I understand that the Hubble Space Telescope is able to see these distant galaxies we discover, but how exactly does Hubble do that? I have heard the analogy that our galaxy and our place in it is like being in the middle of a forest. If we look any direction, we cannot see outside the forest because we are blocked by the very same forest. That is like we cannot see outside of our galaxy, because the light from our own galaxy is not allowing us to do that. Since the Hubble Space Telescope can see in forms of light outside the visible spectrum, is this why it is able to see "through" our galaxy to discover more distant and older ones?
