Answer to Problem 1VSC
Solution:
Cepheid variable stars technique is used to measure a distance of 10 million light-years.
Explanation of Solution
Introduction:
Effective technique is used to measure a large distance between astronomical objects.
Cepheid variables stars are extremely luminous and can be observed and measured at a large distance. There is a definite relation between the period and luminosity of Cepheid variables. With the help of period-luminosity relation large distance such as between galaxies can be found.
Conclusion:
Cepheid variables stars
