Habitability of Mars: How Welcoming Are the Surface and Subsurface to Life on the Red Planet?

Geosciences, 2019
Mars is a planet of great interest in the search for signatures of past or present life beyond Earth. The years of research, and more advanced instrumentation, have yielded a lot of evidence which may be considered by the scientific community as proof of

Prolonged Multi‐Phase Magmatism Due To Plume‐Lithosphere Interaction as Applied to the High Arctic Large Igneous Province

Geochemistry, Geophysics, Geosystems
The widespread High Arctic Large Igneous Province (HALIP) exhibits prolonged melting over more than 50 Myr, an observation that is difficult to reconcile with the classic view that large igneous provinces (LIPs) originate from melting in plume heads ...

Dynamics of Y dwarf atmospheres

Astronomy & Astrophysics
Context. The global circulation regime of the coolest class of brown dwarfs, known as the Y dwarfs, remains largely unexplored. Aims. We aim to investigate the interplay between convection, rotation, and cloud thermal feedback through a selected sample ...

Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,

Mission Architecture to Characterize Habitability of Venus Cloud Layers via an Aerial Platform

Aerospace, 2022
Venus is known for its extreme surface temperature and its sulfuric acid clouds. But the cloud layers on Venus have similar temperature and pressure conditions to those on the surface of Earth and are conjectured to be a possible habitat for microscopic ...

Habitability : a review

, 2016
Habitability is a widely used word in the geoscience, planetary science, and astrobiology literature, but what does it mean? In this review on habitability, we define it as the ability of an environment to support the activity of at least one known ...

Exploring Cultural and Individual Differences in the Hierarchy of Moral Concern: Evidence From Student Samples Across 41 Cultural Groups

European Journal of Social Psychology, EarlyView.
ABSTRACT Many important historical and contemporary ethical debates (e.g., on slavery, abortion and environmental protection) reflect disagreements about what we owe to different groups of individuals. Recent work in moral psychology has uncovered a seemingly replicable hierarchy of moral concern, but these studies were conducted in a few countries ...

A Terminology and Quantitative Framework for Assessing the Habitability of Solar System and Extraterrestrial Worlds

The Planetary Science Journal
The search for extraterrestrial life in the solar system and beyond is a key science driver in astrobiology, planetary science, and astrophysics. A critical step is the identification and characterization of potential habitats, both to guide the search ...
