Technosignatures literature roundup
Reviewing the literature is an important part of the research process. It gives you a deeper knowledge of the field and prevents you re-inventing the wheel. ...
ETI does not exist
In a paper in 1980 [1], mathematical physicist Frank Tipler presented his argument that if extraterrestrial intelligent beings exist they would already be in...
Rationale for the water hole
Searching the ‘water hole’ for extraterrestrial signals had already been proposed nearly a decade earlier as a result of the 1971 Cyclops Project [1] but in ...
The Arecibo message of November, 1974
In 1974, the Arecibo Observatory became capable of transmitting radio signals at a maximum effective power that was twenty times the combined power of all po...
Why are extraterrestrials not on Earth?
After a series of papers on searching for communication signals from extraterrestrial civilisations [1,2,3,4,5,6,7,8,9], Michael Hart at NCAR in Boulder, Col...
A search strategy for finding extraterrestrial radio beacons
Building on the work of the Cyclops Project from 1971, Robert Dixon (a member of the signal processing group during the Cyclops Project) from Ohio State Univ...
Project Cyclops - Part II
This is my second post on Project Cyclops, a NASA study from 1971 that proposed a system for detecting extraterrestrial intelligence. These are my notes from...
Project Cyclops - Part I
The Cyclops study was a 1971 Summer Faulty Fellowship Program in Engineering Systems Design, funded by NASA in cooperation with the American Society for Engi...
Waiting times and longevity
Around the same time as several other papers proposing how best to conduct a search for extraterrrestrial intelligence [1,2,3,4,5], Sebastian von Hoerner pub...
The Drake equation
Following the first formal proposal in 1959 by Cocconi and Morrison [1] that humanity was capable of detecting interstellar communications from other intelli...
Kardashev classification scheme for extraterrestrial civilisations
In 1964, Nikolai Kardashev published a paper on how an extraterrestrial civilisation could maximise the information it transmitted to other stars [1]. He cal...
Interstellar communications by optical masers
In 1961, a paper published in Nature by Schwartz and Townes [1] was the first to propose that extraterrestrial intelligence may use an optical beam for commu...
Dyson spheres
I am currently reading the earliest SETI papers to get a better understanding of the core ideas in the field and how these have evolved. These are my notes o...
Project Ozma
In 1960, Frank Drake carried out the first experiment to detect radio signals from from an extraterrestrial intelligence (ETI) based on a strategy proposed b...
Communications from superior galactic communities
I recently read one of the first papers on the search for exoplanet technosignatures published in Nature in 1959 by Cocconi and Morrison [1]. You can see my ...
The search for interstellar communications
One of the first papers on the search for exoplanet technosignatures was published in Nature in 1959 by Cocconi and Morrison [1]. The authors assume that the...
What exoplanets can see technosignatures from Earth?
A recent paper in Nature [1] caught my attention because it reversed my perspective on the topic. Rather than focussing on whether we can see life elsewhere,...

Exoplanet biosignatures
In the last few decades we have discovered that Earth-like planets are common around other stars and many of these planets are likely to be habitable, i.e. o...
Recognising AI sentience
Right now the most advanced artificial intelligence is unaware of its existence and has no capacity to feel anything. It is based purely on a series of matri...
