Did we just get a hello from aliens?

The chances of the only two civilisations in the entire galaxy happening to be neighbours, among 400bn stars, absolutely stretches the bounds of rationality.

I don't know. There could be factors that cause certain areas in space to just be more favorable to the creation of life, beyond just the planetary location relative to the star it orbits or what's on the planet surface. Some parts of the universe may have something that makes life more likely. No idea what that thing might be. There's a lot we don't know. I don't even know that there are expanding bands of space where these conditions may exist.

I think you're right on it not being likely on these two planets though.

The other option a ship and we caught a signal or maybe a probe sent to the system checking in? Other option is this alien race is long dead and we just happen to catch some automated signal from equipment that could be millions of years old.

Fun to speculate isnt it?

A ship, relay station, probe, galactic rest area. The sci-fi fan in me likes the idea of a fake distress beacon or an intergalactic tourism kiosk/visitor center.

You may have , but I did not.
I feel shunned.

OK here, thanks. Then I agree one needs to wait for further data to come out. I still believe the narrowband signal at that frequency smells suspiciously earthy.

As for the signal coming from an artificial satellite, I wouldn't discard it too soon. There are some 19,280 objects orbiting Sol-3 (including debris and SigInt nanosats disguised as debris). Let's wait and see.

I didn't realize that people still think that we are the only civilization in the universe? I also would wonder why they would communicate within the known electromagnetic spectrum....why in the hell is my post off center

I can answer your first question easy enough of course they do so far the only intelligent species we found have been on earth. So we coud be the anomoly and something very strange happened in the universe that has never happened before or again we just dont know. Though personally i think this is unlikely. Your second question technology has a certain way it advances the first thing any species with advanced technology would need to understand and use the em band. most technology is in some way related to the discovery of electricity and radio. So at some point they would have used radio same as we do even if they found a better form later. This is one of the mysteries if aliens are out there we should get a signal.

As for your 3rd question ill say

you forgot to do this!!!!!

This could be a hello that went wrong.

Well hopefully the human race will still be around when our weak ass radio signals get out to someone advanced enough to listen. As far as the only life forms scientists know about?.... I can buy that...but eventually they'll catch up

We’re still finding here on earth, that places that would be considered devoid of life, actually have life thriving.....our limited perception of where life can and will exist, is being proved to be wrong quite frequently.....

Yes life can be tough however intelligent life would have certain requirements. Because simple cell organisms would have to organize to create higher life forms. Im going to say i was excited to read this since everything i looked at indicated this has a real shot at being artificial and not from us.

How? We are so far apart that even light takes thousands of years to reach us

No, it takes 4 years. Hence 4 light years.

The Proxima Centauri signal is not likely to be from one of our own satellites. The radio frequency at which the signal was received-- 982.002 MegaHertz is not allocated for satellite use. It's an aeronautical communications and navigation band. However, the signal is not likely to be from one of our aircraft either. The signal persisted from one small point in the sky for three hours.

On the question-- why would an advanced species in space still use radio waves to communicate?

Even if they have something better than radio, if they wanted to communicate with us, radio would be the obvious choice. This may not even be a communications signal. Radio waves could be a byproduct of a more advanced technology, and we're just picking up their incidental noise. After all, we discovered fire hundreds of thousands of years ago, but still find some uses for it.

Correct!

I went back to wiki and checked the distance. It was my fault in translation. I was on the English wiki page checking the distance. To explain, my own language uses the dot (.) for separating thousands, English uses the dot for decimal. I should have seen it though because it's written in the thread somewhere, my fault.

I don't believe anything or anyone can travel through space that fast nor warp time/ dimensions etc etc but would be cool if they could. But doubt it.

Military satellites do not wait for civilians to allocate a frequency to use. They use whatever frequency they wish. Operational frequencies are not announced in advance. You use the most unexpected frequency in case you need it.

why would an advanced species in space still use radio waves to communicate?

Because they are communicating with a not-so-advanced civilisation. If you wish the less advanced civilisation to get your message you need to use the communication technology the less advanced civilisation uses.

However, I still believe the signal originates either in Earth (98% probability), or is due to a natural cosmic phenomena most likely having to du with the magnetosphere of the source planet, and the interaction with the interstellar. medium.

a reply to: Ross 54

You bring up an interesting point maybe it isn't a form of communication. And yes so far this seems like this is the best shot at actually being alien I dont think people are understanding that. I cant wait to see the paper sice the observation was also over several days.

a reply to: Direne

This is true and then we have multiple countries launching satellites even countries like South Korea. That is why you start checking orbits and it can be a painstaking process. So they will have to check for that to validate the signal

Well, I read one paper that using what's called solar sails they figured the trip would take 150 years.

You get halfway there and discover that there's nothing of interest. Oops.

In my opinion, there’s a pretty good chance it’s alien and artificial in nature, but not trying to “deliberately” communicate with us, it’s probably some kind of utility broadcast, beacon or coordinate calibration signal from ships/satellites/stations in that system. It may not even be native to the system in the first place:
