Astronomers find no signs of alien tech after scanning over 10 million stars

The study, published in Publications of the Astronomical Society of Australia on Monday, details a search for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), a collection of 4096 antennas planted in the red soil of Western Australia that detects radio signals from space. "They are little spider-like antennas that sit on the ground," explains Chenoa Tremblay, co-author on the study and astrophysicist with CSIRO, an Australian government scientific research organization.

Tremblay and co-author Stephen Tingay, from the International Centre for Radio Astronomy Research, used the MWA to listen out for "technosignatures," or evidence of alien technology, in a portion of the sky around the Vela constellation. Tremblay explains this region is scientifically interesting because a large number of stars have exploded and died, creating ideal conditions for new stars to form. The search for extraterrestrial life "piggy-backs" on other work studying this region to understand the life cycle of stars.

But how can you tell a radio signal from space is coming from an alien civilization? "Think of a car alarm when you leave your lights on, where there are a series of equally spaced 'ping' sounds," Tremblay says. The survey looks for a repeating ping that may be escaping noise from a planet or "a purpose built signal."

After listening to the Vela region for 17 hours, no unknown signals were detected. While the survey was able to capture over 10.3 million stellar sources and contained six known exoplanets (likely many more exist in the region), the team notes it was like trying to find something in an ocean, but only studying "a volume of water equivalent to a large backyard swimming pool."

And there's another big caveat.

"Looking for technosignatures is assuming that the civilisation have technology similar to our own," says Tremblay.

It is unlikely that they would fund evidence, even if there is life on other planets. As we have advanced, we’ve been going dark. We don’t shine our city lights in space as much as we used to and we are less dependent on radio waves as we have moved to moving all data through a closed internet system. Any advanced life will probably have gone dark even more than we have.

That’s because they all have shrinking technology which saves a lot of energy.

Aliens on stars? Kinda hot I should think.

Why go to all that expense and trouble? If you’re searching for evidence of aliens, just ask Hillary Clinton.

Does that mean they are not guilty?

My favorite quote on this subject (for those who may not be familiar with it):

To search expectantly for a radio signal from an extraterrestrial source is probably as culture-bound a presumption as to search the galaxy for a good Italian restaurant.

Or they may be communicating via quantum entanglement. Or maybe we were listening on AM and they were transmitting on FM(?)

It is probable that emitting electromagnetic waves as a method of communication will be a short-lived phenomenon as an advanced society creates some other, better method...possible something quantum in nature?

So all the civilizations scattered throughout the universe would emit such radiation in short one-time bursts.

We are probably not listening properly.

I see they are now calling it alien “technosignatures” because if they call it “intelligence” it could insult all the stupid aliens.

"assuming that the civilisation have technology similar to our own"

Our own technology is a brief snapshot of only a few decades compared to thousands of years of human civilization. Would civilizations thousands or millions of years ahead of us still be using radio waves for communication?

I wouldn’t expect the ‘scientists’ to say anything else.

Like any of us would trust anything a lizard alien would say.

10 million out of what...200 billion observable stars?

Sure, I'm convinced. Somebody has a low bar to jump or has a high opinion of themselves.

So, because they cannot find evidence that alien civilizations are using archaic Earth technology as the underpinnings of their advanced technologies, they assume they have not found evidence of advanced technologies.

How quaint!

The “scientists” have put a lead chain of dogma around our necks—they are definitely part of the problem and not part of the solution.

maybe they know something we don’t....
