Astronomically, there are viable mechanisms for distributing organic material throughout the Milky Way. Biologically, the destructive effects of ultraviolet light and cosmic rays means that the majority of organisms arrive broken and dead on a new world. The likelihood of conventional forms of panspermia must therefore be considered low. However, the information content of damaged biological molecules might serve to seed new life (necropanspermia). 

Subsurface exolife

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

Dynamical and Biological Panspermia Constraints Within Multi-planet Exosystems.

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.


A fundamental astrobiological question is whether life can be transported between extrasolar systems. We propose a new strategy to answer this question based on the principle that life which arose

Possible Transfer of Life by Earth-Grazing Objects to Exoplanetary Systems

It is found that 107–109 objects discovered to graze the Earth’s atmosphere and shift into a Jupiter-crossing orbit could have been captured by binary star systems over the lifetime of the Solar System.

DNA sequencing and predictions of the cosmic theory of life

The theory of cometary panspermia, developed by the late Sir Fred Hoyle and the present author argues that life originated cosmically as a unique event in one of a great multitude of comets or

Panspermia in a Milky Way–like Galaxy

We study the process of panspermia in Milky Way–like galaxies by modeling the probability of successful travel of organic compounds between stars harboring potentially habitable planets. To this end,

Transfer of Rocks between Planetary Systems: Panspermia Revisited

Motivated by the recent discovery of interstellar objects passing through the solar system, and by recent developments in dynamical simulations, this paper reconsiders the likelihood for life bearing

Feasibility of Detecting Interstellar Panspermia in Astrophysical Environments

The proposition that life can spread from one planetary system to another (interstellar panspermia) has a long history, but this hypothesis is difficult to test through observations. We develop a

Sufficiently long sojourn in space of objects containing prebiotic chemical blocks also does not contribute to the origins of life on Earth, because of elimination of homochirality, if any, and of radiation induced reactions of dehydration, decarboxylation and deamination.

Survival of Life on Asteroids, Comets and Other Small Bodies

The ability of living organisms to survive on the smaller bodies in the authors' solar system is examined and certain environments theoretically might provide protection of dormant organisms against these sterilizing factors.

Resistance of Bacillus Endospores to Extreme Terrestrial and Extraterrestrial Environments

The molecular laboratory model of spore resistance mechanisms is summarized and attempts to use the model as a basis for exploration of the resistance of spores to environmental extremes both on Earth and during postulated interplanetary transfer through space as a result of natural impact processes.

Can spores survive in interstellar space?

Inactivation of spores (Bacillus subtilis) has been investigated for the first time in the laboratory by vacuum ultraviolet radiation in simulated interstellar conditions. Remarkably, damage produced

Chance and the origin of life

Random chemical reactions in the Earth's primitive hydrosphere could have generated no more than 200 bits of information, whereas the first Darwinian organism must have encoded about a million bits,

Interstellar transfer of planetary microbiota

Panspermia theories require the transport of micro-organisms in a viable form from one astronomical location to another. The evidence of material ejection from planetary surfaces, of dynamical orbit

Lithopanspermia in star-forming clusters.

The lithopanspermia hypothesis in star-forming groups and clusters is considered, where the chances of biological material spreading from one solar system to another is greatly enhanced because of the close proximity of the systems and lower relative velocities.
