It took 35 days on an SGI Origin single processor. The colours indicate density going from blue through green and yellow to red at higher densities. There are 4 major clusters and 13 smaller clusters providing the contraints that define this region. The background is a pseudo-ray traced image of a Lyman alpha simulation. Higher Brightness and opacity indicate higher density.
Colours indicate temperature.
Red is 4,000,000K, Blue is 10,000K and purples represent intermediate temperatures. Note that the cores of the knots are cool and thus blue. Through the red hot gas around them they appear purple.
