October 2026 Satellite Puzzler

NASA Earth Observatory's October 2026 Satellite Puzzler is a monthly feature built around a puzzling satellite image. The challenge is to identify the location shown in the image and share what clues you see, where you think it is, and what makes that place interesting or unique to you.

To answer, readers submit their response using the provided form and select “Puzzler Answer” as the topic, including a preferred name or alias. A simple location guess is acceptable, but those who want to impress can also identify the satellite and instrument that captured the image, the spectral bands used, or a subtle detail about the area's geology or history. Readers are also encouraged to share anything that catches their eye, or if the location is their home or means something to them.

The prize is not money or a trip to space, but puzzler bragging rights. About a week after the challenge, the answer will be posted at the top of the page along with a link to an Earth Observatory Image of the Day story explaining the image in more detail. NASA will recognize the first person who correctly guesses the location and may also highlight readers who share especially thoughtful or interesting answers.

By submitting a response, participants acknowledge that their comments may be edited, excerpted, and published on the page. Until the reveal, readers are encouraged to zoom in, look closely, and enjoy the challenge.
