The Design of a Bioinspired Integrated Total Habitability Instrument for Planetary Exploration: A Review of Potential Sensing Technologies [PDF]

open access: yesBiomimetics
One key objective of astrobiology is to investigate and discover if other planetary bodies are habitable. The determination of whether an environment is habitable to known life requires measuring liquid water, CHNOPS elements, other nutrients, and energy

Growth, physiology, and metabolism of Halomonas meridiana in aqueous ammonium sulfate with implications for icy moon astrobiology [PDF]

open access: yesFrontiers in Microbiology
The discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan. Tentative evidence of ammonium sulfate ((NH4)2SO4) has been detected on the surface of Europa, and (NH4)2SO4 could be a prominent ...

Life on Venus? [PDF]

open access: yesLife
Venus is not generally at the forefront when considering extraterrestrial life. Yet, based on the physical similarities and proximity to Earth and with the little knowledge of its evolutionary history, there is a possibility that Venus may have hosted ...

Habits [PDF]

open access: yesCurrent Biology, 2017
What is a habit? One problem with the concept of habit has been that virtually everyone has their own ideas of what is meant by such a term. Whilst not eschewing folk psychology, it is useful to re-examine dictionary definitions of 'habit'. The Oxford Dictionary of English defines habit as "a settled or regular tendency or practice, especially one that

Multiverse Predictions for Habitability: Stellar and Atmospheric Habitability

open access: yesUniverse, 2022
Stellar activity and planetary atmospheric properties have the potential to strongly influence habitability. To date, neither have been adequately studied in the multiverse context, so there has been no assessment of how these effects impact the ...

Hard rock dark biosphere and habitability

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The discovery that most of the prokaryotic diversity and biomass on Earth resides in the deep subsurface, calls for an improved definition of habitability, which should consider the existence of dark biospheres in other planets and moons of the Solar ...

Multiverse Predictions for Habitability: Planetary Characteristics

open access: yesUniverse, 2022
Recent detections of potentially habitable exoplanets around sunlike stars demand increased exploration of the physical conditions that can sustain life, by whatever methods available.

Terminator Habitability: The Case for Limited Water Availability on M-dwarf Planets

open access: yesThe Astrophysical Journal, 2023
Rocky planets orbiting M-dwarf stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets in the M-dwarf habitable zone are likely synchronously rotating, such that we expect significant day–night ...

Modeling Virus and Bacteria Populations in Europa’s Subsurface Ocean

open access: yesLife, 2022
The search for life in the universe is often informed by the study of “extreme” environments on Earth, which provide analogs for habitable locations in the Solar System, and whose microbial inhabitants may therefore also serve as analogs for potential ...

Multiverse Predictions for Habitability: Origin of Life Scenarios

open access: yesUniverse, 2023
If the origin of life is rare and sensitive to the local conditions at the site of its emergence, then, using the principle of mediocrity within a multiverse framework, we may expect to find ourselves in a universe that is better than usual at creating ...
