Question

Your 14 year old child/sister/brother/niece/nephew/neighbor' kid, etc., came across this picture.

Awesome, isn't it?

It is an artwork, not a real picture, although it uses pictures of real objects. It was produced almost two decades ago as part of a public outreach campaign for one large NASA program. That project is now gone, but this illustration stayed.  It is very famous, one can find it all over the Internet.

Your kid is fascinated by it and knows that once upon a time you took a GE astronomy course.

So he or she asks you: "What do I see here?"

What do you say?
