SETI Post-Detection Hubsetihub

The project includes cases such as exoplanet , phosphine on , Tabby's Star, , and . Each video is currently being coded in terms of risk and benefit narratives, sources, science actors and evaluations, and frames of (un)certainty.

The group is using computational methods to analyze thousands of user comments on public videos to investigate reactions to discovery in terms of sentiment and other aspects.

Artist's impression showing the planet K2-18b. K2-18b is a super-Earth exoplanet known to host both water and temperatures that could support life.

On the right side of the image, a huge blue planet fills nearly half the frame: swirling cloud layers cover the planet's surface that looks to be gaseous or ice-dominated.

In the lower left corner, a small orange star is surrounded by dark sky. Near the star, a much smaller planet appears as a dim, distant silhouette.

This artwork represents the K2-18 system, where K2-18b orbits a cool red dwarf star. University College London researchers used archive data from 2016 and 2017 captured by the NASA's Hubble Space Telescope and developed open-source algorithms to analyze the starlight filtered through K2-18b's atmosphere. The results revealed the molecular signature of water vapor, also indicating the presence of hydrogen and helium in the planet's atmosphere.

What scientific methods can approach questions of future discovery?

Hub member and risk-communication scholar Andreas Schwarz and students at Ilmenau University of Technology are analyzing YouTube content about post-detection claims with data scientist Anamaria Berea (George Mason University) and the Hub at St Andrews.

🌍 How do you think the world would react if there was a confirmed discovery of extraterrestrial intelligence?

Would it spark global unity, scientific renaissance, or fear and skepticism? Would the impact last or slowly fade away? Would it change anything if the discovery was within our own Solar System?

📯 Exciting news for the #UKSRN #astrodon account.

The #SETI Post-Detection Hub launched on 2nd Nov 2022 at the #University of #StAndrews. news.st-andrews.ac.uk/archive/

Will this #planet ever receive a #message from #extraterrestrial intelligence? Is #earth ready for #contact if it does?

The #hub connects #research across the #sciences & #humanities. If you're a researcher interested in #PostDetection & the #search for #ET, #xenolinguistics #spacestudies #contact, say hello đź‘‹ seti.wp.st-andrews.ac.uk
