Here's a fun video: the sixth flypast of Jupiter by NASA's Juno spacecraft, which it completed last month. I don't know why someone decided to include a creepy soundtrack with the video; it's more than compelling enough without it! Oh, well - you can always mute the volume. Watch it in full-screen mode for best results.
It's hard to imagine that there are no solid features at all in what we've just seen. Jupiter is a so-called 'gas giant' planet, so its entire surface is just a swirling mass of gas (you should pardon the expression), no matter how solid it may appear to our eyes.
