LIFE‐VALUE NARRATIVES AND THE IMPACT OF ASTROBIOLOGY ON CHRISTIAN ETHICS

Zygon, 2016
“Pale Blue Dot” and “Anthropocene” are common tropes in astrobiology and often appear in ethical arguments. Both support a decentering of human life relative to biological life in terms of value.

Terrestrial atmosphere, water and astrobiology

EPJ Web of Conferences, 2010
Primitive life, defined as a chemical system capable to transfer its molecular information via self-replication and also capable to evolve, originated about 4 billion years ago from the processing of organic molecules by liquid water.

On the Stability of Deinoxanthin Exposed to Mars Conditions during a Long-Term Space Mission and Implications for Biomarker Detection on Other Planets

Frontiers in Microbiology, 2017
Outer space, the final frontier, is a hostile and unforgiving place for any form of life as we know it. The unique environment of space allows for a close simulation of Mars surface conditions that cannot be simulated as accurately on the Earth. For this

Space as a Tool for Astrobiology: Review and Recommendations for Experimentations in Earth Orbit and Beyond

, 2017
The space environment is regularly used for experiments addressing astrobiology research goals. The specific conditions prevailing in Earth orbit and beyond, notably the radiative environment (photons and energetic particles) and the possibility to ...

Earth as a Tool for Astrobiology—A European Perspective

, 2017
Scientists use the Earth as a tool for astrobiology by analyzing planetary field analogues (i.e. terrestrial samples and field sites that resemble planetary bodies in our Solar System).

Ethics and the Potential Conflicts between Astrobiology, Planetary Protection, and Commercial Use of Space

Challenges, 2017
A high standard of planetary protection is important for astrobiology, though the risk for contamination can never be zero. It is therefore important to find a balance.

Can Collimated Extraterrestrial Signals be Intercepted?

, 2014
The Optical Search for Extraterrestrial Intelligence (OSETI) attempts to detect collimated, narrowband pulses of electromagnetic radiation. These pulses may either consist of signals intentionally directed at the Earth, or signals between two star ...
