Our neighbouring planet Venus is gaining popularity in the terrestrial planetary sciences, especially since the selection of three new Venus missions by NASA and ESA in 2021. Now, for the first time ever, scientists have directly observed surface changes that indicate active volcanism on Venus. This discovery was made with data from NASA’s 30-year-old Magellan mission and is only a small preview f ...[Read More]

The Moon is our nearest neighbour but despite its proximity to Earth its two faces are still veiled in mystery! This week PhD student Alice Turner from the University of Oxford explores deep lunar seismicity and what this can (or cannot!) tell us about the Moon’s interior and its near- & far-sides! Outlining the Earth and its Moon with seismicity    Mapping out the locations of earthquak ...[Read More]

Sliding across the Solar System – The missing origins of gigantic landslides

Landslides can be impressively huge and fast and can occur on all sorts of places including asteroids, rocky moons and Mars! Giulia Magnarini Post Doctoral Researcher at the Natural History Museum in London writes all about these gigantic landslides and the clues they could hold into the martian past! Gigantic landslides are ubiquitous in our solar system. Indeed, Earth, Mars, Mercury, Venus, aste ...[Read More]
