THE EVOLUTION OF STELLAR ROTATION AND THE HYDROGEN ATMOSPHERES OF HABITABLE-ZONE TERRESTRIAL PLANETS [PDF]

, 2015
Terrestrial planets formed within gaseous protoplanetary disks can accumulate significant hydrogen envelopes. The evolution of such an atmosphere due to XUV driven evaporation depends on the activity evolution of the host star, which itself depends ...

Prospects for the habitability of OGLE-2006-BLG-109L

, 2008
The extrasolar system OGLE-2006-BLG-109L is the first multiple-planet system to be discovered by gravitational microlensing (Gaudi et al., 2008); the two large planets that have been detected have mass ratios, semimajor axis ratios, and equilibrium ...

Microalgae: A Solution for Food Security and Multiplanetary Farming

Food Frontiers, EarlyView.
ABSTRACT Human civilization is threatened by food insecurity and habitat loss owing to the cumulative effects of anthropogenic and natural factors. Thus, increasing food production while using fewer resources and exploring the potential of interstellar migration is essential.

Antarctica's vegetation in a changing climate

WIREs Climate Change, Volume 14, Issue 1, January/February 2023., 2023
Antarctica's unique terrestrial ecosystems are changing with significant impact on the local vegetation. Change is manifold and includes alterations in abiotic and biotic interactions. How the vegetation will respond is still unclear. Abstract Antarctica plays a central role in regulating global climatic and oceanographic patterns and is an integral ...

Characterization of potentially habitable planets: Retrieval of atmospheric and planetary properties from emission spectra [PDF]

, 2013
Context. An increasing number of potentially habitable terrestrial planets and planet candidates are found by ongoing planet search programs. The search for atmospheric signatures to establish planetary habitability and the presence of life might be ...

Interior Controls on the Habitability of Rocky Planets [PDF]

Space: Science & Technology
No matter how fascinating and exotic other terrestrial planets are revealed to be, nothing generates more excitement than announcements regarding their habitability. From the observation of Mars to present-day efforts toward Venus and the characterization of exoplanets, the search for life, or at least environments that could accommodate life, has been

Long‐term hydrologic connectivity on the Australian dryland margins: Evidence from the Willandra Lakes World Heritage Area over the last 60 ky

Journal of Quaternary Science, EarlyView.
ABSTRACT The semi‐arid Australian continental inland is increasingly subject to climatic extremes such as drought and flooding. Combined with the exceptionally low topographic relief characteristic of this region, hydroclimatic extremes can have an enormous impact on the land surface.

The galactic habitable zone of the Milky Way and M31 from chemical evolution models with gas radial flows

, 2014
The galactic habitable zone is defined as the region with sufficient abundance of heavy elements to form planetary systems in which Earth-like planets could be born and might be capable of sustaining life, after surviving to close supernova explosion ...

Impact of glacial cycles and ocean currents on radiation events in the Japanese turban snail Lunella coreensis

Limnology and Oceanography Letters, EarlyView.
Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

The past and future habitability of planet Mars [PDF]

Current Biology, 2014
SummaryResults from NASA’s Curiosity rover reveal traces of bygone aqueous environments with sufficiently benign conditions for some of Earth’s hardier extremophiles to thrive. If Mars hosted life in the past, it may do so again in the future, as a project to colonise our neighbour planet is now recruiting volunteers for the one-way trip. Michael Gross
