Looks like Jupiters Cloud Formatons are changing rapidly and very noticable. Maybe Iceman or somebody could compare pictures from recent and a few months ago.
Jupiter's obviously about to turn into a star. It was predicted in Arthur C. Clark's 2010 - Odyssey 2.
"The Leonov crew make a hasty exit from Jupiter, observing as the swarm of monoliths spread to engulf Jupiter. Through a mechanism the novel only partially explains, these monoliths increase Jupiter's density until the planet achieves nuclear fusion, becoming a small star. In the novel, this obliterates the primitive life-forms which had inhabited the Jovian atmosphere, which the Monoliths' controllers had deemed less worthy than the aquatic life of Europa."
I believe Coronado are planning to produce a high-magnification version of the PST for future Jupiter observations.
