Is Jupiter’s iconic Red Spot the same one that Cassini observed in the 1600s?

On top of that, the composition of the Spot seems value as well and that surprises me. We xcan look into the far distance realms of space and determined thr atmospheric compsition of a planet, even to the point to answer is there organic life there, but a planet in our own system and we can't stated "The Spot is composed of X, Y, Z atoms/molecules whatever".

The great Red Spot does indeed change color over time, varying from a dark brick read to a pale salmon pink (that is sometimes so pale it's hard to see it in an amateur telescope). And just as we don't completely understand show the spot formed and why it has been so persistent, we don't know what drives its color changes.

We still have a lot to learn about Jupiter!

The Jovians neglected to take out the extended warranty on their spot (despite many calls urging them to do so at a very reasonable rate) so had to save up for a century to buy a new one.
