NASA to fund SETI in its search for alien technosignatures

With the hype of the Dyson sphere ala Tabby's star, now dying down as it appears that interstellar dust is to blame for the dramatic dips in illumination.  Please refer to this link for articles.    NASA will begin funding SETI to recommence the search for advanced alien civilizations emitting technology byproducts.  The proposition of variations of technological signals range from extraterrestrial intelligence (ETI) shifting and utilizing stars to transfer advanced signals through the cosmos to massive structures like Dyson Spheres (alien structures that encases a star, tapping it for its power).  Or an ETI that has been able to alter Space and Time artificially for its advancement into the cosmos, which may or may not send out a conventional signal of detection -  such as the manipulation of reality.  Regardless, the science with its exotic speculations in searching for technosignatures will be an exciting time for astrophysics.

My 2017 book CATACLYSMAL discusses the possibilities of detection of exotic alien signals.

"Technosignatures are any signs of advanced technology in any one of various plausible forms. They’re analogous to biosignatures, which could be any element, isotope, molecule, or phenomenon that provides unmistakeable scientific evidence of past or present life on another world, whether intelligent or not. Technosignatures encompass a much larger conception of alien technology than just intelligent radio or light signals. They could also include such things as massive artificial structures or a planet’s atmosphere full of pollutants. In this way, the search for technosignatures extends beyond the more familiar SETI-type scenarios of looking for radio or light signals. The workshop was formed after Congress expressed a renewed interest in looking for intelligent alien life last April, urging NASA to expand on its search for technosignatures. The three main facets of the workshop included assessing the current state of the field of research, the most promising avenues of research in technosignatures and where investments could be made to advance the science. Another goal was to determine how NASA could best support the endeavor through partnerships with both private and philanthropic organizations." 

The hope in detecting advanced technological advanced civilizations:

"We really don’t know what the first evidence for an alien civilization may look like. It could indeed be radio or light waves, or something even more profound, like a Dyson sphere – a hypothesized massive artificial structure built around a star to harness all of its energy. Or maybe ruins of some now long-dead civilization on some distant planet or moon. Or perhaps intelligent, autonomous probes such as Bracewell probes sent into our solar system. As one example, Tabby’s Star (aka Boyajian’s Star) has generated a lot of excitement in recent years due to its bizarre episodes of sudden, rapid dimming – up to 22 percent – leading to speculation it may be home to a Dyson sphere or something similar. The sharp dimmings, as well as a much longer overall dimming pattern on the order of decades or centuries, are now thought to be caused by very fine dust, but the origin of the dust and how it’s replenished is still unknown."
