Giuseppe Cocconi and Philip Morrison\u2019s proposed detecting deliberate radio signals (&#8220;communication SETI&#8221;), while Freeman Dyson (&#8220;artifact SETI&#8221;), proposed detecting the inevitable effects of massive energy supplies and artifacts on their surroundings. While communication SETI has now had several career-long practitioners, artifact SETI has, until recently, not been a vibrant field of study.<\/em><\/p>\n<p><em>The launch of the Kepler and WISE satellites have greatly renewed interest in the field, however, and the recent Breakthrough Listen Initiative has provided new motivation for finding good targets for communication SETI. Dr. Wright will discuss the progress of the \u011c Search for Extraterrestrial Civilizations with Large Energy Supplies, including its justification and motivation, waste heat search strategy and first results, and the framework for a search for megastructures via transit light curves. The last of these led to the identification of KIC 8462852 (a.k.a. &#8220;Tabby&#8217;s Star&#8221;) as a candidate ETI host. This star, discovered by Boyajian and the <a href=\"https:\/\/www.planethunters.org\/\" target=\"_blank\">Zooniverse Planet Hunters<\/a>, exhibits several apparently unique and so-far unexplained photometric properties, and continues to confound natural explanation.<\/em><\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"1600\" height=\"900\" src=\"https:\/\/www.youtube.com\/embed\/XEDR-G2EDRM?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I\u00a0posted recently\u00a0about\u00a0 Tabby\u2019s Star, also known as\u00a0the \u201cAlien Megastructure Star\u201d. \u00a0In the SETI Institute seminar video below, Prof. Jason Wright of\u00a0Penn State University reviews what&#8217;s known about the star and discusses the latest findings on\u00a0the star in the context of searches for &#8220;Extraterrestrial Civilizations with Large Energy Supplies&#8221;.
