Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth.
Panspermia
Solid Grains Ejected From Terrestrial Exoplanets As A Probe Of The Abundance Of life In the Milky Way
Searching for extrasolar biosignatures is important to understand life on Earth and its origin.
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 rocks to […]
On Possible Life-dispersal Patterns Beyond The Earth
We model hypothetical bio-dispersal within a single Galactic region using the stochastic infection dynamics process, which is inspired by these local properties of life dispersal on Earth. We split the […]
A Material-based Panspermia Hypothesis: The Potential of Polymer Gels and Membraneless Droplets
The Panspermia hypothesis posits that either life’s building blocks (molecular Panspermia) or life itself (organism-based Panspermia) may have been interplanetary transferred to facilitate the Origins of Life (OoL) on a […]
On The Force Of Vertical Winds In The Upper Atmosphere – Consequences For Small Biological Particles
For many decades vertical winds have been observed at high altitudes of the Earth’s atmosphere, in the mesosphere and thermosphere layers. These observations have been used with a simple one […]
Sending Life To The Stars
No longer solely in the realm of science fiction, the possibility of interstellar travel has appeared, tantalizingly, on the horizon. Although we may not see it in our lifetimes — […]
Possibility Of Transporting Material From Ceres To NEO Region Via 8:3 MMR With Jupiter
In this work we investigate the possibility of transporting material to the NEO region via the 8:3 MMR with Jupiter, potentially even material released from the dwarf planet Ceres. By […]
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, we […]
Transfer of Life Between Earth and Venus with Planet-Grazing Asteroids
Recently, phosphine was discovered in the atmosphere of Venus as a potential biosignature. This raises the question: if Venusian life exists, could it be related to terrestrial life? Based on […]
