SETI: February 2020


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.
