It's a phenomenon never seen before. Under normal conditions it doesn't even occur on Earth: the carving of gullies by CO2 ice blocks. Earth scientist @lonnekeroelofs.bsky.social proved that this may explain the formation of dune gullies on Mars www.uu.nl/en/news/myst... @astrobiologyou.bsky.social

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 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.
