Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays, flaring up to become about a hundred times brighter in less than a minute, before returning to original X-ray levels after about an hour. This discovery may represent a new class of explosive events found in space.

Computer simulations explain Jupiter’s wild weather

30 November 2015 Astronomy Now

The numerous whirlwinds covering Jupiter are caused by upward gas flows originating deep within the giant planet. This is the conclusion reached by scientists at the University of Alberta (Canada) and the Max Planck Institute for Solar Research (MPS) in Germany after extensive computer simulations. Their models also explain why the Jovian whirlwinds’ direction of rotation is opposite to storms on Earth.
