Venus' mysterious haze is actually cosmic dust

Scientists have created a physical model that suggests the mysterious haze on Venus is not caused by volcanic activity, but rather by iron dust and sulfuric acid particles suspended in the atmosphere. The model, developed by researchers from the University of California, Los Angeles (UCLA), and the California Institute of Technology (Caltech), simulates the interactions between these particles and the planet's atmosphere, and shows that they can create the same properties as the observed haze. The study's findings challenge previous theories that attributed the haze to volcanic activity, and provide new insights into the chemistry of Venus' atmosphere.
