Abstract The development of civilizations such as ours into spacefaring, multi-planet entities requires significant raw materials to construct vehicles and habitats. Interplanetary debris, including asteroids and comets, may provide such a source of raw materials. In this article, we present the hypothesis that extraterrestrial intelligences (ETIs) engaged in asteroid mining may be detectable from Earth. Considering the detected disc of debris around Vega as a template, we explore the… 
Possible Photometric Signatures of Moderately Advanced Civilizations: The Clarke Exobelt
This paper puts forward a possible new indicator of the presence of moderately advanced civilizations on transiting exoplanets. The idea is to examine the region of space around a planet where
Novel Detection Techniques for Extraterrestrial Intelligence Beyond and Inside the Solar System

  • 2012
The scientific search for extraterritorial intelligence (SETI) began when Cocconi and Morrison (1959) pointed out that human radio technology (then achievable broadcast power and detection
SAFARI: Searching Asteroids for Activity Revealing Indicators
Active asteroids behave dynamically like asteroids but display comet-like comae. These objects are poorly understood, with only about 30 identified to date. We have conducted one of the deepest
On the Possibility of Detecting Class A Stellar Engines Using Exoplanet Transit Curves
The Class A stellar engine (also known as a Shkadov thruster) is a spherical arc mirror, designed to use the impulse from a star’s radiation pressure to generate a thrust force, perturbing the star’s
Minimal Conditions for Survival of Technological Civilizations in the Face of Stellar Evolution
The ease of interstellar rocket travel is an issue with implications for the long-term fate of our own and other civilizations and for the much-debated number of technological civilizations in the
Detection technique for artificially illuminated objects in the outer solar system and beyond.
The proposed Large Synoptic Survey Telescope (LSST) and other planned surveys will provide superb data and allow measurement of α for thousands of KBOs, and it is proposed to measure the variation of the observed flux F from such objects as a function of their changing orbital distances D.

The controversial hypothesis that ‘Oumuamua (1I/2017 U1) was an alien craft dominated by a solar sail is considered using known physics for the two possible cases: controlled and uncontrolled
The Solar System: Favored for Space Travel
Here, we compare Earth to the most common type of exoplanet, the super-Earth, with respect to interplanetary space travel. The typical super-Earth should have higher gravity and atmospheric pressure
Interstellar Communication Network. I. Overview and Assumptions
It has recently been suggested in this journal by Benford that “Lurkers” in the form of interstellar exploration probes could be present in the solar system. Similarly, extraterrestrial intelligence


Metalliferous asteroids as potential sources of precious metals
Recent discoveries of near-Earth asteroids (NEAs) and chemical analyses of fragments of asteroids (meteorites) suggest that there may be a gold mine, literally, in near-Earth space. Judged from
Spectral Fingerprints of Habitability
The emerging field of extrasolar planet search has shown an extraordinary ability to combine research by astrophysics, chemistry, biology and geophysics into a new and exciting interdisciplinary
Macro-Engineering in the Galactic Context
We consider the problem of detectability of macro-engineering projects over interstellar distances, in the context of Search for ExtraTerrestrial Intelligence (SETI). Freeman J. Dyson and his
The Detectability of Exo-Earths and Super-Earths Via Resonant Signatures in Exozodiacal Clouds
Directly imaging extrasolar terrestrial planets necessarily means contending with the astrophysical noise of exozodiacal dust and the resonant structures created by these planets in exozodiacal
Evolution of Debris Disks
Circumstellar dust exists around several hundred main sequence stars. For the youngest stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be continuously
Structure in the ϵ Eridani Debris Disk
New submillimeter images have been obtained of the dust disk around the nearby K2 V star ϵ Eridani, with the total data set now spanning 5 yr. These images show the distribution of dusty debris
The archetypical debris disk around Vega has been observed intensively over the past 25 years. It has been argued that the resulting photometric data and images may be in contradiction with a
Collisional processes in extrasolar planetesimal discs – dust clumps in Fomalhaut's debris disc
This paper presents a model for the outcome of collisions between planetesimals in a debris disc, and assesses the impact of collisional processes on the structure and size distribution of the disc.
The physico-chemical history of Falling Evaporating Bodies around beta Pictoris: investigating the presence of volatiles
Transient spectral absorption events have been monitored for many years toward the star Pictoris and have been interpreted as resulting from the transit across the line of sight of evaporating
