I suppose you might say that the main reason is they're incredibly far away! We haven't even gotten to other planets yet, and you're wondering about galaxies? The nearest other galaxies are so far away it takes even light 150,000 years to get there!
space ships. some people think that wormholes can lead to other galaxies
maybe but i think not
Not with present human technologies.
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.
NASA does not research other galaxies because they are too far away to travel to in a lifetime.
Not in the near future. Other galaxies are hundreds of thousands, or millions, of light-years away; travelling at the speed of light, it would thus take millions of years to travel to most galaxies; travelling at a lower speed would, of course, take longer.Not in the near future.

there is only 1 universe and their is billions of galaxies in it !
There are billions of galaxies in the Universe.
spiral,elliptical,irregular galaxies
None. Galaxies on the other hand do contain planets
I assume for the same reasons that our civilization wants to travel through outerspace, visit other galaxies and explore planets.
There's nothing between the galaxies. It's just other galaxies that float around the universe.
