Venus activity: atmospheric rings and geology

Overview

Recent research has highlighted two unexpected aspects of Venus. An early 2010 observation with the Extreme Polarimeter on the William Herschel Telescope detected faint concentric atmospheric rings visible only in polarized light, a phenomenon that has not yet been reproduced. In parallel, a study by ETH Zurich scientists, published in *Nature Geoscience*, presented high‑resolution simulations and radar analyses showing that Venus’s extensive rift valleys are still deforming, indicating ongoing mantle heat release, uplift rates of several centimeters per year, and the possibility of active volcanism. The later report reinforces the earlier findings, challenging the long‑standing view of Venus as a geologically dead world and suggesting a dynamic interior that may guide future missions and exoplanet research.
