Schematic of the modeling framework used in this study. Chemical equilibrium between the core, mantle and atmosphere is calculated using the model from H. E. Schlichting & E. D. Young

Simulation of 3I/ATLAS’s ion tail on 1 November 2025 assuming a 460 kms−1 radial flow. Positions of Europa Clipper, Sun, Hera, and 3I/ATLAS are shown in a frame where the

Overlap of planned initial sample characterization activities for curation and the SSAF test-sequence. Graph modified from Tait et al. (2022). The Committee on Space Research (COSPAR) Sample Safety Assessment Framework

Alien Wind Power – Grok via Astrobiology.com We suggest that the large-scale deployment of wind turbines on an M-dwarf planet could produce observable technosignatures. Motivated by observations of hypersonic wind

Generic structure of the taxonomy of potential biosignatures (PB). The taxonomy consists of three generic categories (chemistry, structure, activity) thought to represent universal attributes of life. Each category comprises two
