34 dust devils on Mars in 1 shot!
Mars is famous for its tornado-like whirlwinds, made of the dusty debris coating its surface. These are dust devils. They form the same way on Mars as they do on Earth: as the sun warms the ground, the ground then heats the thin layer of air above. Then that air rises quickly through the cooler, dense air above, spiraling around a small area of low pressure.
On June 17, 2026, ESA shared an image from its Mars Express orbiter of 34 dust devils it captured on the red planet’s surface back on December 7, 2024. Can you spot all the dust devils in the image above?
Look closely. This region of Mars is in a valley system known as Mamers Valles. It holds ridges and plateau-like areas along with many small craters. Although the dust devils may look tiny – as a small light-colored dot with a shadow – in reality, dust devils on Mars can grow even larger than those on Earth. Martian dust devils can tower up to 5 miles (8 km) high and span hundreds of yards wide.
The location of the dust devils is in the image at the bottom of this post.
Then check out the original here. The largest version shows a whopping 34 dust devils!

More on Mamers Valles
Mamers Valles lies in Mars’ northern hemisphere. It consists of of valleys and canyons, some of which stretch for more than 600 miles (1,000 km). The higher areas are mesas, cliffs and some debris-covered glaciers. The glaciers lie at the base of the steep slopes. The terrain shows evidence that it was carved by flowing materials, such as water, ice and lava, sometime in its past.

Bottom line: The Mars Express orbiter caught this view of the red planet, which is peppered with whirlwinds. Can you spot 34 dust devils in this one shot of Mars?
