Listening to Raindrops
Scientists have developed a new method to measure rainfall in the open ocean with underwater microphones. By measuring rainfall over the oceans the scientists will be able to improve global climate models.
Dissipation of Tidal Energy
The moon’s gravity imparts tremendous energy to the Earth, raising tides throughout the global oceans. What happens to all this energy? This question has been pondered by scientists for over 200 years, and has consequences ranging from the history of…
Argentina from MODIS
This Moderate-resolution Imaging Spectroradiometer (MODIS) image over Argentina was acquired on April 24, 2000, andwas produced using a combination of the sensor’s 250-m and 500-mresolution “true color” bands. This image was presented on June 13, 2000 as a giftto Argentinian…
First Infrared Images from GOES 11
These are the first test infrared images from the recentlylaunched GOES 11 satellite, taken June 10, 2000. TheGOES—Geostationary Operational Environmental Satellite—system observes weather 24 hours a day from two satellites orbitingabove fixed points off the east and west coasts of…
Earthquakes Strike Turkey, Indonesia
Two of the world’s most earthquake prone regions—Turkey and Indonesia—experienced damaging quakes in the first week of June 2000.The maps above show the location of the two quakes plotted on the Digital Tectonic Activity Map, a comprehensive database of fault…

Gross Primary Productivity
This map of plant photosynthesis was the first of its kind from the MODIS instrument, which was launched in December 1999 on the Terra spacecraft.
Black Holes Shed Light on Galaxy Formation
Astronomers are concluding that monstrous black holes weren’t simply born big but instead grew on a measured diet of gas and stars controlled by their host galaxies in the early formative years of the universe. These results, gleaned from a…
Feasting Black Hole Blows Bubbles
A monstrous black hole’s rude table manners include blowing huge bubbles of hot gas into space. At least, that’s the gustatory practice followed by the supermassive black hole residing in the hub of the nearby galaxy NGC 4438. These NASA…
