Giant impacts are believed to play a major role in the assembly, long-term orbital stability, and resonant structure of exoplanetary systems.

NASA] Terra Sirenum is a heavily cratered region of Mars’ ancient Southern Highlands. A blanket of dust, possibly cemented by ice, covers much of the ancient bedrock in these Martian middle latitudes, ...

NASA is inviting the public to send their names aboard the agency’s Dragonfly rotorcraft and be part of the first science mission to fly and explore the surface of another world. To have your name ...

The origin of biological homochirality remains a central enigma in astrobiology. The emergence of a homochiral world necessitates two key processes: initial symmetry breaking and subsequent chiral ...

Schematic overview of the coupled atmosphere-interior evolution model. This model considers the diffusion of atmospheric H2 into the magma ocean, redox reactions in the magma ocean, partitioning of ...

Polygons are interesting features on Mars, though sometimes only visible in high resolution images like those taken by HiRISE.

Scientists at the University of New Mexico have played a key role in identifying a rare, 4.1-billion-year-old Martian meteorite ...

A consensus established by extensive thermodynamic and structural studies of that water acts as an indispensable structural cofactor ...

[Canadian Space Agency]. The presence of methane on Mars could provide important clues about the red planet’s past and present, including whether it may once have supported life. By studying methane ...

We present the results of an initial study into the feasibility and design of the Enceladus Thermal Mapper (ETM) ...

The prebiotic chemistry necessary for the development of life requires a low-probability combination of steps to reach the complexity of a living cell.

Sulfur allotrope chemistry could be a candidate for buffering sulfur atoms, as it can grow into long chains. Sulfur hydrides such as H 2 S is considered as one of the main sulfur-bearing compounds, ...
