Much the same as ours. Stars and planetary bodies, gas clouds etc
The light from the Andromeda galaxy is blue-shifted because the galaxy is moving towards us due to the effects of gravity and the expansion of the universe. This motion causes the wavelengths of light emitted by the galaxy to appear slightly compressed towards the blue end of the spectrum.
The Andromeda galaxy, also known as M31, is primarily composed of stars, gas, and dust. The stars in Andromeda are mainly older, with some younger stars found in its spiral arms. The gas in the galaxy consists of hydrogen and helium, along with trace amounts of other elements. The dust in Andromeda is made up of tiny solid particles, which play a crucial role in the formation of new stars.
Basically, the same characteristics that the stars in the Milky Way - our own galaxy - have. Aside from the fact that Andromeda is somewhat bigger, the two galaxies are thought by astronomers to be very much alike. When Edwin Hubble studied the Andromeda Galaxy in the early 20th century, he was able to discern within it several "Cephid variable" stars, which proved, among other things, that Andreomeda was a galaxy, like ours. Prior to that time, it was believed that the Milky Way was the only galaxy - the others were "clouds".
Empty space , maybe dark matter and dark energy. Then there are other galaxies (about 100 billion of them that we could see if we looked). A galaxy that is close to ours is Andromeda which may be similar in shape to the Milky Way (some recent research claims that the Milky was is not a spiral galaxy at all but a barred elliptical galaxy). Andromeda is about 2 million light years away.
The Andromeda system.
In 2.5 billion years.
The closest galaxy to the Milky Way is the Andromeda galaxy.

Ours is the Milky Way Galaxy. Some others are Andromeda, The Tadpole Galaxy, Centaurus A, Draco Dwarf, Papillion, and the farthest known galaxy, UDFj-39546284.

Roughly 25.4 Milky Ways.
No human probes, no. The Andromeda Galaxy is simply too far away. It is about 2.5 million light years away, meaning that even at the speed of light it would take 2.5 million years to reach it, and no manmade probe can travel anywhere near that fast. Currently the furthest man-made probe is about 16 light ours from Earth, and it took nearly 35 years to get that far. Though technically we have no way of knowing if there is intelligent life somehwere in the Andromeda Galaxy that might be exploring their own solar system with probes.
I am not sure who this question is directed too. Last I checked we are part of the Milky Way Galaxy. So you will be asking someone in the Andromeda Galaxy that will collide with ours. Last I checked ATT did not have 4g set there yet.
