MHD Study Of Extreme Space Weather Conditions For Exoplanets With Earth-like Magnetospheres: On Habitability Conditions And Radio-emission
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 […]
Constraints On Europa’s Water Group Torus From HST/COS Observations
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 Was Shaped By Primordial Hydrogen Atmospheres
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 […]
Approaches for Retrieving Sulfur Species Abundances from Dual X/Ka Band Radio Occultations of Venus with EnVision and VERITAS
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.
ASU-led Team Defends Molecular Oxygen Findings
When did molecular oxygen, the gas that all large and complex forms of life on Earth today require to function, first appear on Earth?
Using Stars To Study Titan’s Atmosphere
With its thick atmosphere and mysterious weather patterns, Saturn’s largest moon, Titan, is an alien world ripe with discovery potential.
The Runaway Greenhouse Effect on Hycean Worlds
Hycean worlds are a proposed subset of sub-Neptune exoplanets with substantial water inventories, liquid surface oceans and extended hydrogen-dominated atmospheres that could be favourable for habitability.
Lightning Strike Creates Phosphorus Material For The First Time On Earth
After lightning struck a tree in a New Port Richey neighborhood, a University of South Florida professor discovered the strike led to the formation of a new phosphorus material. It […]
Pythia’s Oasis Has Warm liquid Spewing From The Seafloor Offering Clues To Earthquake Hazards
Editor’s note: Pythia’s Oasis is a newly-discovered seafloor seep off the coast of Oregon featuring water with a unique composition from an exceptionally deep location inside Earth. A varied ecosystem […]
