The Andromeda galaxy covers a relatively small fraction of the observable universe. It is estimated to be around 220,000 light-years in diameter, making up just a tiny portion of the vast expanse of the universe.
No, the Andromeda Galaxy is not bigger than the universe. The universe is vast and contains billions of galaxies, including the Andromeda Galaxy. The universe is much larger in scale and encompasses everything that exists.
Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.
There are at least 27 known dwarf galaxies orbiting the Andromeda galaxy. These small galaxies are gravitationally bound to Andromeda and are much smaller in size and mass compared to the main galaxy.
About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.
Lmao, 220,000ly gaalxy vs. a dwarf star that has a diameter of 1.3mln km lmao it's obvious Andromeda is a bigger

The Andromeda Galaxy is spiral shaped, much like our own Milky Way Galaxy.See related link for a pictorial.
the universe apparently never stops going. Plus the galaxy's are included with the universe :)
It is extremely likely, but we cannot yet find planets from that far away. All the planets we have found to date are in our own galaxy. The Andromeda galaxy is 2.5 million light years away whereas our galaxy is about 100,000 light years across.
Much the same as ours. Stars and planetary bodies, gas clouds etc
Although the Andromeda Galaxy is a bit larger than the Milky Way, and is large as spiral galaxies go, it is not the largest galaxy. There are larger spiral galaxies, and much, MUCH larger elliptical galaxies. However, because it is relatively close to the Milky Way, the Andromeda Galaxy _appears_ quite large, spanning an apparent width roughly six times that of a full Moon. Still, there are two smaller, closer galaxies (the Magellanic Clouds) which appear larger still. (The Magellanic Clouds are not visible from northern latitudes, however, so one could argue that the Andromeda Galaxy is the biggest galaxy in _apparent size_ visible from most of the northern hemisphere.)
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".
A galaxy cluster consists of several galaxy groups, each of which in turn contains several galaxies. So no; a galaxy cluster is MUCH bigger than any individual galaxy.
