Puerto Rico Went From No Drought to Extreme Drought in Just Months

11 September 2026 at 00:17
Puerto Rico Drought 2026Puerto Rico went from no drought to widespread extreme drought in just months as rainfall collapsed and water shortages spread. Puerto Rico usually enters its wet season in May. In 2026, however, the expected rains largely failed to arrive through late August, leaving much of the U.S. territory in drought. The prolonged dry spell has [...]

New Mexico’s Largest Reservoir Was Nearly Full. Now It’s at 1.4%

Elephant Butte Reservoir Runs LowNew Mexico’s largest reservoir plunged to just 1.4 percent capacity in July 2026, revealing the dramatic impact of prolonged drought and record early snowmelt. NASA is using satellite data to help water managers understand the shrinking supply and prepare for future shortages. When astronaut John Glenn remarked on the landscape below him while orbiting Earth [...]

June 2026 Satellite Puzzler

9 June 2026 at 16:51
A series of tan parallel ridges runs from left to right, with green areas and small lakes filling the low-lying spaces in between.

Every month, NASA Earth Observatory features a puzzling satellite image. The June 2026 puzzler appears above. 

Your Challenge
I
dentify the location shown in this satellite image. Share what clues you see, where you think it is, and what makes this place interesting or unique to you.

How to Answer
Submit your response using this form and select “Puzzler Answer” as the topic. Please include your preferred name or alias.

You can keep it simple and just guess the location. Want to impress us? Tell us which satellite and instrument captured the image, which spectral bands were used, or point out a subtle detail about the geology or history of the area. If something catches your eye, or if this is your home or means something to you, we’d love to hear about it.

The Prize
We can’t offer prize money or a trip to space to see Earth like satellites and astronauts do. But we can offer something almost as rewarding: puzzler bragging rights.

About a week after the challenge, we’ll post the answer at the top of this page, along with a link to an Earth Observatory Image of the Day story that explains the image in more detail. We’ll recognize the first person who correctly guesses the location, and we may also highlight readers who share especially thoughtful or interesting answers. By submitting a response, you acknowledge that your comments may be edited, excerpted, and published on this page.

Until then, zoom in, look closely, and enjoy the challenge. See you at the reveal!

Super Typhoon Sinlaku Was So Powerful It Made the Sky Ripple With Gravity Waves

Super Typhoon Sinlaku Atmospheric Gravity WavesA rapidly intensifying super typhoon sent giant atmospheric ripples skyward, revealing a hidden connection between extreme weather and near-space. In April 2026, Super Typhoon Sinlaku swept across the North Pacific, bringing torrential rain and flooding to parts of the Mariana Islands. The storm intensified into a “violent typhoon,” the highest category used by the Japan [...]
