The Venus Life Equation
Ancient Venus and Earth may have been similar in crucial ways for the development of life, such as liquid water oceans, land-ocean interfaces, the favorable chemical ingredients and energy pathways. […]

Venusian Habitable Climate Scenarios: Modeling Venus Through Time And Applications To Slowly Rotating Venus-Like Exoplanets
One popular view of Venus’ climate history describes a world that has spent much of its life with surface liquid water, plate tectonics, and a stable temperate climate. Part of […]

Revisiting The Cosmic-ray Induced Venusian Radiation Dose In The Context Of Habitability
The Atmospheric Radiation Interaction Simulator (AtRIS) was used to model the altitude-dependent Venusian absorbed dose and the Venusian dose equivalent. For the first time, we modeled the dose rates for […]

Chemically-distinct Regions Within Venus' Atmosphere Revealed by MESSENGER-measured N2 Concentrations
A defining characteristic of the planet Venus is its thick, CO2-dominated atmosphere. Despite over fifty years of robotic exploration, including thirteen successful atmosphere probes and landers, our knowledge of N2, […]

Was Venus Once Warm And Wet? New Study of Lava Flow Suggests Not
A new study of the Ovda Fluctus lava flow on Venus indicates that it is made of basaltic lava. This discovery weakens the notion that Venus might once have been […]

Could Venus Have Been Habitable?
Venus may have been a temperate planet hosting liquid water for 2-3 billion years, until a dramatic transformation starting over 700 million years ago resurfaced around 80% of the planet. […]

Predicting The Yield of Potential Venus Analogs From TESS And Their Potential for Atmospheric Characterization
The transit method is biased toward short orbital period planets that are interior to their host star’s Habitable Zone (HZ). These planets are particularly interesting from the perspective of exploring […]

Venus As A Laboratory For Exoplanetary Science
The current goals of the astrobiology community are focused on developing a framework for the detection of biosignatures, or evidence thereof, on objects inside and outside of our solar system. […]
