SETI: February 2020


Data from a massive search for cosmic radio emission released Feb 14. by the Breakthrough Listen Initiative--the most comprehensive survey yet of radio emissions from the Milky Way--has allowed astronomers to look for technological signatures of extraterrestrial civilizations that might be looking for us.

We report on a search for artificial narrowband signals of 20 stars within the restricted Earth Transit Zone as a part of the ten-year Breakthrough Listen (BL) search for extraterrestrial intelligence.

Emerging technologies and new strategies are opening a revitalized era in the search for extraterrestrial intelligence (SETI).

The Breakthrough Listen Initiative today (Friday, Feb. 14) released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations.

The Search for Extraterrestrial Intelligence (SETI) attempts to address the possibility of the presence of technological civilizations beyond the Earth.

Low mass X-ray binaries (LMXBs) containing neutron stars are both extremely luminous and compact, emitting up to ~10^6 L_sun within a kilometer-scale boundary layer. This combination allows for easy modulation, motivating X-ray SETI.
