There are other galaxies. Between the galaxies, there's lots of mainly empty space, with a very tenuous gas.
Deep space refers to the empty regions of space in between star systems, galaxies, etc.

When you look at atoms at that small of a level, between them you actually have empty space- nothing at all like in space. Even between the nucleus and its electrons of an atom itself there is a lot of empty space.
We see the stars in the sky, from our perspective of being here on the Earth. Stars are grouped into galaxies of billions of stars, and there are vast almost-empty spaces between the galaxies.
Atoms are most likely packed in a closely packed arrangement, such as a face-centered cubic (FCC) or a hexagonal close-packed (HCP) structure. These arrangements allow for efficient packing of atoms with minimal empty space between them.
The amount of empty space in the Universe, between galaxies, is many times larger than the amount of space occupied by galaxies. This ratio depends on what part of the Universe you are looking at. For example, our galaxy has a diameter of about 100,000 light-years; the closest larger galaxy (M31) is at a distance of about 2.5 million light-years. However, that's just the Local Group; from the Local Group to another galaxy cluster, there is even more empty space.
All atoms are mostly empty space, as the electromagnetic repulsion between atomic nuclei keep them from reaching each other (except under extreme pressure, as in the center of stars).
Space is only empty in between the objects it contains... the galaxies - and the stars and their planets within the galaxies. The things which go into a black hole get compressed to an incredible density..... the whole earth compressed to the size of a pea, for example. This can happen because an atom is largely empty space itself.... there is a lot of emptiness between the protons at the centre and the electrons. The tighter an atom can be compressed, the tighter and denser the thing it comprises becomes.
There may not be any such place, but the farther you get from stars (including ours) the less matter you find. Presumably between galaxies you might find very empty space. Such a volume of space is called a 'vacuum'.
To a large extent, empty space. But there are also isolated stars and other objects, as well as dust and gas. It seems that the intergalactic gas in a galaxy cluster, though thinly spread, has about as much mass as all the galaxies!
The universe is organized into structures such as galaxies, which are made up of stars, gas, and dust. These galaxies are arranged in clusters and superclusters, with vast empty spaces in between. The overall structure of the universe is governed by gravity and the distribution of dark matter.
