Venus atmosphere haze caused by iron dust and sulfuric acid
Scientists propose that cosmic dust made of iron and sulfuric acid creates the thick haze around Venus.
New physical model explains haze
A recent study suggests that a specific mixture of materials accounts for the planet's unique appearance. Researchers found that iron dust combined with sulfuric acid matches observed atmospheric properties. This combination replaces previous theories about the composition of the upper cloud layers.
Model matches observational data
The proposed physical model successfully reproduces the light scattering seen by spacecraft instruments. Independent analysis confirms that these ingredients generate the correct optical depth for the haze. The findings align with measurements taken from multiple missions over several decades.
