Space Opera Fans discussion

Hello everyone i was wondering something as some of you know (My "novice" topic https://www.goodreads.com/topic/show/... am kinda new to reading/listning books and Im noticing a pattern in some book and this is the question about it

Do almost all "space opera/Science fiction" use some of the same places ? in particular almost all of the book I read are out of Earth but if for some reason they "must" return to Earth almost always use the moon EUROPA? for a place reference or just a "history" of it, why is that?

Keep in mind im not a American or well verse in geography/astrology but is there a reason for it...?

This is more of a curiosity but I remember but not right now some other ones.

It has water. Will very likely be colonized.

I always remember the movie 2010 where they find chlorophyll...

Most rocky worlds in the Solar System do. It seems to me more like lazy writing (Arthur C Clarke excepted, of course...). It's more likely that humans will avoid a manned landing to prevent contaminating any traces of native life. The Cassini probe is being deliberately crashed into Saturn's atmosphere for the same reason.
