Question

jane is observing the milky way thanks to the fact that it is a very clear, dark night. however, she feels like she can only see a very small part of it and wants to see the entire galaxy. why is this impossible?

because of the speed the earth is spinning

because it is always moving

because of her position within it

because the sun always blocks part of it out

Explanation:

To determine why Jane can't see the entire Milky Way, we analyze each option:

• "Because of the speed the Earth is spinning": Earth's spin affects night - day and star movement over time, not the ability to see the entire galaxy at once. So this is incorrect.
• "Because it is always moving": The Milky Way's movement doesn't prevent seeing the entire galaxy from our position. So this is incorrect.
• "Because of her position within it": We are inside the Milky Way (in the Orion - Cygnus arm). From within a galaxy, we can't see its entire structure as our view is blocked by stars, gas, and dust in our line of sight, and our position limits the perspective. This is the correct reason.
• "Because the Sun always blocks part of it out": The Sun is within the Milky Way and doesn't block the entire galaxy from view. So this is incorrect.

Answer:

C. because of her position within it
