Yes. Looking at a deeps space image it is apparent that the universe is filled with Galaxies. It is estimated that there are about 200 billion galaxies in the observable universe.
Yes.
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? ^^^^^^^
To know what is the life there, and if there's any other creatures or "aliens". some scientists are looking for planets with water and life on them.
We do not know. We have not made contact with any aliens.
We don't know - the closest galaxy to us is 2.2 million light years away.
There are many other planets in many other galaxies.
no fairies don't exist any where..
At least 3 or 4 galaxies can be seen with the naked eye. Other galaxies can be seen if you watch through a telescope. Basically, in any direction you look, there are galaxies.
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.
its just like applying for any other job
NASA sends research personnel there, but has not established a permanent base of any sort (there are several research stations that facilitate NASA and many other organizations' research).
Nobody knows but NASA might know in the future.
