Have you ever heard of Point Nemo?

At more than 1,000 miles from civilization, its considered the most remote location on Planet Earth... It lies between New Zealand and South America and is fittingly known as the spacecraft cemetery, as the United States, Russia, Japan, and Europe have used it to dump some 263 pieces of space debris since 1971.

Man-Made Pollution - Visible From Space!


NASA Satellite Spots Foul Pollution Over Shipping Lanes



Nitrogen dioxide is a nasty gas produced largely by internal-combustion engines. This pollutant is rampant throughout the planet, but nowhere moreso than above the heavily trafficked lanes of international shipping vessels.

Animated Maps of Water Vapor (Cloud Cover, etc.)


The ability to see Earth from space has forever changed our view of the planet. Now able to look at the Earth as a whole,. we can observe how its atmosphere, oceans, landmasses, and life interact as global systems

Water Vapor (Monitoring Moisture Patterns)

Heat and moisture from the oceans drive atmospheric circulation and weather patterns. Moisture in the atmosphere forms clouds which cover an average of 40% of the Earth at any given time. Clouds are carried through the atmosphere by the wind. The patterns in cloud motion in this time-lapse sequence show how Earth's winds move in bands or zones which define regional wind directions.
