Earth As A Potential Source Of Llife For Europa’s Subsurface Ocean
The paper discusses the possibility of dust particles containing living bacteria ejected from Earth reaching Europa and landing on its surface. It is shown that, taking certain factors into account, over a period of 30 − 80 Myr (the estimated age of Europa’s ocean), Jupiter’s moon would have been impacted…
Keep readingDust To Dust: Prospects For Passive Technosignatures As Relics Of ETI
Technological societies are separated in time, not just space — that is the lesson of the Drake equation. Might the best way to seek them be to find technosignatures that persist long after their creators? I present work I and my collaborators have done on the idea of passive technosignatures,…

A Cross-Laboratory Comparison Study of Titan Haze Analogs: Surface Energy II
[astro-ph.EP] The organic haze particles on Titan play important roles in atmospheric cloud formation and aerosol-lake interactions. These processes are strongly influenced by the surface energy of the haze particles, which controls cohesion and wetting behavior. This study presents a comparative analysis of 32 laboratory-produced haze analog samples (“tholins”) synthesized across three laboratories. Using contact…
