Mars’ “Young” Volcanoes Were More Complex Than Scientists Once Thought
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of […]

Magma Ocean Interactions Can Explain JWST Observations Of The sub-Neptune TOI-270 d
Sub-Neptunes with substantial atmospheres may possess magma oceans in contact with the overlying gas, with chemical interactions between the atmosphere and magma playing an important role in shaping atmospheric composition.

Silane-Methane Competition in Sub-Neptune Atmospheres As A Diagnostic Of Metallicity And Magma Oceans
The James Webb Space Telescope is characterising the atmospheres of sub-Neptunes. The presence of magma oceans on sub-Neptunes is expected to strongly alter the chemistry of their envelopes (100 bar-100 […]

Lava World Recon: Possible Tectonic Activity On Venus
Using archival data from the mission, launched in 1989, researchers have uncovered new evidence that tectonic activity may be deforming the planet’s surface.

Giant Pit Craters On The Seafloor Above Magma-induced Hydrothermal Vent Complexes
Massive injection of 13C depleted carbon to the ocean and atmosphere coincided with major environmental upheaval multiple times in the geological record. For several events, the source of carbon has […]

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.

Carbon Dioxide Release From Magma Deep Beneath Ancient Volcanoes Was A Hidden Driver Of Earth’s Past Climate
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the […]

Extreme Weather Variability on Hot Rocky Exoplanet 55 Cancri e Explained by Magma Temperature-Cloud Feedback
Observations of the ultra-short period rocky exoplanet 55 Cancri e (55 Cnc e) indicate that the planet’s dayside infrared radiation fluctuates by a factor of at least six on sub-weekly […]

LavAtmos 2.0: Incorporating Volatiles Species in Vaporization Models
Due to strong irradiation, hot rocky exoplanets are able to sustain lava oceans. Direct interaction between these oceans and overlying atmospheres can provide insight into planetary interiors.
