Here’s your ‘Earthbound Country Bumpkin Stupid Question of the Day’:

How do they tell/measure distances in space? How do they know how far apart things are, as in this picture saying star Rigel and Witch Head Nebula are far BEYOND the comet?

Also, have they taken pictures of our WHOLE Solar System? If not, how do they truly know where everything is? Can Hubble get far enough ‘out there’ to take a picture of our WHOLE solar system? I’ve seen pictures of our Galaxy, and others - but are they for real or just a rendering based on guesses?

I looked here, but these are individual photos that they cropped together to show the outer planets. It’s a pretty cool site, actually.
