SPECTACULAR and constantly changing cloud formations may be the norm on this turbulent gas giant. It”s suspected that one side of the planet is locked facing its sun (tidally locked), causing the planet”s atmosphere to become explosively superheated. As the roiling gases move toward the cool side of the planet, the gases sink and recirculate back to the hot side of the planet. The churning atmosphere may be in constant upheaval, the sound and fury never ending. Researchers at the Univ. of Texas at Austin McDonald Observatory reported that the planets in this binary star system have wildly offset orbital planes that might have been caused by its binary star partner Upsilon Andromedae B. Though the orbits of the binary pair are not known, if their orbits are eccentric, who knows what chaos this system might go through every eon or so.
