Io’s internal heat is generated by Jupiter-driven tidal dissipation and Laplace resonance. This energy partially melts the mantle, but the melt fraction, depth, and spatial distribution of dissipation remain poorly […]

Ancient Rocks Reveal Themselves As Carbon Sponges
Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.

Eruption Column Modelling Of Explosive Volcanism On Venus
Volcanism on Venus has never been directly observed, but several measurements indicate present-day activity. Volcanism could potentially play a role in climatic processes on Venus, especially in the sulfur cycle […]

New Fossil Discovery Reveals How Volcanic Deposits Can Preserve The Microscopic Details Of Animal Tissues
An analysis of a 30,000-year-old fossil vulture from Central Italy has revealed for the first time that volcanic rock can preserve microscopic details in feathers – the first ever record […]

How Io Became The Most Volcanic Body In Our Solar System
Scientists with NASA’s Juno mission to Jupiter have discovered that the volcanoes on Jupiter’s moon Io are each likely powered by their own chamber of roiling hot magma rather than […]

Chemical Evolution Of An Evaporating Lava Pool
Many known rocky exoplanets are so highly irradiated that their dayside surfaces are molten, and `silicate atmospheres’, composed of rock-forming elements, are generated above these lava pools.

Volcano World Survey: Observations Of Loki Patera By Juno During Close Flybys
We used data from the Juno spacecraft to investigate both the spatial and temporal properties of Loki Patera on Io, acquired in two infrared bands between December 2022 and April […]
