Extraterrestrial as in "not of Earthly origin" — not as in space aliens.
Either way, I really hope that we establish contact with aliens in my lifetime. Hopefully they're chill, and like us lol.

Forget about why would they - they can't get here. The speed of light is too slow. They can't even detect earth exists much less there is life (dinosaurs). detectable signals won't reach then for a long time if they even can reach them.
The first commercial radio broadcast was transmitted on 2 November 1920
that means intentional radio signal was underway about 100 years ago.
so suppose that signal despite the "low" power is heard by someone that listens very closely. they tease it out of the noise, and right away know what it is, and try to send back.
at most, they are about 50 radio-years away, if thier signal reaches us now.
beyond that, no signal from earth has propagated that far.

Was this signal suspected to be from earth? Otherwise why point out the signal was “extraterrestrial origin after all”?
You need to rule out that you accidentally picked up some radio broadcast and state that otherwise anyone worth their salt will first ask, "Are you sure it didn't come from the local radio station?"

Any species that is advanced enough for interstellar communication will almost certainly be a highly aggressive apex species. You don't get to the top of the food chain by being nice, you get there by murdering all of the competition and plundering all of the resources. And if you were trying to be nice, someone else would have just wiped you out. The big question is if a species can eventually reach some point of co…

Be careful when training AI models on unknown signals, or uploading them publicly on the Internet to be picked up into training datasets. It might be an adversarial data poisoning attack, which is designed to bias the model into servicing the attacker. In this case, a superintelligent digital lifeform might be literally sending itself across space into every direction, and who knows what it does once it lands into a…
Only on HN can the top comment for a post about astronomy from the 1970s be about fucking 2025 era LLM concerns.

Which of our leaders do you hope their leaders are like?

Thanks... The fact that websites are now blocking Firefox by default as an "ad-blocker" is saddening.
I opened a firefox private window and navigated to it from the HN page, and got the adblocker popup.
Right now I have two tabs open in the same non-private window, one showing the adblocker popup and one not. In the one that's not I can view the whole page. Reloading in the one that is not showing the adblocker popup then showed it.
I navigated from HN in a non-private window and got the popup. So this seems to be referer constrained in some sense, not necessarily browser based. Hard to confirm.

Anyways What did you have for lunch? I heated up my leftovers in the microwave oven in the office. :)
