100,000 years
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
A long time
At the speed of light, it takes millions of years. For example, the Andromeda galaxy, which is the closest galaxy to our Milky Way galaxy, is about 2.5 million light years away, that is, traveling at light speed it would take 2.5 million years to get there.
If you find a place where the sky is good and dark and you know where to look, you can see theAndromeda Galaxy in the night sky. It looks like a fuzzy patch of dim, hazy light. It's actually agalaxy of hundreds of billions of stars, completely outside of the Milky Way galaxy that we live in.The distance to the Andromeda Galaxy is usually given as a couple of million light years.That would be the answer to the above question.
The Milky Way's diameter is about 100,000 light-years.

About 100,000 years
our galaxy is called the Milky way. its approximately 100,000 light-years (9.5×1017 km) in diameter.
Uranus is within the Milky Way Galaxy.
Not long at all - as you/we are already in it. About 25,000 light years from the centre.
A long time
Mars (and every other planet in our solar system) is nowhere near the center of the galaxy. About 75,000 light years...
Between 100,000 and 180000 years.
Between 100,000 and 180000 years.
Jupiter is a planet in the milky way galaxy. Along with all of the other planets in the milky way galaxy, Jupiter has existed approximately 4.5 billion years.
The Milky Way is estimated to be about 2,000 light years thick, but about 100,000 light years long/far... Which i guess you can tell, thats a lot.
