X-rays May Tell Us More About The Origins Of Visiting Space Rocks
A research team led by a Yale astronomer has some advice for our next close encounter with a wandering, interstellar object. Check its X-rays on the way out. Since 2017, […]

Searching For Life With Space Dust
Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space.

New Signatures of Bio-Molecular Complexity in the Hypervelocity Impact Ejecta of Icy Moon Analogues
Impact delivery of prebiotic compounds to the early Earth from an impacting comet is considered to be one of the possible ways by which prebiotic molecules arrived on the Earth.

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 […]

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 […]
