From Andreas - “Although the likelihood of discovering simple (biosignatures) or intelligent (technosignatures) life in our galaxy is unknown, a true positive detection is expected to significantly impact society through amplification by social media & the news media.
Research in risk & science communication shows that risk perceptions and public representations of astrobiology/SETI play vital roles in how these events unfold in the public sphere.

A new study scanned the Galactic Center at 150 MHz for alien signals—but once again, silence. If life is out there, why aren’t they talking? Or are we just listening on the wrong frequencies?

Could a twin Earth detect #Earth?Researchers used a theoretical, modeling-based method, and this study is the first to analyze multiple types of #technosignatures together rather than separately. The findings revealed that radio signals, such as planetary radar emissions from the former Arecibo Observatory, are Earth’s most detectable technosignatures, potentially visible from up to 12,000 light-years away.

Fun couple of days at the #BreakthroughListen meeting at #SKAO this week, hearing about all the ways astronomers are searching for evidence of #technosignatures 👽 🛸 (we haven’t found any yet, but there are some really clever search techniques). The best bit? The final day pick n mix selection included UFOs…! 😁

A former #NASA official says unidentified anomalous phenomena, or #UAP - the things better known as #UFOs - could be officially added to the space agency's research portfolio using the same strategy that he used to add the search for #technosignatures (including #SETI). This was one of the fascinating sessions at the #SciWri23 meeting in Colorado. https://www.universetoday.com/163581/nasa-next-ufo-uap-research/ #Space #Aliens

On Detecting Interstellar Scintillation in Narrowband Radio #SETI
The Astrophysical Journal, Volume 952, Number 1"radio frequency scattering effects,…spectra broadening, could imprint on extra-solar narrowband signals, altering them enough to be resolved and distinguished from terrestrial radio frequency interference (RFI). A signal filter based on #astrophysical properties would be an important tool…for evaluating candidate #technosignatures."

One way to study #MachineIntelligence is with more powerful #space #telescopes.
Even though we have yet to find examples of other civilizations out there, they certainly are there to be found. There is a growing consensus among scientists that extraterrestrial #technosignatures might well be more common than #biosignatures. After all, machines can prosper in all the wide space while biospheres require very specific circumstances.
#Biospheres are also very difficult to detect.
Even if planetary life was fleeting and oft erased by asteroids and gamma ray bursts, once autonomous machines start replicating in space they become practically invulnerable to #extinction.
Why haven't we found examples yet? Well, we don't quite know what to look for. If you look at astronomy as a field, we almost routinely find things which have no convincing explanations. As these observations often do not repeat, we just shrug and move on.
Most search for extraterrestrial intelligence so far has focused on planets and biospheres, and only recently we have been starting to look more seriously with a wider focus.
Regardless, the space is huge, it extends in the cube of the distance, and we haven't really scratched the surface of it yet.
We might well gain crucial insights into machine intelligence with one of the next generation space telescopes instead of through our own experimentation. At least we know that paperclip maximization doesn't really seem like a thing, that we would have noticed already.
