The results are in from the first radio technosignature search involving pre-planned observations to synchronize with exoplanets during their transits.

A survey of a dozen exoplanets in the Kepler field has been performed using a Breakthrough Listen search code called “turboSETI” – an analysis tool.

The facility used in the search was the Robert C. Byrd Green Bank Telescope (GBT), based in West Virginia.

Thirteen citizen scientists volunteered their time to assist the science team with the further filtering of the turboSETI events.

A large list of “signals-of-interest” was reduced to two. However, these signals do not rise to the level of even “candidate” technosignature signals, the research team reports.

New ground

In the process, the research team hopes that the “new ground” that has been broken in radio technosignature parameter space “will be extended by more synchronized SETI searches in the future, across many more instruments and teams.”
