Re: Moons of all the planets in our solar system
#2There is a comment on the site that the Galilean Moons of Jupiter can be seen with the naked eye under dark skies. I've known people who might have eyes good enough to do that, but for the rest of us even a modest pair of binoculars is enough. To me, it's one of the funnest things you can view in the northern hemisphere without getting out more serious equipment. (Another would be the Orion nebula. If you can set the exposure on your camera, you can even photograph it, although without tracking it'll be blurry.)

The wikipedia page has an "amateur" photo of the Orion Nebula that highlights your claim, it's pretty glorious.

That is one beautiful sight: https://en.wikipedia.org/wiki/Orion_Nebula#Image_gallery

you could use fixed tripod with 500/focal-lenght rule then stack with DeepSkyStacker.

Note that this photo is not how it would look without a telescope or very good telephoto lens (with tracking), but it will still be visible

#6I'm surprised we haven't seen more hard sci-fi in the jovian or cronian systems. While constant 1g acceleration drives open the whole solar system to the ~month travel time that benefits stories, much more realistic accelerations (or limited fuel) can still manage the same within those systems. Add to that the plethora of interesting moons, rings, and gravitational points to focus people and material around and the action should flow quite naturally.
See The Expanse Season 2 (it's amazing).

The Galilean moons are hard to see with the naked eye because the light from Jupiter is overwhelming. It is much easier if you use a distant object like a lightpost to just barely block out Jupiter.

Wasn't Galileo first to observe them with his telescope or were they mentioned somewhere before? I assume back then the skies were darker and people probably had better eyes so if they are observable I would assume somebody would have mentioned them.

#9If you want to play with this data, it's available in various formats [1]
I happened to use this last week because we needed test data for a community tree in an app we're building. There are nine communities, and we needed test cases with 0, 1, and many subcommunities. This not only provided ready test cases, but the team is learning celestial facts while working on the feature!

There are a few confounding factors:
1. Jupiter is very bright.
2. The moons aren't always visible (they're behind or crossing Jupiter).
3. The magnitude of the moons changes with the relative positions of Earth and Jupiter.
It's possible that Galileo was not the first to see them, but if you don't know what they are or how you managed to see them, you're probably not going to be able to get anyone else to believe you. The telescope allowed Galileo to track their movement and also to convince others, who could also look through a telescope and see them easily.
