First glance issues: modifiers, pronouns.

A. Surrounded by smaller spiral-shaped ‘satellite’ galaxies such as the Triangulum galaxy, astronomers who observe it speculate that the Andromeda galaxy

Astronomers can't be surrounded by galaxies....well, they could, but that's not the intended meaning. It almost looks like it refers to Triangulum galaxy...but further reading suggests 'it' does not. That's not good.

B. Astronomers observe the Andromeda galaxy, speculating that it is surrounded by smaller spiral-shaped ‘satellite’ galaxies and that it

This section about speculating the galaxy being surrounded by smaller galaxies alters the meaning of the original sentence. The astronomers aren't speculating the Andromeda surroundings; they're certain of the surroundings. They're uncertain about the Milky Way collision.

C. Astronomers observing the Andromeda galaxy, which is surrounded by smaller spiral-shaped ‘satellite’ galaxies such as the Triangulum galaxy, speculate that it

Looks good to me! Works because the "which" is preceding an extra description of the galaxy and is not a essential clause.

D. Astronomers who observe it speculate that the Andromeda galaxy, which is surrounded by smaller spiral-shaped satellite galaxies such as the Triangulum galaxy and which

'It' isn't necessary. The "which" section eliminates the crux of the sentence.

E. Observing the Andromeda galaxy and surrounded by smaller spiral-shaped satellite galaxies such as the Triangulum galaxy, astronomers speculate that it

Again, astronomers cannot be "surrounded by smaller spiral-shaped galaxies"!
