Survival of habitable planets in unstable planetary systems [PDF]
Many observed giant planets lie on eccentric orbits. Such orbits could be the result of strong scatterings with other giant planets. The same dynamical instability that produces these scatterings may also cause habitable planets in interior orbits to become ejected, destroyed, or be transported out of the habitable zone.

Orbital Dynamics and the Evolution of Planetary Habitability in the AU Mic System [PDF]
The diversity of planetary systems that have been discovered are revealing the plethora of possible architectures, providing insights into planet formation and evolution. They also increase our understanding of system parameters that may affect planetary habitability, and how such conditions are influenced by initial conditions.

Degassing of CO2 triggers large-scale loss of helium from magma oceans
The moon-forming impact caused widespread melting and vaporization of the proto-Earth, leading to the formation of a protolunar disk1,2. Volatile elements trapped in the inner parts of the disk condensed together with heavier elements into a global magma

Identification and characterization of a new ensemble of cometary organic molecules
A new analysis of Rosetta mass spectra reveals an ensemble of complex organic molecules with striking similarities to other organic reservoirs in the Solar System, including Saturn’s ring rain material, pointing at a likely joint prestellar history.

The frequent dust storms and charged dust particles on Mars pose significant challenges to the power generation efficiency and service life of solar panels during exploration missions. This paper proposes a novel wind‐driven ternary four‐phase soft‐soft contact triboelectric nanogenerator (FPS‐TENG) for dust removal.

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 ...

Accounting for Multiplicity in Calculating Eta Earth [PDF]
Using the updated exoplanet population parameters of our previous study, which includes the planetary radius updates from Gaia DR2 and an inferred multiplicity distribution, we provide a revised $\eta_{\oplus}$ calculation. This is achieved by sampling planets from our derived population model and determining which planets meet our criterion for ...

Through a systematic literature review, we show that camera traps (CTs) have been underutilised for farmland biodiversity monitoring. The few existing farmland‐based CT studies focused on local‐level management issues, such as disease transmission between wildlife and livestock, crop damage and use of artificial feeders and water troughs by wildlife ...

ABSTRACT Recently, scholarly communities of practice have emerged with the objective of decolonizing knowledge practices within sustainable development. Their contributions to sustainability and systems change remain underexplored, possibly due to the absence of appropriate conceptual tools to analyze them. This study applies a new conceptual framework
