Maybe one day - but not in our lifetime.
Galaxies do occur IN Solar systems. Galaxies are much much bigger than solar systems. This means that solar systems are found in Galaxies. The Galaxy we live in is called the "Milky Way Galaxy". The Milky Way is a barred spiral galaxy 100,000-120,000 light-years in diameter containing 200-400 billion stars. Each star is potentially a solar system like our own. NOTE: we can see that outside the Milky Way there are hundreds of billions of other 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? ^^^^^^^
Around 750 million years after the big bang. The oldest galaxy known is IOK-1 [See related link]

We are in the solar system, so any where we look (except in the starry night sky, which you could see other galaxies), we can find the solar system.
Our solar system is pretty small. There are hundreds of thousands of other solar systems with stars in them. That is what you see.
Stars, star clusters, distant galaxies, galaxy clusters, nebulae, ...
No
Yes, the solar system is the only one in our solar system. there are other solar systems many trillions of miles away. You can see their suns, these are the stars.
There are on the order of 100,000,000,000 (one hundred billion) galaxies in the universe, as far as current telescopes can detect. Some of these galaxies may hold up to 100,000,000,000 stars, but most galaxies probably contain at least 10,000,000,000 stars. Young galaxies under 2,000,000,000 years old may not have formed many solar systems yet, while very old galaxies more than 10,000,000,000 years old may have very few galaxies left. For the galaxies of middle age, as many as 1/4 of the stars may possess solar systems. My comment: While the answer above is true based upon current knowledge, it is essentially incorrect. The answer to your question is: ONE. Our Sun is named Sol - and the system of planets and other objects orbiting it are referred is referred to as "Solar", being of Sol. So other planetary systems exist, but they are not "Solar"... Comment: The above is incorrect, the answer above is for our known universe not the entire universe. There may be even more. The universe doesn't have a known edge, or a wall so, it's really hard to say. It would be possible to even say infinite, though scientists really hate the word infinite ;)
There are lots of spiral galaxies, so you shouldn't speak about the spiral galaxy as if there were only one, and while there are lots of moons inside galaxies, you may be thinking of galaxies that have other galaxies which orbit them; our own galaxy, the Milky Way, has the Greater and Lesser Magellanic Clouds as satellite galaxies, which perhaps is what you had in mind. A satellite galaxy is not a moon, however.
Yes, other galaxies have solar systems similar to our own Milky Way galaxy. These systems consist of stars like our Sun, planets, and other celestial bodies. Studying these systems helps scientists understand the diversity of planetary systems in the universe.
