A new survey using satellite imagery and ground penetrating radar has revealed signs of volcanic activity on Mars that is much more recent than previously thought. The study conducted over the Elysium Planitia plain suggests that volcanic activity has occurred within the last 120 million years, with some eruptions dating back just 1 million years ago. The discovery indicates that Mars might still be volcanically active and could potentially have large water ice deposits underground. The findings shed light on the planet's geologic and magmatic state, as well as its aqueous history.

A global study of Io's volcanic activity suggests that the moon's tidal heating is concentrated within its upper mantle. By analyzing data from sensors measuring heat emission, researchers found that the moon emits 60% more heat along its lower latitudes, indicating that the heat responsible for volcanic activity is located just below the surface. This suggests the possibility of a soft upper mantle or even a molten ocean beneath Io's crust.
