Space aliens are still kinda the best explanation. It's extremely inconclusive, and it's entirely possible that we'll discover some new natural phenomenon to explain it instead, but for now there's not really any known alternative.

Most things aren't known. The lack of a known alternative is hardly evidence of anything in this domain.

There was something a few years ago saying it was likely hydrogen getting lased or something by starlight and emitting the signal.

The recent article on the WOW signal is "Arecibo Wow! II: Revised Properties of the Wow! Signal from Archival Ohio SETI Data" https://arxiv.org/abs/2508.10657 by Abel Méndez, Kevin N. Ortiz Ceballos, Jorge I. Zuluaga (and many others)

This is a follow up to a September 2024 paper (the article you link is November 2024)... "Arecibo Wow! I: An Astrophysical Explanation for the Wow! Signal" by Abel Méndez, Kevin Ortiz Ceballos, Jorge I. Zuluaga (just those three).

>but for now there's not really any known alternative

The research in the article does suggest a plausible alternative

That's like saying God is the best explanation for any newly described natural phenomenon.

May I interest you in "Calculating God" by Robert J. Sawyer?

How? We don't know gods exist. We know beings with technology and agency living on planets in space exist. There seems nothing at all similar between the two explanations.

[fallat]

God is an extraterrestial or not? :)

[zamalek]

It could just as easily be known, or unknown, physics.

[krapp]

Space aliens are also not a known alternative.

[ghurtado]

Not really.

There are many, many cosmic processes that we don't know the first thing about.

At one point, we didn't know what a pulsar was, and a fair amount of people probably thought it was an alien signal.

Human History is littered with examples of attribution of the unexplained to aliens.

So far, non alien explanations have been found for all of them, except possibly this one.

Does it warrant further study? Absolutely. Is it likely to be aliens? Statistically, no.

[cmrdporcupine]

Indeed. Human history is riddled with anthropomorphism and people here trying to argue for more of it.

We probably wouldn't even recognize real aliens because we'd be too busy looking for our own reflection in the sky.
