Extend your arm with a quarter between your thumb and index. That's the moon.

Now take a coaster in your hand. That's our earth as seen from the moon.

It would be pretty cool to be a moon orbiting Jupiter
Oh, I interpreted this headline slightly differently--I was expecting to see a set of epicycle-orbit-diagrams given the Moon as the center of the Solar system.
This is neat to see, though I'll admit I was hoping to see broader views of what the sky would look like if, say, Jupiter or Saturn were that close to us.

If you're interested in a direct size comparison like this, I've recently made a poster for our campus planetarium that shows all the planets at once. It's CC licensed, so you're welcome to print your own copy:

I've recently bought my first telescope, a 6" reflector. I'm glad I bought it instead of a new iPad or Retina MacBook.

I fear that with the current urbanization trends, in the near future most people will never live to see a dark night sky.

Considering that astronomy played a huge role in early human history and civilization, I think we're losing a huge part of the human experience.
