Some great #SETI talks at the #breakthroughinstitute Breakthrough Discuss 2023. Mind-blowing to hear of a mission proposal to survey the whole #lunar surface to sub-metre precision to look for evidence of #technosignatures (alien artefacts). Onboard #MachineLearning would be used to work out what bits of the surface are "out of the ordinary". Tests using existing lower resolution data are already able to successfully identify the #Apollo lunar landing sites, without any prior training. Amazing!
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
TODAY#ASignInSpace online reception with artist and researcher Daniela de Paulis and interdisciplinary team.
A Sign in Space - https://asignin.space - is a bold and creative #PostDetection experiment that simulates an extraterrestrial message and invites responses from the public.

#Reuters 📆 May 31, 2023 #SETI : The #scientists in the various monitoring efforts passively #scan 📡 for signals of #alien 👽 beings and do not actively #send their own signals advertising our presence on #Earth.
Earth's outgoing radio transmission (focus: cellular phone network broadcasts) modelled from 3 stellar viewing points: HD 95735, Barnard’s star, and Alpha Centauri A.
If Aliens were out there and using a telescope like the Green Bank telescope, then they still wouldn't detect these signals from Earth, out to 10 light-years.
But what I am finding interesting, is that the modelling takes into account Earth's rotation, and so mobile towers on different continents come in and out of view - so you could sorta 'map' where civilisation resides if you had technology sensitive enough to make the detections.
A blueprint of where our populations are, for the aliens, basically. But also, the Sun is radio loud when active, so kinda drowns us out, too (unless the aliens have a very big interferometer and can resolve the Earth and Sun individually).
One of the world’s most powerful #RadioTelescope arrays is joining the hunt for signals from other galactic civilizations: https://www.seti.org/press-release/massive-radio-array-search-extraterrestrial-signals-other-civilizations - the National Science Foundation’s Karl G. Jansky Very Large Array (#VLA), situated about 50 miles west of Socorro, New Mexico, is collecting data that scientists will analyze for the type of emissions that only artificial transmitters make, signals that would betray the existence of a technically accomplished society. #SETI
