Crab Nebula
A stereo pair of the Crab
A volume rendering of the Crab Nebula. The data consisted of infrared images of the nebula at 27 different wavelengths. The different wavelengths correspond to different red-shifts of the light from the nebula, and, because the nebula is an expanding shell of gas, the red-shift of an area is proportional to its distance to Earth. Thus (in theory), this volume rendering of the data cube shows what the nebula looks like in three dimensions. This work was done for Sally Heap and Bruce Woodgate of Code 681, NASA/GSFC.

Evolution model
A volume rendering of a results of a model of species evolution; the model was created by Jack Corliss on Goddard's MasPar MP-1. The model consists of a two dimensional characteristic space with a certain population at each point in the space. At first, there is a single dense population at the center of the characteristic space; as time progresses, the population mutates, thus spreading through the space. The rendering uses time as the vertical axis - each 2D horizontal slice is a single time step of the model; color and opacity represent population density. The result is a "family tree", showing the evolution of multiple distinct species from the initial population.

Puzzle Earth
An image of the Earth as an exploding jigsaw puzzle. This is a high-res rendering of one frame from the "Puzzle Earth" animation, which is included on the Animations page.

Cloudy Earth
A transparent, cloudy Earth, from the "Cloud Science" section of the EOS video "Earth: A New Perspective".
