New Research Strengthens Link Between Glaciers And Earth's 'Great Unconformity
New research provides further evidence that rocks representing up to a billion years of geological time were carved away by ancient glaciers during the planet’s “Snowball Earth” period, according to […]

Mapping The Surface Of Partially Cloudy Exoplanets Is Hard
Reflected light photometry of terrestrial exoplanets could reveal the presence of oceans and continents, hence placing direct constraints on the current and long-term habitability of these worlds.

Atmospheric Dynamics Of Temperate Sub-Neptunes. Part I: Dry Dynamics
Sub-Neptunes (planets with radii between 2 and 4 R⊕) are abundant around M-dwarf stars, yet the atmospheric dynamics of these planets is relatively unexplored. In this paper, we aim to […]

Deadliest Period In Earth's History Was Also The Stinkiest
Tiny microbes belching toxic gas helped cause — and prolong — the biggest mass extinction in Earth’s history, a new study suggests. Generally, scientists believe Siberian volcanos spitting greenhouse gases […]

The Atmospheres Of Rocky Exoplanets II. Influence Of Surface Composition On The Diversity Of Cloud Condensates
Clouds are an integral part of planetary atmospheres, with most planets hosting clouds. The understanding of not only the formation, but also the composition of clouds is crucial to the […]

Climate Change Impact On Earth's Life Zones On Track To Accelerate
Scientists have revealed that climate change has already impacted all of Earth’s ‘life zones’ and the effects are set to triple under business-as-usual emissions growth. A University of Queensland and […]

How Does The Background Atmosphere Affect The Onset Of The Runaway Greenhouse?
As the insolation of an Earth-like (exo)planet with a large amount of water increases, its surface and atmospheric temperatures also increase, eventually leading to a catastrophic runaway greenhouse transition. While […]
