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.

This program seeks to support innovative research that addresses key observational, theoretical, or technical questions in the field of technosignature science.   Eligibility: The program invites applications from Principal Investigators (PIs) in two distinct categories:

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.

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.
