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

Bright dusty halos around mass wasting on Martian Sand dunes Post contributed by Maria Kefa (master student), Dr. Susan Conway – LPG Nantes & Dr. Lonneke Roelofs – Utrecht University Mars’ winters are sufficiently cold that carbon dioxide (CO…

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! 🌕😇✨

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 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.
