Question
r the course of history, many astronomers and scientists made observations about our solar system and galaxy. se observations provided evidence for the existence of the Milky Way galaxy and the location of our solar system in it. Which of these are evidence that helped to lead to this discovery? Select Two correct answers. Ulugh Beg discovered the angle at which Earth's axis is tilted. Ancient astronomers were able to view the stars with the unaided eye. Scientists at the Large Hadron Collider found evidence to support the existence of the Higgs boson. Immanuel Kant suggested the solar system might be a rotating body of stars that is held together by gravitational forces. Harlow Shapley used globular clusters to show where we "live" in our galaxy and to estimate the size of the Milky Way galaxy.

Answer
The two key pieces of evidence that helped discover the Milky Way galaxy and our solar system's location within it are:
1. **Immanuel Kant's idea** that the solar system is a rotating body of stars held together by gravity.
2. **Harlow Shapley's use of globular clusters** to map the Milky Way's structure and estimate its size, showing our position within it.
These discoveries were crucial in understanding our place in the universe.
Solution
The discovery of the Milky Way galaxy and the determination of our solar system's location within it were significantly influenced by several key observations and theories. Among the options provided, the two that most directly contributed to this understanding are:
1. **Immanuel Kant suggested the solar system might be a rotating body of stars that is held together by gravitational forces.**
- **Explanation:** Immanuel Kant proposed the nebular hypothesis, which suggested that the solar system formed from a rotating cloud of gas and dust. This idea was foundational in understanding that stars could be part of a larger, gravitationally bound system, laying the groundwork for the concept of galaxies like the Milky Way.
2. **Harlow Shapley used globular clusters to show where we "live" in our galaxy and to estimate the size of the Milky Way galaxy.**
- **Explanation:** Harlow Shapley's observations of globular clusters allowed him to map out the Milky Way's structure. He was able to determine that the Sun is not at the center of the galaxy but is instead located in one of its spiral arms. Additionally, his work provided estimates for the galaxy's size, further establishing our place within it.
These two contributions were pivotal in advancing our understanding of the Milky Way and our position within it.
**Correct Answers:**
- Immanuel Kant suggested the solar system might be a rotating body of stars that is held together by gravitational forces.
- Harlow Shapley used globular clusters to show where we "live" in our galaxy and to estimate the size of the Milky Way galaxy.

Ancient astronomers, with their sharp eyes and curiosity, gazed up at the night sky, documenting the positions and movements of stars without any fancy telescopes. Their observations laid the groundwork for understanding the structure of our galaxy, and with enough star-gazing, they began piecing together the vastness of the Milky Way. In the early 20th century, Harlow Shapley stepped into the limelight with his groundbreaking work on globular clusters. By mapping these dense star collections, he not only pinpointed our location within the Milky Way but also helped estimate the galaxy's size, revealing just how small our solar system is in the grand cosmic dance!
