The closest galaxy to the Milky Way is the Andromeda galaxy.
The other galaxies around ours and their contents.
Universe is describing the galaxies. There are different galaxies and our galaxy is called Milky Way Galaxy. There are some other galaxies miles away from ours.
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
You can infer that the universe is getting larger.
there is a slight possibillity because the suns gravity could pull it closer to earth, but we should be more worried about other galaxies colliding with ours. that is a big posibillity.
Actually, most galaxies are all moving away from all other galaxies, not just from ours. The exception is the Andromeda galaxy, with which the Milky Way is on a collision course.
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
yea, we havent been there but look up the pictures from the hubble telescope and it will show you the different types and more=======================================Millions of other galaxies outside of ours have been photographed.Each one of them is composed of millions of stars.
It is difficult to accurately measure the distances to other stars in our own galaxy, not to mention the distances to other galaxies. The Milky Way galaxy, of which our solar system is a tiny part, is a little bigger than the average, but not greatly so. The nearest other galaxies to ours are the Large Magellanic Cloud and the Small Magellanic Cloud, which are dwarf satellite galaxies of the Milky Way.
Because galaxies don't expand. The universe expands. Think of galaxies as little spots on a balloon. When you blow it up the surface gets larger not the little spots, but the spots do get further apart. Gravity creates the extreme flatness that you observe. Moments after the big bang the initial structure of the universe was set, that applies to the size of the galaxies as well. The only observable difference is the galaxies were a lot closer to each other in the beginning. Gravity then took over and started effecting the closest galaxies by pulling them closer together. The galaxies face a battle between the expanding universe and the gravity of other galaxies.
There are billions of other galaxies; perhaps 100 billion or so (1011) in the observable Universe. Some of the closer ones - that can be seen with the naked eye - are M31 (a.k.a. the "Andromeda Galaxy", the Large Magellanic Cloud, and the Small Magellanic Cloud.
