Key research themes

1. How can we empirically detect and characterize extraterrestrial impact events in Earth's geological record?

This theme centers on the methodologies to identify evidence of extraterrestrial impacts in Earth's stratigraphic and sedimentary record, focusing on signatures such as elevated cosmogenic isotopes, nanodiamonds, ejecta layers, and geomorphological structures. It is critical for reconstructing the frequency, magnitude, and environmental consequences of cosmic impacts, facilitating better hazard assessment and understanding of Earth's geological history.

Key finding: Documented a ~fivefold 3He isotope anomaly in deep-sea sediment cores coinciding with the catastrophic disruption of the Veritas asteroid family ca. 8.3 ± 0.5 Ma, corroborated by multiproxy stratigraphic analyses (magnetic... Read more
Key finding: Confirmed the presence of a pronounced 3He anomaly in late Tortonian sediments linked to the Veritas asteroid breakup through high-resolution multiproxy stratigraphy, reinforcing the geochronological framework for this impact... Read more
Key finding: Presented accelerator mass spectrometry radiocarbon dates demonstrating wildfires postdating the hypothesized Younger Dryas impact event, and critically assessed nanodiamond presence in sedimentary horizons traditionally... Read more
Key finding: Uncovered early conceptualizations of extraterrestrial impacts in mid-19th century German science, where Ludwig Pfeil and Karl Reichenbach independently theorized Earth formed from meteoritic masses and had undergone multiple... Read more

2. What are the technological strategies and outcomes of kinetic impactor missions for asteroid deflection and planetary defense?

This theme investigates the design, execution, and effectiveness of kinetic impactor technology, specifically space missions aimed at testing asteroid deflection capabilities for planetary defense. It is significant for validating mitigation strategies to prevent potentially catastrophic asteroid impacts with Earth.

Key finding: Although primarily focused on exoplanetology and the challenges of anticipating unknown phenomena, this paper highlights the need for scientific exploratory strategies that accommodate unpredicted findings. This perspective... Read more
Key finding: Reported the first successful autonomous kinetic impact into the near-Earth asteroid Dimorphos by NASA's DART mission, demonstrating that kinetic impactor technology can measurably alter an asteroid's orbit. Detailed... Read more
Key finding: Complemented the above DART mission findings with a focus on the engineering and operational details, confirming that the 151-meter diameter Dimorphos was impacted successfully resulting in a measurable orbital period change.... Read more

3. What are the societal, ethical, and communicative implications of extraterrestrial life discovery and space exploration?

This theme addresses the interdisciplinary concerns around human reactions to discoveries of extraterrestrial life, the cultural framing of astrobiology in mass media, ethical frameworks for extraterrestrial environmental impact, and inclusivity of diverse philosophical approaches in space exploration ethics. Such investigations are essential for responsible policy-making and enhancing public engagement.

Key finding: Through empirical analysis of media and public response via linguistic inquiry, this study found predominantly positive and reward-oriented emotional reactions in hypothetical and historical contexts of extraterrestrial... Read more
Key finding: Outlined the establishment of a research roadmap and interdisciplinary focus group integrating humanities and social sciences with astrobiology to systematically examine cultural, societal, and psychological implications of... Read more
Key finding: Critically reviewed current international policies and legal gaps regarding environmental impact assessments beyond Earth, emphasizing lack of enforceable protocols for extraterrestrial environmental protections. Proposed... Read more

Key finding: Analyzed dominant media frames in German news between 2009 and 2022, identifying 'beneficial space exploration,' 'UAP/extraterrestrial intelligence,' and 'SETI risk' as primary narratives. Discovered that scientific sources... Read more
Key finding: Argued for the integration of Indigenous American philosophy and Global South epistemologies into astrobioethics, emphasizing the nascent state of this ethics subfield as an opportunity to counteract colonial legacies and... Read more
Key finding: Presented a feminist critique of dominant extraterrestrial intelligence (ETI) paradigms characterized by male bias, abstractionism, and universalist assumptions. Proposed feminist approaches emphasizing relationality,... Read more
Key finding: Explored theological and ethical issues emerging from the likely discovery of non-intelligent extraterrestrial microbial life, highlighting neglected concerns such as planetary contamination, long-term stewardship, and... Read more

4. What are the risks and benefits associated with Earth-originating radio transmissions detectable by extraterrestrial civilizations?

This theme investigates the potential hazards and advantages of Earth's radio emissions, both intentional (METI) and unintentional, in the context of extraterrestrial detection and contact. It assesses transmission detectability, consequences of contact, and policy frameworks for managing long-term radio communication strategy.

Key finding: Quantified relative detectability of deliberate METI signals versus pervasive terrestrial radio emissions, finding METI attempts vastly less detectable than routine Earth sources like military radars. Developed an analytic... Read more
