This month, two teams of astronomers announced the potential discovery of Dyson spheres in our galaxy. But have we truly found indicators of highly advanced civilizations? Join Dr. Franck Marchis and Dr. Lauren Sgro as they delve into these groundbreaking findings and their implications for SETI research.
Avi Loeb is far from alone in seeking signs of life beyond our pale blue dot. Bioastronomers are using observatories like NASA's James Webb Telescope to search for chemical signatures of life on exoplanets — planets outside of our solar system. NASA is also sending probes to see if there are signs of life within the solar system. Other scientists are looking for "techno signatures," such as radio signals that could lead to other civilizations.
An updated and expanded guide to science fiction with reasonable astronomy, compiled by astronomy educator Andrew Fraknoi, is now available free online. The 23-page guide is organized by topic; so, for example, all the stories that feature reasonable depictions of black holes are in one place. Some 44 astronomy (and related physics) topics are covered.
Only one day remains in 2023—which means time is running short for you to become one of the 100 people needed to help us meet our match challenge and continue the search for life beyond Earth with a year-end contribution!
Any donation made to the SETI Institute before midnight on December 31 will be doubled up to $10,000, so your support will go twice as far in helping answer one of the most profound questions of all time: are we alone?
