Each month, Earth Observatory offers up a puzzling satellite image here on Earth Matters. The November 2013 puzzler is above. Your challenge is to use the comments section to tell us what part of the world we are looking at, when the image was acquired, and why the scene is interesting. How to answer. Your […]
Agony in the Philippines Satellite images of Super Typhoon approaching and smashing into the Philippines last week were extremely worrisome.

Following their successful “Let It Snow” photo contest, our colleagues at the soon-to-launch Global Precipitation Measurement (GPM) mission are looking for your best photos and videos of rain, sleet, hail, snow and any other precipitation. They describe their “Unique Perspectives” contest this way: There are many ways to view precipitation…We’d like to see weather from […]
Hindus are celebrating Diwali this week. That means cities and towns around the world—but particularly in South Asia—are ablaze with lamps, candles, and firecrackers. It’s also become a tradition (of sorts) to share a colorful image via social media that was supposedly taken by a satellite during Diwali. If that image turns up on your […]
Congratulations to Jaimen W. for solving the October Puzzler the fastest. The answer is Chile’s Lluta River. See the Image of the Day that we published on November 1, 2013, for details about the area. Phil Echelman was right on Jaimen’s heels, responding with the correct answer just two minutes after Jaimen. Congratulations also […]

In the dark, early hours of October 30, 2012, the VIIRS instrument on the Suomi NPP satellite caught this glimpse […]

Fourteen years ago, the Enhanced Thematic Mapper Plus on Landsat 7 acquired these images of mud trails off the coast of Louisiana. They were caused by bottom trawling in the Gulf of Mexico, a fishing technique that involves dragging large nets across the sea floor. Bottom trawling is an efficient way to scoop up shrimp […]
Since its launch in February 2013, Landsat 8 has collected about 400 scenes of the Earth’s surface per day. Each of these scenes covers an area of about 185 by 185 kilometers (115 by 115 miles)—34,200 square km (13,200 square miles)—for a total of 13,690,000 square km (5,290,000 square miles) per day. An area about […]
