The four Galilean Moons are pretty big and bright, only not visible to the naked eye because Jupiter outshines them. You can probably see them with some binoculars and a good night sky.
I was just watching a quizshow on TV, and they had almost the exact same question, with Megadeath and Mötley Crew (sic) being two of the options (strange coincidence). The other two, however, were Limp Biscuit and Avenged Sevenfold.
10/10, but not too fast. Took a long time thinking about the space one. And I was pretty sure Lynyrd Skynyrd was spelled correctly, but Megadeath was giving me pause.
9/10 because I thought the last one was a trick question about Galileo, like a little-known fact that people saw Uranus before Jupiter's moons. And I was looking at Jupiter last night and wishing I owned a telescope so I could see its darn moons!
I got it mostly because so many questions - or rather answers - about TPB have been posted on Jetpunk before. So much so that I now routinely guess this in film quizzes - it is likely to be one of the answers. :)
What got me was the movie thing
