We introduce an improved and fast inversion tool that is able to provide the thermodynamics of the solar atmosphere from the photosphere to the top of the chromosphere, as well as the integrated radiative losses (IRLs) in the chromosphere for data ...

ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Technosignatures Longevity and Lindy's Law
The probability of detecting technosignatures (i.e., evidence of technological activity beyond Earth) increases with their longevity, or the time interval over which they manifest.

Search for Extraterrestrial Intelligence (SETI) by fractal universe
We propose the hypothesis that the universes we live are provided with fractal properties, from macro to micro scale, which have self-similarity and space filling.

Significant Far‐Right Challenges to Australian Society? The XYZ and AustraliaOne
ABSTRACT Scholars who analyse the Australian far‐right from a criminological or security studies perspective propose that activists and groups pose ‘political’ challenges to Australian society. This paper examines the far‐right news website The XYZ and the AustraliaOne political party, and argues that claims that the far‐right may normalise ...

Rotational Doppler Cartography of Technosignatures on Unresolved Planets
The discovery of many Earth-like planets has renewed interest in whether life and technological civilizations exist elsewhere. The Search for Extraterrestrial Intelligence (SETI) seeks evidence for technological civilizations via technosignatures across ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
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 ...

On the Search for Extraterrestrial Intelligence (SETI) [PDF]
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.

Undetected Past Contacts with Technological Species: Implications for Technosignature Science
In the search for extraterrestrial intelligence (SETI), the highly incomplete sampling of the technosignature search space is often considered as a plausible explanation for the persistent lack of detections over six decades of searches. If correct, this
