Salt-rich water ice at the surfaces of icy worlds, for example, Europa, Enceladus, and Ceres, is of particular interest for Solar System exploration as it can represent a record of […]
The discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan.
In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations.
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.
Saturn’s moon Enceladus has a global ocean that is covered by an ice shell. The moon’s eccentric orbit forces the shell to librate, which distorts the shell and thereby generates […]
Saturn’s E ring is a huge, fuzzy, donut-shaped circle of particles around Saturn, that puzzled scientists for a long time.
Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are […]
Planets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches.
Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus’ moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and […]
Determining the habitability of terrestrial exoplanets is a complex problem that represents the next major step for the astrophysical community.
