Within the next decade, atmospheric O2 on Earth-like M dwarf planets may be accessible with visible–near-infrared, high spectral resolution extremely large ground-based telescope (ELT) instruments.
In this study, we employ and modify the Lorenz energy cycle (LEC) framework as another way to understand the atmospheric circulation on tidally locked terrestrial planets.
Carbon monoxide (CO) is predicted to be the dominant carbon-bearing molecule in giant planet atmospheres, and, along with water, is important for discerning the oxygen and therefore carbon-to-oxygen ratio of […]
Astrobiology.com Editor’s Note: as we start to send our robotic astrobiology explorers to the Jovian system to explore icy ocean worlds Europa, Ganymede, and Callisto, the skills developed exploring (the […]
The present study aims at characterizing the habitability conditions of exoplanets with an Earth-like magnetosphere inside the habitable zone of M stars and F stars like tau Boo, caused by […]
In-situ plasma measurements as well as remote mapping of energetic neutral atoms around Jupiter provide indirect evidence that an enhancement of neutral gas is present near the orbit of the […]
Earth’s water, intrinsic oxidation state, and metal core density are fundamental chemical features of our planet. Studies of exoplanets provide a useful context for elucidating the source of these chemical […]
The EnVision and VERITAS missions to Venus will fly with X and Ka band telecommunications channels which can be used to conduct radio occultation studies of Venus’ atmosphere.
When did molecular oxygen, the gas that all large and complex forms of life on Earth today require to function, first appear on Earth?
With its thick atmosphere and mysterious weather patterns, Saturn’s largest moon, Titan, is an alien world ripe with discovery potential.
