The natural world. Looking pretty for 3.5b years.

Khumbu IR

infrared photography sees more features than the human eye

Human eyes see objects in visible light only. We can't observe anything in ultra-violet (UV) or infrared (IR) wavelengths that cover a wider area of electromagnetic spectrum. These two light sources can show amazing details when photographs are produced using them.

Cameras on NASA's Terra satellite have produced impressive details while viewing the Khumbu region of Nepal and the glaciers near Mount Everest.

The Khumbu photographed in IR shows distinct detail of the glaciers covered in rocks, dust, and other debris in heat-trapping red colors. Likewise, near, shortwave, and thermal infrared provide additional regional information.

Such maps provide powerful insight on the impacts of the debris on glacial dynamics such as ice movement and melting. The IR photographs are also stunning and could nicely appear on any modern art gallery installation by themselves.
