The Andromeda Galaxy, M82, Bode's Galaxy
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.
Some galaxies are bound together gravitationally into what is called Local Groups. Because of the gravitational attraction between them they are approaching each other.
Galaxies are generally a collection of stars. But within any galaxy, there are lots of other objects, including planets. So galaxies are related to planets in some ways.
After the Milky Way galaxy, there are many other galaxies in the universe. Some of the closest galaxies to us are the Andromeda galaxy and the Triangulum galaxy. Beyond these, there are billions of other galaxies in the universe, each containing billions of stars.
The general tendency is for galaxies to move away from each other, in other words, the Universe is expanding. Only in our "immediate neighborhood" will you also find some galaxies that move towards us.
spiral, barred spiral, elliptical, irregular, and peculiar
Yes, they are usually of a similar size range to other types of galaxies, from a few thousand lightyears across to a million or more. Their formation is often as a result of two or more galaxies colliding, or coming close to each other.
there is only 1 universe and their is billions of galaxies in it !
None. Galaxies on the other hand do contain planets
There are billions of galaxies in the Universe.
spiral,elliptical,irregular galaxies
Yes. Scientists haven't been able to explore other galaxies. I believe that there is life in other galaxies just like Earth. but how do they explore galaxies? i mean how do they know there are other galaxies? do they have any proof of lik=fe on other galaxies? ^^^^^^^
