The IAG #Planetary Gemorphology Image of the Month 📸 for August is now online! A team of researchers discusses the colourful and bright dusty halos that occur on Martian sand dunes in early spring. The halos are a good indicator of mass-wasting driven by the seasonal sublimation of CO2 ice! 🌕😇✨

The IAG #Planetary Gemorphology Image of the Month 📸 for May is now available. PhD candidate Marie Azevedo explains how the layers of different types of dusty ice deposits in Louth crater on #Mars tell us a story about the past. planetarygeomorphology.wordpress.com/2025/05/01/k...
The image shows a circular (white) water ice deposit in a crater on Mars, which is around 12 km in diameter. The surrounding area outside of the crater is yellow in colour. In the upper left corner of the circular ice deposit a darker patch (dark grey) is visible. This patch contains dunes. In lower right half of the ice deposit layers can be recognized by faint, slightly grey lines.

‪The IAG #Planetary Gemorphology Image of the Month 📸 for April is now available. Undergraduate student Kyleshaquill Fred Velez takes us to Enceladus, an icy moon of Saturn, where mass wasting occurs on the steep slopes along tectonic features.

A four panel image showing black and white photos of the surface of Enceladus. The surface of Enceladus is highly fractured and hosts a lot of craters. In the images, steep slopes around the geological structures are highlighted on which darker streaks are present.

The IAG #Planetary Gemorphology Image of the Month 📸 for February is now available. Dr. Määttänen, Dr. Tirsch and Dr. @jorgehb.bsky.social show us the wonderful variety in clouds on Mars ☁️🌤️🌪️ planetarygeomorphology.wordpress.com/2025/02/01/a...
Two images of clouds on Mars. Left image: clouds and dust at the Northern Polar Region of Mars during the local spring (HRSC image). Right image: clouds and dust at the Northern Polar Region of Mars during the local winter (VMC image). The left panel shows a textured spiral dust storm (brownish) mixed with water ice clouds (bright white) (indicated by arrows). The right panel shows the North Polar Hood, a large scale water ice cloud system.
