Satellite images can now reveal the remarkable biological coloration
of microbial hot springs in Yellowstone National Park. Examples are
shown here from the Lower/Midway Geyser Basins and Hayden Valley of
Yellowstone. The visible and near-infrared bands are combined to
show microbial pigmentation in these first-ever "true color" images
of Yellowstone thermal features from space.

Research is underway to combine this type of satellite imagery with
field measurements of active microbial hot springs and extinct
thermal features in Yellowstone, the latter of which could resemble
ancient mineralized hydro-thermal areas on the surface of Mars.
