distance to the Virgo Cluster compare with your value found from the supemova Everest? Were your values cose? If not, what might be some reasons for the discrepancy? (10 pts)
4) What was the difference between these values? (5 pts) I 5) Now look up the actual distance to the Virgo Cluster. How close were your calculations to the actual value? Which calculation was closer? The distance obtained from Hubble's law or the one obtained from Everest? (10 pts)
