SETI: October 2020


The nearby star ϵ Eridani has been a frequent target of radio surveys for stellar emission and extraterrestial intelligence. Using deep 2−4 GHz observations with the Very Large Array, we have uncovered a 29 μJy compact, steady continuum radio source coincident with ϵ Eridani to within 0.06 arcseconds (≲2σ; 0.2 au at the distance of the star).

As our ability to undertake more powerful Searches for Extraterrestrial Intelligence (SETI) grows, so does interest in the more controversial endeavour of Messaging Extraterrestrial Intelligence (METI).
