Earth’s ‘Boring Billion’ Years Created The Conditions For Complex Life
A study led by researchers from the University of Sydney and the University of Adelaide has revealed how the breakup of an ancient supercontinent 1.5 billion years ago transformed Earth’s […]
Microbes At Red Sea Vents Show How Life And Geology Shape Each Other
A new study led by King Abdullah University of Science and Technology (KAUST; Saudi Arabia) Professor Alexandre Rosado has revealed an unusual microbial world in the Hatiba Mons hydrothermal vent […]
An Introduction To Mars Terraforming – 2025 Workshop Summary
Terraforming Mars is an age old science fiction concept now worth revisiting through the lens of modern science and technology. This document serves as a summary of contemporary ideas about […]
The First Dedicated Survey of Atmospheric Escape from Planets Orbiting F Stars
Hydrodynamic escape can strip the envelopes of close-in exoplanets, but most observations of atmospheric mass loss to date have been confined to planets orbiting K and M dwarfs.
Using Venus, Earth, and Mars to Understand Exoplanet Volatile and Climate Evolution
Venus, Earth, and Mars exhibit a wide range of interactions between their deep interiors, surfaces, lower and upper atmospheres, and the Sun, with commensurate variations in the nature of their […]
Microbial Exoenzymes Catalyzed The Transition To An Oxygenated Earth
Microbial exoenzymes—extracellular enzymes secreted to degrade complex organic polymers— are essential for recycling carbon and nutrients, thus sustaining primary productivity in today’s oceans.
Earth’s Oxygen Boom: A Fresh Perspective For A Billion-year-old Problem
The appearance of oxygen in Earth’s atmosphere was a turning point in the history of our planet, forever transforming the environment and setting the stage for complex life. This event, […]
Did Mars Once Have an Ocean? New Research Suggests Yes
Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of […]
Re-accretion of Giant Impact Ejecta Can Drive Significant Atmospheric Erosion on Terrestrial Planets
Giant impacts, the collisions between planetary embryos, play a crucial role in sculpting the planets and their orbital architectures.
