A TESS Test of the Hybrid Ring Strategy for Technosignature Searches Using GRB 221009A
The Astrophysical JournalWe present the first observational test of the hybrid ring strategy, a general coordinated signaling scheme proposed by N. Seto, which provides a practical Schelling point realization for interstellar signaling.

A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure
The Astronomical Journal, 2023 The search for extraterrestrial intelligence (SETI) commensal surveys aim to scan the sky to find possible technosignatures from an extraterrestrial intelligence (ETI). The mitigation of radio frequency interference (RFI) is an important step, especially

On the Search for Extraterrestrial Intelligence (SETI) [PDF]
American Journal of International Law, 2020 This article calls attention to an emerging issue deserving the involvement of the international community and international lawyers — the possibility that humanity might contact intelligent and technologically advanced life elsewhere in our galaxy and universe.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, EarlyView.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

The Astrophysical JournalThe search for extraterrestrial intelligence (SETI) is largely limited by the vastness of the signaling parameter space. The concurrent signaling scheme offers a framework in which civilizations can coordinate their transmission and reception by ...

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

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

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, EarlyView.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.This study explores the origins of life by linking prebiotic chemistry, the emergence of information‐carrying molecules such as RNA and proteins, and philosophical questions about consciousness. The study emphasizes the role of molecular evolution in the Central Dogma and provides insights into the chemical origins of biology and the basis of life's ...
