In this video, Chad, our technical artist, demos his recent work on shaders which simulate atmospheric scattering (in real-time, of course).

Atmospheric scattering is a process in which particles in a planet’s atmosphere scatter sunlight. It is the reason why the sky is blue, and why the setting sun is red.

Please note: This video is a demo created by Chad; it is not from Universe Sandbox ². Atmospheric scattering is an experimental feature still in its early stages. Do not expect to see this implemented in an alpha release anytime too soon.
