The Survival Of Aromatic Molecules In Protoplanetary Disks
Aromaticity is a common chemical functionalities in bioactive molecules. In interstellar and circumstellar environments benzene and other small aromatics are considered the precursor for more complex prebiotic molecules and they […]

Optical Design Pathways to Fluidic Space-Assembled Reflectors & Dual-Configuration Spectrographs for Characterizing Exo-Earths
In-space assembly of optical reflectors can solve light-gathering aperture scaling, which currently limits space-borne optical telescopes. Our compass reduces the top-level optical design trade to three types of avenues—a fluidic […]

Solar Hegemony: M-Dwarfs Are Unlikely to Host Observers Such as Ourselves
With no firm evidence for life beyond our solar system, inferences about the population observers such as ourselves rests upon the Earth as a single input, at least for now.

Technosignatures Of Self-Replicating Probes In The Solar System
We explore a much-neglected area of SETI: solar system techno-signatures. As our cursory solar system exploration consolidates into commercial industrialisation, it is crucial that we determine what to look for […]

How Technological Acceleration Shrinks SETI’s Narrow Detection Window
The search for extraterrestrial intelligence (SETI) has historically focused on detecting electromagnetic technosignatures, implicitly assuming that alien civilisations are biological and technologically analogous to ourselves.

Crank-rocker Optical Fiber Mode Scrambler Prototype For The GMT-Consortium Large Earth Finder (G-CLEF)
When coherent light propagates through a multimode optical fiber, the modes interfere at the fiber exit boundary, producing a high-contrast speckle interference pattern called modal noise.
