Waving your hand near the large moving sun reveals intricate moving structures on and above the solar surface. The base image is of the sun at 80,000 degrees, and when you hold your hand near the sun, the 1,000,000 degree image is revealed, both images moving in sync. (The screen is interactive from both sides, hence the reversed legends.)
The imagery is from the Solar Dynamics Observatory (sdo.gsfc.nasa.gov), which updates with a new still image every 15 minutes in a variety of wavelengths. The installation displays a moving animation of the data from the previous five days, up to the last 15 minute image.
This early version is using the 1K (1024x1024) SDO data, the updated version uses the 2K and 4K datasets for greater visual clarity, and offers selection of wavelengths to view.
