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.
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..
No, not all galaxies have planets. Planets are found within individual galaxies, such as our Milky Way galaxy, but there are many galaxies in the universe where planets may or may not exist.
Yes, actually there are trillions of other galaxies with stars, and planets in the universe.
The Milky Way is the name for our own galaxy, so your question is, are there planets in other galaxies? While our technology is nowhere near good enough to detect planets in other galaxies, I think it is certain that those planets do exist.
