Mars As An Exoplanet: Lessons From A Planet At The Edge Of Habitability

Mars is the Solar System’s canonical small, rocky planet that transitioned from early geologic activity and surface liquid water to a cold and arid planet with a thin, cold, CO2-dominated […]

Resistive MHD Simulations of Stellar Wind-Magnetosphere Coupling in TRAPPIST-1e

Close-in terrestrial exoplanets around M dwarfs reside in dense, magnetized winds, where non-ideal plasma coupling can strongly affect how electromagnetic energy is redistributed within the dayside interaction region.

The Impact Of Stellar Winds And Tidal Locking Effects On The Habitability Of Earth-like Exoplanets Around M Dwarf Stars

We present an assessment of the effects of stellar wind magnetic and mechanical components on the habitability of Earth-like exoplanets orbiting the inner and outer radii of the habitable zone […]

JWST Reveals Spectral Tracers of Recent Surface Modification on Europa

Europa has been modified by a variety of geologic processes, exposing internally-derived materials that are heavily irradiated by charged particles trapped in Jupiter’s magnetosphere.

Fluorescent Biomolecules Detectable in Near-Surface Ice on Europa

Europa, Jupiter’s second Galilean moon, is believed to host a subsurface ocean in contact with a rocky mantle, where hydrothermal activity may drive the synthesis of organic molecules.
