Abstract We study the prospects for life on planets with subsurface oceans, and find that a wide range of planets can exist in diverse habitats with ice envelopes of moderate thickness. We quantify the energy sources available to these worlds, the rate of production of prebiotic compounds, and assess their potential for hosting biospheres. Life on these planets is likely to face challenges, which could be overcome through a combination of different mechanisms. We estimate the number of such… 
Colloquium: Physical constraints for the evolution of life on exoplanets
Since the 1990s over 4000 exoplanets have been discovered: which of them could also develop and harbor life? It is posited that the planet must have liquid water, a surrounding atmosphere, and must
Dynamical and Biological Panspermia Constraints Within Multi-planet Exosystems.
TLDR
This work derives a probability distribution function for life-bearing debris to reach a planetary orbit, and describes the survival of micro-organisms during planetary ejection, their journey through interplanetary space, and atmospheric entry.
Is Life Most Likely Around Sun-like Stars?
We consider the habitability of Earth-analogs around stars of different masses, which is regulated by the stellar lifetime, stellar wind-induced atmospheric erosion, and biologically active
Is Extraterrestrial Life Suppressed on Subsurface Ocean Worlds due to the Paucity of Bioessential Elements?
The availability of bioessential elements for "life as we know it", such as phosphorus (P) or possibly molybdenum (Mo), is expected to restrict the biological productivity of extraterrestrial
Evaluating the Microbial Habitability of Rogue Planets and Proposing Speculative Scenarios on How They Might Act as Vectors for Panspermia
TLDR
The possibility that these types of rogue planets could harbor unicellular organisms, conceivably based on a variety of different energy sources, including chemical, osmotic, thermal, and luminous energy is discussed.
Role of stellar physics in regulating the critical steps for life
Abstract We use the critical step model to study the major transitions in evolution on Earth. We find that a total of five steps represents the most plausible estimate, in agreement with previous
Brown Dwarf Atmospheres as the Potentially Most Detectable and Abundant Sites for Life
We show that the total habitable volume in the atmospheres of cool brown dwarfs with effective temperatures of $\sim 250$-$350$ K is possibly larger by two orders of magnitude than that of Earth-like
The Habitability of the Galactic Bulge
TLDR
Analytical models of the star density in the bulge are used to provide estimates of the rate of catastrophic events and of the diffusion timescales for life over interstellar distances.
Super-Earths in need for Extremly Big Rockets
Many rocky exoplanets are heavier and larger than Earth, so-called "Super-Earths". Some of these may be habitable, and a few may be inhabited by Super-Earthlings. Due to the higher surface gravity on

Abstract Many rocky exoplanets are heavier and larger than the Earth and have higher surface gravity. This makes space-flight on these worlds very challenging because the required fuel mass for a

Physical constraints on the likelihood of life on exoplanets
Abstract One of the most fundamental questions in exoplanetology is to determine whether a given planet is habitable. We estimate the relative likelihood of a planet's propensity towards habitability
THE STEPPENWOLF: A PROPOSAL FOR A HABITABLE PLANET IN INTERSTELLAR SPACE
Rogue planets have been ejected from their planetary system. We investigate the possibility that a rogue planet could maintain a liquid ocean under layers of thermally insulating water ice and frozen
Energy for microbial life on Europa
TLDR
It is shown that disequilibrium chemistry in the ocean's ice cover, driven by charged particles accelerated in Jupiter's magnetosphere, should produce enough organic and oxidant molecules to fuel a substantial Europan biosphere.
The Interior Dynamics of Water Planets
The ever-expanding catalog of detected super-Earths calls for theoretical studies of their properties in the case of a substantial water layer. This work considers such water planets with a range of
Implications of Tides for Life on Exoplanets.
TLDR
This work identifies the conditions under which tides may exert a significant positive influence on biotic processes including abiogenesis, biological rhythms, nutrient upwelling, and stimulating photosynthesis and identifies large-scale algal blooms as potential temporal biosignatures in reflectance light curves that can arise indirectly as a consequence of strong tidal forces.
Are extrasolar oceans common throughout the Galaxy
Light and cold extrasolar planets such as OGLE 2005-BLG-390Lb, a 5.5 Earth masses planet detected via microlensing, could be frequent in the Galaxy according to some preliminary results from
Life in Ice-Covered Oceans
TLDR
Nearly all metabolic life-styles on the present Earth will be denied to organisms on Europa and which types of organisms, if any, are most likely to be found there are indicated.
Seeding life on the moons of the outer planets via lithopanspermia.
TLDR
It is expected that material from Earth and Mars to the moons of Jupiter and Saturn is most likely to occur during the Late Heavy Bombardment or during the ensuing 1-2 billion years, and there are significant rates of re-impact in the first million years after ejection.
