Scientists tighten the protocols for announcing any evidence of alien life

10:56 am

New protocols developed by Search for Extraterrestrial Intelligence (SETI) project and approved by the International Academy of Astronautics (IAA) now tighten significantly what the scientific community is expected to do if anyone detects evidence that might be extraterrestrial life.

You can read the full protocols here [pdf]. From the press release:

At the heart of the new rules is a reaffirmation of a core scientific principle: “extraordinary claims require extraordinary evidence.” Under the revised protocols, no public announcement should be made until a signal or artifact has been rigorously authenticated by independent organisations using different instrumentation.

“We do not shout “alien” the moment we see a strange blip,” Garrett added. “The scientific method demands we check, check again, and then ask others to check. Only when we have reached a consensus that a signal is credible do we bring it to the world.”

SETI’s press release notes this rule is necessary due to the modern nature of social media, which allows the wildest claims to be spread like poison almost immediately. As noted in this story, the new rules almost appear to be a direct slap at hack Harvard scientist Avi Loeb, who with both interstellar objects Oumuamua and Comet 3I/Atlas claimed evidence of alien technology when there was no evidence to say so.

The new rules also underline a second point: Under no condition will any scientist attempt to reply or contact any potential alien source. “The Declaration reaffirms the enduring principle that transmitting a response to an extraterrestrial intelligence is a decision that belongs to all of humanity and should only take place following international consultations, specifically through the United Nations.”

It will be impossible for the science community to enforce this rule, but by stating it they hope to encourage scientists to exercise more caution, and further ostracize those like Loeb who do not. I remain skeptical, especially because it will have no influence on government agencies like NASA, which love to scream “We have found alien biology!” at the slightest hint. Nor will it influence the public, which seems determined to accept such wild claims with no skepticism at all.

Astronomers look at one patch of sky and see no signs of alien life

9:12 am

Worlds without end: Using an Australian radio telescope array focused in the FM frequencies, astronomers did a seventeen hour sweep of one small of sky and found no evidence of alien transmissions.

“We observed the sky around the constellation of Vela for 17 hours, looking more than 100 times broader and deeper than ever before. With this dataset, we found no technosignatures—no sign of intelligent life.”

Professor Tingay said even though this was the broadest search yet, he was not shocked by the result. “As Douglas Adams noted in The Hitchhikers Guide to the Galaxy, ‘space is big, really big’. … And even though this was a really big study, the amount of space we looked at was the equivalent of trying to find something in the Earth’s oceans but only searching a volume of water equivalent to a large backyard swimming pool.

The radio array used in this search is only a small precursor to a much larger array, dubbed the Square Kilometer Array (SKA), which is under construction and many times more sensitive.
