Investigation Of Venus’ Thermal History, Crustal Evolution, And Core Dynamics With A Coupled Interior-lithosphere-atmosphere Model

by Keith Cowing

We simulate Venus’ evolution with a coupled one-dimensional solar-atmosphere-lithosphere-mantle-core model to predict currently unobservable features and its eruptive mass flux.

Analysis Of Io’s tidal Response As A Function Of The Properties Of The Partially Molten Layer

by Keith Cowing

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 […]

New Study Reveals Asynchronous Land–ocean Responses To Ancient Ocean Anoxia

by Keith Cowing

Earth experienced a period of intense, large-scale volcanism during the early Aptian. Around that time, it also experienced widespread ocean deoxygenation during the Oceanic Anoxic Event 1a (OAE1a) as well […]

Earth’s Largest Acidic Geyser Is Currently Very Active

by Keith Cowing

Norris Geyser Basin is known for being the hottest and most dynamic of Yellowstone National Park’s thermal areas—and that’s saying something! It is home to Steamboat Geyser, the tallest active […]

Conceptual Challenges In Astrobiological Analog Environments And Paths Toward Resolution

by Keith Cowing

Analog environments are terrestrial environments that resemble extraterrestrial sites; this concept originated in space sciences for defining methods to study planetary geology, training for missions and testing research instruments.
