Seeking out extraterrestrial technology… July 31, 2021

This from the Guardian during the week that:

A team of scientists will embark on a new international research project led by Harvard University to search for evidence of extraterrestrial life by looking for advanced technology it may leave behind.

The Galileo Project is led by the Harvard astronomy professor Avi Loeb. Loeb co-founded the project with Frank Laukien, CEO of Bruker Corporation, a Massachusetts-based manufacturer of scientific equipment.

 

“Given the recently discovered abundance of Earth-Sun systems, the Galileo Project is dedicated to the proposition that humans can no longer ignore the possible existence of Extraterrestrial Technological Civilizations (ETCs),” the team announced in a statement on Monday.

And that being the case?

Rather than searching for electromagnetic signals, the Galileo Project will search for physical objects associated with extraterrestrial technological equipment, also known as technosignatures.

The project will follow three major avenues of research: obtain high-resolution images of UAP through multi-detector sensors to discover their nature, search and conduct in-depth research on “Oumuamua-like” interstellar objects, and search for potential ETC satellites.

Ah… Oumuamua… That would be the object that entered the solar system in 2017 – an unusually shaped object at that.

According to the Galileo Project team, “Oumuamua turned out to have highly anomalous properties that defy well-understood natural explanations.” “We can only speculate … by stretching our imagination to ‘Oumuamua’ perhaps being an extraterrestrial technological object, similar to a very thin light-sail or communication dish,” it added.

That may be a bit of a stretch. While unusual it wasn’t so clearly so as to be artificial. Indeed wiki notes:

 

On 26 October 2018, theoretical physicist Avi Loeb and his postdoc Shmuel Bialy submitted a paper exploring the possibility of ʻOumuamua being an artificial thin solar sail[120][121]accelerated by solar radiation pressure, in an effort to help explain the object’s comet-like non-gravitational acceleration.[64][65][122] Other scientists have stated that the available evidence is insufficient to consider such a premise,[123][124][125] and that a tumbling solar sail would not be able to accelerate.[126] In response, Loeb wrote an article detailing six anomalous properties[which?] of ʻOumuamua that make it unusual, unlike any comets or asteroids seen before.[127][128] A subsequent report on observations by the Spitzer Space Telescope set a tight limit on cometary outgassing of any carbon-based molecules and indicated that ʻOumuamua is at least ten times more shiny than a typical comet.[129] The alien object hypothesis is considered unlikely by many experts.[130][131]

 

Of course, it could be an alien probe/craft or whatever. And the broader Galileo Project approach seems reasonably robust  – and what an interesting point the following is:

“We want to clear the fog through a transparent and scientific analysis by assembling our own data, not data based on government-owned sensors, because most of that data is classified,” Laukien said.

Currently, the team is selecting instruments it plans to purchase and is planning to set up tens of telescope systems globally. Each system will consist of approximately two 25-centimeter (10in) telescopes with a camera suitable to detect objects of interest, connected to a computer system that will filter out data.
