Viruses in astrobiology

Frontiers in Microbiology, 2022
Viruses are the most abundant biological entities on Earth, and yet, they have not received enough consideration in astrobiology. Viruses are also extraordinarily diverse, which is evident in the types of relationships they establish with their host ...

Venus, an Astrobiology Target. [PDF]

Bulletin of the AAS, 2021
We present a case for the exploration of Venus as an astrobiology target-(1) investigations focused on the likelihood that liquid water existed on the surface in the past, leading to the potential for the origin and evolution of life, (2) investigations ...

Future space experiment platforms for astrobiology and astrochemistry research

npj Microgravity, 2023
Space experiments are a technically challenging but a scientifically important part of astrobiology and astrochemistry research. The International Space Station (ISS) is an excellent example of a highly successful and long-lasting research platform for ...

Astrobiology of life on Earth. [PDF]

Environmental Microbiology, 2021
Astrobiology is often regarded as the study of life beyond Earth, but here we consider life on Earth through an astrobiological lens. Microbiology has historically focused on various anthropocentric sub-fields (such as fermented foods or commensals and ...

Widening Perspectives: The Intellectual and Social Benefits of Astrobiology, Big History, and the Exploration of Space [PDF]

Journal of Big History, Vol III(3), pp. 205 - 224, 2019, 2019
Astrobiology is the field of science devoted to searching for life elsewhere in the Universe. It is inherently interdisciplinary, integrating results from multiple fields of science, and in this respect has strong synergies with 'big history'. I argue that big history and astrobiology are both acting to widen human perspectives in intellectually and ...

Habitability of galaxies and application of merger trees in astrobiology [PDF]

Stojkovi\'c, N., Vukoti\'c, B., \'Cirkovi\'c, M.M., 2019, Serbian Astronomical Journal, 198, 25-43, 2019
Galaxies represent the main form of organization of matter in our universe. Therefore, they are of obvious interest for the new multidisciplinary field of astrobiology. In particular, to study habitability of galaxies represents one of the main emerging challenges of theoretical and numerical astrobiology.

Habitability Models for Astrobiology. [PDF]

Astrobiology, 2021
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades to study the habitability of Earth from local to global scales ...

Astrobiological Complexity with Probabilistic Cellular Automata [PDF]

Orig. Life Evol. Biosph. 42 (2012) 347-371, 2012
Search for extraterrestrial life and intelligence constitutes one of the major endeavors in science, but has yet been quantitatively modeled only rarely and in a cursory and superficial fashion. We argue that probabilistic cellular automata (PCA) represent the best quantitative framework for modeling astrobiological history of the Milky Way and its ...

Exoplanets – search methods, discoveries, and prospects for astrobiology [PDF]

, 2008
Whereas the Solar System has Mars and Europa as the best candidates for finding fossil/extant life as we know it - based on complex carbon compounds and liquid water - the 263 (non-pulsar) planetary systems around other stars as known at 15 September ...

The archaeal class Halobacteria and astrobiology: Knowledge gaps and research opportunities

Frontiers in Microbiology, 2022
Water bodies on Mars and the icy moons of the outer solar system are now recognized as likely being associated with high levels of salt. Therefore, the study of high salinity environments and their inhabitants has become increasingly relevant for ...
