Fascinating paper by Ma+ on Temporal and chromatic variation of polarized scattered light in the outer disk of PDS 70 indicating that shadows are being cast by an (unseen) tilted inner disk, giving us more dynamical information on this system 🔭🪐 #astrodon

Images of polarized light taken at several differnt times and wavelengths. It looks like a cereal bowl with a red outer rim and blue inner circle, tilted to our line of sight. The illumination of the rings changes brightness between the different images.
