For scale, the Great Red Spot is over twice the size of the Earth.
See, it just never looks like that through my backyard telescope. That's why I sold the mother scratcher in a garage sale.
Bet if you built one of these babies you'd get some pretty awesome views of Jupiter.
Just noticed something not right in that video: the inside moon appears to be orbiting at a slower speed than the outside moon. Should be the other way around.
And I think they mean Juno, not Cassini.
Cassini passed close by Jupiter on the way to Saturn for the ol' gravity assist manuver.
Every video I can find on YouTube of Jupiter from Juno has involved a polar orbit, whereas this seems to have been shot from an equatorial pass, which is what one would expect from Cassini doing a flyby.
I think it's a trick of the perspective. The moons are at similar points in their orbits, and the probe is passing by them. Their "movement" is really just the changing perspective of the probe.
Hmm. I thought of that, but it would mean Cassini was moving retrograde to the planet's spin and the orbits of the moons. Possible, but it doesn't seem like the best way to do a grav-assist. Either that, or the camera is inverted in the picture, and 'up' is looking towards Jupiter's 'south pole.'
I noticed that as well.
