“…One other important term for all three clusters is “biosignature” ( Figure S2 ). Missions seeking bio-signatures in situ on Mars and icy moons of our Solar System are a challenging task because organisms and their metabolic products may be destroyed by the harsh conditions experienced on irradiated planetary and icy-moon surfaces [ 114 , 115 , 116 , 117 , 118 ]. Bio-signature search in distant exo-planets is a rather different task and focuses on the spectral analysis of atmospheres.…”

Life on our planet likely evolved in the ocean, and thus exo-oceans are key habitats to search for extraterrestrial life. We conducted a data-driven bibliographic survey on the astrobiology literature to identify emerging research trends with marine science for future synergies in the exploration for extraterrestrial life in exo-oceans. Based on search queries, we identified 2592 published items since 1963. The current literature falls into three major groups of terms focusing on (1) the search for life on Mars, (2) astrobiology within our Solar System with reference to icy moons and their exo-oceans, and (3) astronomical and biological parameters for planetary habitability. We also identified that the most prominent research keywords form three key-groups focusing on (1) using terrestrial environments as proxies for Martian environments, centred on extremophiles and biosignatures, (2) habitable zones outside of “Goldilocks” orbital ranges, centred on ice planets, and (3) the atmosphere, magnetic field, and geology in relation to planets’ habitable conditions, centred on water-based oceans.

“…Dok se pojedine vrste neintencionalne panspermije mogu, prema savremenim modelima, odvijati i na većim, tj. međuzvezdanim udaljenostima, čak i najoptimističniji modeli ne pridaju procesu suviše veliku efikasnost (Wallis & Wickramasinghe 2004;Napier 2004;Sadlok 2020). Ali ograničenje je daleko slabije u pogledu usmerene panspermije, koja se može podjednako dobro interpretirati i kao tehnogenička verzija opštijeg procesa panspermije.…”

Simplicity out of complexity? On physical eschatology and abiogenesis

Standard reductionist narrative about the necessity of complex systems arising from simple subsystems can be undermined from multiple directions. Here, I shall suggest an unexpected way of such undermining which occurs upon joining our best understanding of the future evolution of the universe (as outlined by physical eschatology) with the continuity thesis which plays the key role in studies of the origin of life (abiogenesis). Many aspects of evolution - including physical, chemical, and astrobiological evolution - would look quite different from what we empirically find around us at the present epoch if the history of the universe within our cosmological horizon were to be observed from a timeless ?Archimedean? point. Avoiding the pitfalls of this chronocentric bias leads to several unexpected conclusions, one of them being that the directed panspermia, coupled with advanced biotechnology, represents the most probable origin of almost all phylogenetic lineages in the universe. Therefore, complex lifeforms are required for emergence of (almost) all simple lifeforms. This has several counterintuitive and unexpected philosophical consequences.

“…The habitability of nomadic worlds remains indeterminate, although a plethora of publications have identified possible avenues whereby these objects could be rendered suitable for hosting life [67,42,32,68,69,39,33,70,40,46,71,35,41,72,37,73,36,74,38]. Hence, detecting and characterizing a nomadic world in the above size range would accord us a unique opportunity to gauge whether such abodes constitute viable habitats for life, evaluate our understanding of habitability, and determine whether prebiotic molecules and/or organisms may be transported across interstellar distances [75,76,77,58,71,73].…”
