Wall of acid clouds on Venus spanning 7,500 km went unnoticed for 35 years

Scientists from Japan's space agency JAXA have discovered a "giant" wall of acid clouds hiding below the cloud tops on Venus, swirling around at speeds similar to that of jet planes. This atmospheric disruption, which stretches up to 7,500 kilometres, went unnoticed for at least 35 years. Scientists said it's the first serious candidate for planetary-scale wave at low altitudes.
