SETI Tactics On FAST Fractality

We combed the Koch snowflake fractal antennae in calibre design of Five-hundred-meter Aperture Spherical radio Telescope (FAST), building a conjecture of a second-order fractal primary reflectors to optimize the orientated sensitivity of the telescope.

The modern search for extraterrestrial intelligence (SETI) began with the seminal publications of Cocconi & Morrison (1959) and Schwartz & Townes (1961), who proposed to search for narrow-band signals in the radio spectrum, and for optical laser pulses.

A researcher at the Instituto de Astrofísica de Canarias (IAC) is the lead author of a study with proposals for "technosignatures" -evidence for the use of technology or industrial activity in other parts of the Universe- for future NASA missions.

It is well-known that the chances of success of SETI depend on the longevity of technological civilizations or, more broadly, on the duration of the signs of their existence, or technosignatures.

New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet science and observing capabilities in recent years.

If there's an advanced extraterrestrial civilization inhabiting a nearby star system, we might be able to detect it using its own atmospheric pollution, according to new NASA research.

Nitrogen dioxide (NO2) on Earth today has biogenic and anthropogenic sources. During the COVID-19 pandemic, observations of global NO2 emissions have shown significant decrease in urban areas.

A search for laser light from Proxima Centauri was performed, including 107 high-resolution, optical spectra obtained between 2004 and 2019. Among them, 57 spectra contain multiple, confined spectral combs, each consisting of 10 closely-spaced frequencies of light.

New research from The University of Manchester suggests using a strategy linked to cooperative game playing known as 'game theory' in order to maximise the potential of finding intelligent alien life.

Exoplanetary systems are prime targets for the Search for Extraterrestrial Intelligence (SETI). With the recent uptick in the identification of candidate and confirmed exoplanets through the work of missions like the Transiting Exoplanet Survey Satellite (TESS), we are beginning to understand that Earth-like planets are common.
