Dust in the Milky Way blocks our view of galaxies located in those directions. The Milky Way is a barred spiral galaxy, and we are located within it, so as we look out at the night sky, we are looking through the disk of the Milky Way. Dust and gas within our own galaxy can absorb and scatter the light from more distant galaxies, making them harder to see.
