This is interesting on its own:

NASA and the Search for Technosignatures: A Report from the NASA Technosignatures Workshop

Link to PDF file HERE.

In short: technosignatures are “stuff produced by technology.” More specifically, *alien* technology. So… starships, space probes, debris, laser beams, radio signals, Michael Jackson. This workshop is about the *search* for such things, evidence that aliens are out there, or were near here. They could be detected as close as sitting on the surface of the Earth, to detected lightyears away through optical or radio telescopes. It’s a reasonable task for NASA to look for this sort of thing, and to make plans on how to analyze them if they are found. The report summarizes a number of detection strategies, and provides a lot of interesting information about just what some of the products of advanced civilizations might looks like – everything from altered climates to Dyson spheres – from lightyears off.

It’s all perfectly reasonable.

But then…

Ugh.
