For the most part, we can't see individual stars in other galaxies (with one notable exception), so obviously detecting planets is out of the question.
(The exception is supernovae, stars that are in the process of exploding.)
None. Galaxies on the other hand do contain planets
yes we can live
Very probably
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.
There are many other planets in many other galaxies.
There's nothing between the galaxies. It's just other galaxies that float around the universe.
Probably, though most planets discovered so far - or perhaps all of them - are in our own galaxy. The reason for this is simply that it is easier to discover planets when they are relatively close to us. But, having discovered about a thousand planets nearby, there is no particular reason to believe that other galaxies would be devoid of galaxies. After all, the same laws of physics work in other galaxies as here.
It is possible that every galaxy has some planets. We just are starting to detect some planets in other galaxies.
We don't have the means to detect or observe planets in other galaxies. But so many hundreds of them have been discovered in our own galaxy that it's a safe bet that other galaxies must have them too, in abundance.
no fairies don't exist any where..
Well, we don't know whats all out there because it's hard to get into other galaxies, but we think its the only one with planets. (We don't know for sure so do some more research)
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
