Heiligenshein on Ryugu

Heiligenshein on Ryugu
Heiligenshein on Ryugu Greenler's 1980 classic "Rainbows, Haloes and Glories" is a must-read around our lab. I can remember being introduced to the book by my own PhD advisor, Peter Smith way back in 2003. It's still a useful and engaging tome, describing optical effects valid for atmospheres around any planet, and even some bodies without atmospheres! As for the photos above, they are annotated images of the Asteroid Ryugu, as Hyabusa 2 approaches, with arrows pointing to the area where Heiligenshein is observed. JAXA
