I can spend hours on YouTube, just watching videos like this: Falling into Saturn (Simulation). It’s really cool to imagine what it would be like to fall onto a specific planet. Seeing the rings up close, seeing how things are, anyway… I’ve been watching these things for a long time and only today I found out that this is something you can do yourself, on your PC. Just grab it on Steam: Download - SpaceEngine
You can even see what other people discover by accessing their forum. There are various images of discoveries that people post there. Here are some examples: SE Object Extremes - Page 20 - SpaceEngine
The bad news is that in 24 days their forum will no longer exist. I didn’t quite understand why 
But there it is, I’m very happy to have found this.
