New research suggests the closest technological civilization in the Milky Way could be about 33,000 light years from Earth. For such a society to coexist with humanity, it would need to have endured for at least 280,000 years. The findings, presented at a joint meeting in Helsinki, underscore the rarity of extraterrestrial intelligence.
