If extraterrestrial intelligent beings exist and have reached a high level of technical development, one by-product of their energy metabolism is likely to be the large-scale conversion of starlight into far-infrared radiation. It is proposed that a search for sources of infrared radiation should accompany the recently initiated search for interstellar radio communications. 
Searching for Intelligence
Searching our solar system through optical telescopes failed to provide persuasive evidence of extraterrestrial intelligence. To pursue the question further, searchers broadened the quest with new
The case for optical SETI
After almost 40 years of fruitless search for extraterrestrial life in the radio region, Raghir Bhathal argues that it is time to expand the search to other parts of the electromagnetic spectrum.
Limitations of Chemical Propulsion for Interstellar Escape from Habitable Zones Around Low-mass Stars
The habitable zones of low-mass stars are characterized by escape speeds that can be a few times higher than the Earth's orbit around the Sun. Owing to the exponential dependence of the required fuel
The Search for Extraterrestrial Intelligence and the Nasa High Resolution Microwave Survey (HRMS): Historical perspectives
The modern era of the Search for Extraterrestrial Intelligence (SETI), which began with the paper of Cocconi and Morrison in 1959, reached a landmark with the inauguration of NASA's High Resolution
Infra-red astronomical background radiation
Measurements of astronomical background radiation are interesting because when they succeed they tell us the energy budget of the universe — at least that part of the budget that gives rise to
A search for Dyson spheres around late-type stars in the Iras catalog
Thirty years ago Dyson (1960) suggested searches for artificial stellar sources of infrared radiation. Dyson offers a scheme in which planets are broken down and reconstructed into a swarm of
The Search for Extraterrestrial Intelligence (SETI)
▪ Abstract The search for evidence of extraterrestrial intelligence is placed in the broader astronomical context of the search for extrasolar planets and biomarkers of primitive life elsewhere in ...
We report on a search for the presence of signals from extraterrestrial intelligence in the direction of the star system KIC 8462852. Observations were made at radio frequencies between 1 and 10 GHz
Transit detection of a ‘starshade’ at the inner lagrange point of an exoplanet
All water-covered rocky planets in the inner habitable zones of solar-type stars will inevitably experience a catastrophic runaway climate due to increasing stellar luminosity and limits to outgoing
A Search for Dyson Spheres Around Late-type Stars in the Solar Neighborhood.
. We continued our search for partial (incomplete) Dyson spheres associated with solar-type stars (spectral types F, G and K) within 25 pc of the Sun. No candidate objects were found in a total of
