Satellite tracks Saharan dust to Amazon in 3D

For the first time, a NASA satellite has quantified in three dimensions how much dust makes the trans-Atlantic journey from the Sahara Desert to the Amazon rainforest. Among this dust is phosphorus, an essential nutrient that acts like a fertilizer, which the Amazon dep

'Weather Bomb' - Explosive cyclogenesis in the Atlantic

A low pressure system underwent what is known as "explosive cyclogenesis" - or less formally became a "weather bomb" - when it intensified rapidly with a steep decline in pressure, between Greenland and Iceland late on Monday and early on Tuesday. Th

Tracking one of the most destructive Atlantic hurricanes in history

Hurricane "Hugo" (1989) was a classic Cape Verde-type hurricane first detected as a tropical wave emerging from the coast of Africa on September 9, 1989. Moving steadily westward, the system became a tropical depression the next day, a tropical storm on the 11

Seeing photosynthesis from space

Scientists have discovered a new way to use satellites to measure what's occurring inside Earth's land plants at a cellular level. During photosynthesis, plants emit what is called fluorescence -- a form of light invisible to the naked eye but detectable by
