A weird thing approximately astronomy is that one of the hardest things in the entire Universe to understand is the Milky Way galaxy.
It’s like knowing a lot approximately your neighborhood,the nearby city, and even your state, and but not really knowing much approximately your own house.
To be fair,it’s like trying to understand your house but not being allowed to leave your closet. We’re inside the Milky Way, stuck approximately halfway out from the middle, and everything we learn approximately it we learn from proper here. The good news is we humans are really,really clever.
