Question
Chapter 14, Problem 1RD
To determine
The information that can be gained from the globular clusters.
Expert Solution & Answer
Answer to Problem 1RD
By understanding the distribution of the globular clusters, one can determine the location of the planet within the galaxy.
Explanation of Solution
Globular clusters are the spherical group of starts that can be found near the galaxies. A typical galaxy can contain up to a few hundred globular clusters. The Milky Way galaxy consists of about
Most of the galaxies contain globular clusters thus; these clusters would be old, because of which it can be used to determine about the universe.
Conclusion
Astronomers across the Earth have used the properties of the globular clusters to gain the information about the Milky Way galaxy as well as for the other galaxies too, such as the approximate age of the universe, the position of the sun in Milky Way galaxy, the evolution of the galaxies, and the center of the galaxy.
