This may be a silly question, since I know very little about space and physics. On the galaxy map, it shows the Milky Way, lots of galaxies in the distance, and in between is presumably dark space. There are lots of little lights in between - what are these?
Are they stars? I thought that those had to exist within a galaxy.
If they are stars, would they have planets in orbit?
And if they do, why wouldn't the Reapers just harvest them instead?
I only know that in real astronomic photography, you do see other far away galaxies as points of light, just like stars. They are further away, hence even the massive galaxies are just visible as dots but they have enormous luminance so you can still see them. Only the closer ones (like Andromeda) can be resolved higher and look like shapes, not just dots.
Of course, how well you can resolve those distant light sources depends on your equipment.
Is that what you meant?
They very well could be other stars, they don't have to exist in galaxies. Galaxies form as black holes pull every material nearby into themselves.
The thing you are refering to is a rogue star, and according to a recent study, there might be quite a lot of them: http://news.sciencem...y-be-everywhere
Stars can exist in the void between galaxies. Also, very distant galaxies will appear as small dots similar to a single star. When Hubble was launched they pointed it to what was assumed to be a single star. It was in fact a distant galaxy made up of some 200-300 billion stars.
Getting slightly off topic here, but how do we really know that the Milky Way really looks like how we envision it? We've observed other galaxies and made deductions based on data collected from observing surrounding systems, but no one really knows what our own home galaxy looks like.
It would be funny if we finally got a clear view of our galaxy and it looked nothing like how we pictured it.

We didn't envision it, we actually visioned the Milky Way. A huge part of it is visible with the naked eye, but only from some regions of the planet. Then there are the images from telescopes, radio-telescopes, Hubble, Kepler. The rest is just mathematics and putting things together.

I believe it is based on data taken from inside our galaxy, like how far the objects (stars, planets, nebulae etc.) are from eachother and what is their relative postition compared to a fix point. Much like how the explorers of old mapped the surface of the Earth, when they had no means to leave the planet and observe it from up there.
The images you can see about the milky way are artistic representations based on the data we have.

These "light sources" are (dwarf) galaxies and nebulae. There are hundreds of billions of galaxies in the universe, just take a look at these models, it will give you an idea how freaking huge the universe is.
