The astronomers studying the atmosphere of Venus are facing a new mystery. The Venusian winds have been steadily accelerating for the last 6 years. Scientists monitoring the Venus Express orbiter since 2006 noted the stunning increase in the already super fast winds, from 186 mph to 249 mph. The astronomers acknowledge they do not understand why this enormous variation in wind speed occurred. What is it about the Venusian atmosphere that mainstream astronomers find so puzzling?
