Astronomers Get Serious About Alien Technosignatures
The hunt for optical technological signatures of extraterrestrial civilizations has finally gone mainstream. For nearly six decades, a small, but gung-ho group of scientists have been looking for radio and optical signals from space aliens. Now, the Search for Extraterrestrial Intelligence (SETI) has been adopted by a more mainstream group of researchers eager to look for optical technosignatures of otherworldly civilizations. At the recent AbSciCon 2019 conference on astrobiology in Bellevue, Washington, the topic was very well represented in a series of oral presentations.
