“The #SETI field has been starved of resources for so long that there is still a ton of work to do that could have been done decades ago. We can very quickly make a lot of progress in this field without a lot of effort.”

“It’s a great sign that the winds are changing at #NASA.” It is the first time NASA has given funding to a non-radio #technosignature search https://arstechnica.com/science/2020/07/the-real-science-behind-setis-hunt-for-intelligent-aliens/

The SETI Institute is excited to announce a new, first-of-its-kind #grants program aimed at advancing #technosignature science and technology. This program seeks to support innovative research that addresses key observational, theoretical, or technical questions in the field of technosignature science.

There are no nationality restrictions.

Applications for 2024 are due by 5PM Pacific Time on 31 July 2024. Successful applicants will be notified by 15 August 2024.

L'AI in aiuto per trovare forme di vita extraterrestri. Alla ricerca di tecnofirme extraterrestri, intervista a Stefano Cavuoti dell'Inaf di Napoli. Recentemente è stato pubblicato un report che fa il punto sulla ricerca della vita intelligente nell’universo.

If Astronomers See These Chemicals in a Planet's Atmosphere, There's Likely an Advanced Civilization There

Astronomers are searching for a biosignature to prove life on an exoplanet. This has been tricky since natural processes can produce many chemicals life generates. But there are chemicals that humanity has created due to an industrial process, which probably don't have a natural source. A recent paper suggests that nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) could be ideal technosignature gases, unable to form naturally but the result of industrial processes.

Do Advanced Civilizations Know We're Here?

Although humans have only sent a couple of tentative signals into space, many are concerned about the risks. Should we let alien civilizations know we're here? According to a new paper, humanity has already been broadcasting its existence for thousands of years, and civilizations with advanced enough technology should be able to observe us. It's science fiction to us, but megastructure space telescopes could have baselines of millions of kilometers, powerful enough to detect structures on the surface of Earth from thousands of light-years away.

@fraser #KesslerSyndrome seems like a good #technosignature and warning.

I do wonder if Kessler Syndrome would be a bit of an Anti-Pattern making near Earth space exponentially more difficult but opening up extra-solar travel, as we level up our shielding skills in kind.

Real-Time #Technosignature Strategies with #SN2023ixf: https://arxiv.org/abs/2306.03118 -> "Several technosignature techniques focus on historic events such as SN 1987A as the basis to search for coordinated signal broadcasts from extraterrestrial agents. The recently discovered SN 2023ixf in the spiral galaxy M101 is the nearest Type II supernova in over a decade, and will serve as an important benchmark event. [...] We are commencing a radio technosignature monitoring campaign". #SETI
