Giant polarized rings in Venus’s atmosphere: an accidental 2010 observation may finally have an explanation A team led by Gourav Mahapatra (Delft University of Technology) has published a peculiar 2010 observation of vast concentric polarization rings on Venus, captured by the experimental ExPo polarimeter on the William Herschel Telescope during a chance 36-minute session. Their radiative transfer models suggest the rings are the polarization signature of atmospheric gravity waves — a mechanism potentially linked to Venus's atmospheric superrotation.... https://skycr.org/2026/07/28/venus-atmosphere-polarization-rings/

Polarimetry is the measurement and interpretation of the polarization of transverse waves, most notably electromagnetic waves, such as radio or light waves. Typically polarimetry is done on electromagnetic waves that have traveled through or have been reflected, refracted or diffracted by some material in order to characterize that object. Plane polarized light: According to the wave theory of light, an ordinary ray of light is considered to be vibrating in all planes of right angles to the direction of its propagation. If this ordinary ray of light is passed through a nicol prism, the emergent ray has its vibration only in one plane.

An article published in the journal "Nature Astronomy" describes unprecedented observations of matter around a black hole. A team of researchers used the data detected using an X-ray polarimeter on board the PoGO+ satellite to obtain information on the part of hard X-rays that are reflected from the accretion disk around the black hole of the Cygnus X-1 system and identify the shape of the matter that composes it.

Few challenges for X-ray Polarimetry

"The %ee has not yet been determined because we don't have access to a chiral HPLC and nobody in their right mind uses a polarimeter in serious publications"
