Challenges in Determining Our Galaxy's Structure

Visibility Issues

Determining the structure of our galaxy from within presents several challenges. One of the main obstacles is the visibility issues caused by interstellar dust and gas. As we are located within the Milky Way galaxy, our view of distant stars and celestial objects is often obscured by these dense clouds of dust and gas.

Measuring Vast Distances

Another challenge is the immense scale of space and the vast distances between stellar objects. The sheer size of the galaxy makes it difficult to accurately measure the distances between stars, planets, and other celestial bodies. This makes it challenging to map out the precise structure of the Milky Way.

Movement of Celestial Bodies

Furthermore, the continuous movement of celestial bodies within the galaxy complicates our understanding of its structure. Stars, planets, and other objects within the Milky Way are constantly in motion, making it akin to trying to decipher the structure of a whirlpool while being caught in its swirling currents.
