It snowed on December 19 in the Sahara Desert, and NASA's Landsat 7 satellite was there (or rather, hundreds of miles overhead) to see it.

The photo comes from Landsat 7's Enhanced Thematic Mapper Plus visible-light camera, and depicts the first snowfall recorded in the massive African desert in 37 years.

The snow-covered area depicted in the photo lies on the northern end of the desert, near the Moroccan-Algerian border and the town of Aïn Séfra. Here's the full image, which you can click to enlarge:

Photographer Karim Boucheta was in the right place at the right time to capture photos of the Saharan snowfall from the ground, and he's posted them to Facebook:
