How are we able to know how extremely far galaxies look like? Shouldn’t they be completely covered/invisible because of the huge amount of celestial bodies that are closer to us?

Question

After a certain distance, won’t all the celebrities bodies create some sort of wall where we can’t see further?

Answer 1

Technically yes, but you underestimate how empty space is. There’s just not enough celestial bodies in the way to block the view.
