The atmospheres of the terrestrial planets
Geophysical Surveys, 1985 It has been known since the end of the nineteenth century that the Earth’s nearest planetary neighbours, Venus and Mars, have extensive atmospheres. However, the nature of these atmospheres was not at all well understood until the advent of planetary missions by robot probes, beginning with Mariner 2 which encountered Venus in December 1962. Since then,

Journal of World-Systems Research, 2023 This paper focuses upon the human migratory trajectory from eons on planet Earth to slowly moving out into orbital space and whether world-systems theory must craft new theoretical frames to grasp the possible problems arising from the existence of a ...

Detecting the Dusty Debris of Terrestrial Planet Formation
, 2004 We use a multiannulus accretion code to investigate debris disks in the terrestrial zone, at 0.7-1.3 AU around a 1 solar mass star. Terrestrial planet formation produces a bright dusty ring of debris with a lifetime of at least 1 Myr. The early phases of

Review of Evolving Planet [game]
Internet Archaeology, 2016 A review of Evolving Planet is an agent-based model situated in the archaeology of hominin dispersal, wrapped in the trappings of a casual video game. In Evolving Planet, a terrestrial world has been discovered, replete with artefacts and sites from a ...

Experimental evidence for hydrogen incorporation into Earth’s core
Nature Communications, 2021 Based on diamond-anvil cell experiments and cutting-edge secondary ion mass spectrometry analyses, the authors here show that hydrogen may be an important constituent in the Earth’s core and also in the metallic cores of any terrestrial planet or moon ...

Formation of terrestrial planet cores inside giant planet embryos
, 2010 Giant planet embryos are believed to be spawned by gravitational instability in massive extended (R ~ 100 AU) protostellar discs. In a recent paper we have shown that dust can sediment inside the embryos, as argued earlier by Boss (1998) in a slightly ...

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...

The Planetary Science Journal, 2023 The formation and subsequent migration of gas giants could significantly affect the material mixing in the solar system. In this study, we use N -body simulations to investigate how much water is transported into the region of the terrestrial planet ...
