http://www.businessinsider.com/ross-128-red-dwarf-radio-signals-mystery-2017-7Astronomers say they've detected "strange signals" coming from the direction of a small, dim star located about 11 light-years from Earth.
Researchers picked up the mysterious signals on May 12 using the Arecibo Observatory, a huge radio telescope built inside of a Puerto Rican sinkhole.
The radio signals appear to be coming from Ross 128, a red dwarf star that's not yet known to have any planets and is about 2,800 times dimmer than the sun. Abel Méndez, an astrobiologist at the University of Puerto Rico at Arecibo, said the star was observed for 10 minutes, during which time the signal was picked up and observed to be "almost periodic".
Méndez said it's extremely unlikely that intelligent extraterrestrial life is responsible, but noted that the possibility can't yet be ruled out.

(4,377 posts)But it does make me wonder when people ask 'if there is intelligent life, why haven't we seen it?!'. In the minute amount of time we've been looking, we have detected hundreds of unexplained signals from various parts of the galaxy. Sometimes earth based interference is responsible, sometimes its a space phenomena we don't understand yet, but really we have no idea about a lot of them. When we do eventually find other life, I suspect we'll look back at this time and all the stuff we tried to explain away and chuckle.

(12,660 posts)After all, we are in a rather unfashionable corner of a huge galaxy, and the amount of time we have been developed enough to consider the environment outside our immediate survival needs has been relatively small. Sort of like a late-night family arrival to live in a new neighborhood their 5-year old has never seen before. We're the 5-year old, and we've just finished breakfast and are looking out the kitchen window into our new back yard for the first time. We haven't even really walked out onto the front porch and checked out the neighborhood to see if there's any kids to play with...

If their planets did not have the right conditions to create hydrocarbon fuels then they never made it to advanced technology.
If their planets did have the right condition to create hydrocarbon fuels then they got advanced technology AND poisoned their atmosphere with CO2, destroying their civilization.
OR
If they got hydrocarbon fuels, they achieved high technology but when the hydrocarbons ran out their civilization collapsed for lack of energy.
Any way you cut it, civilization needs just the right conditions to arise, and those very conditions guarantee its collapse. In other words, civilization has a very short shelf life.

(21,506 posts)Based on our experience and knowledge. There is no way to know what is possible as far as energy or life to be honest.
Until recently we thought nothing could live in the environments like the volcanic vents at the bottom of the ocean yet life is there.
We do not know what we don't know is what I am getting at.

(7,911 posts)Can civilization exist in a volcanic vent at the bottom of the ocean?
That some form of life can exist does not imply that civilization can exist. Without habitat for living, and habit for growing food, the human animal goes extinct.

(38,317 posts)What makes us think we can recognize it in space?
Orcas, elephants, apes, ravens, parrots, etc. are all sentient intelligent beings, and our human so-called civilization is making life very difficult for all of them.

(3,581 posts)a satellite do this." ???
"Méndez thinks the signal is more likely from something humans put in space, perhaps a satellite that passed thousands of miles overhead.
"The field of view of [Arecibo] is wide enough, so there is the possibility that the signals were caused not by the star but another object in the line of sight," Méndez said, adding that "some communication satellites transmit in the frequencies we observed."
However, in a July 12 blog post about the mystery of Ross 128, he wrote that "we have never seen satellites emit bursts like that" and called the signals "very peculiar".
And then... this rather poorly written article... which was published about 3 hours ago (maybe around 11:00 a.m. EST on July 17) says the only way to be sure is to look at the star again.... which they'll start doing on JULY 16... which was yesterday.
So they should already have some preliminary results... not that you'd know it from this article.
Newsweek says they did conduct further tests yesterday and confirmed the data...http://www.newsweek.com/mystery-radio-signals-ross-128-star-637682 ... which, I assume means they detected the signals again.
They expect to have some definitive ideas about the source by the end of the week.

(65,076 posts)It's only 11 years away. That would put them about a 100 years behind earth, if they have transmissions strong enough to still be detectable from 64 trillion miles away.
Like the professor said, highly unlikely to be a non-natural phenomenon.

(869 posts)Two guys where working in an antenna shack trying to tune a receiver. They kept on getting this interference, this noise. So they decided it must be from the birdsh*t outside covering things up. So they went outside and got rid of the birdsh*t, but the interfering noise would not go away. Then suddenly they realized what they were hearing: The same thing that you see as black and white "snow" on your un-tuned TV - the remnant microwave noise left by the big bang!
The two guys were Arno Penzias and Robert Wilson. This happened in New Jersey in 1964. They shared the Nobel Prize.

(24,259 posts)This....
Or this....
The answer to the question, 'if there is intelligent life, why haven't we seen it?!' could be...
They don't think we're ready to see them yet
or
We have in the past but over time have come to see them as myths
or
We have (and still do) but we don't know it yet
or
All/None of the above.
I find the concept fascinating and hope if/when we do meet others they're friendly... and so are we. I'd love it if it happens while I'm still alive... well, unless they're awful or we're a meal... then I'll pass thanks.

(11,088 posts)It will take 11 years for them to get it and 11 years for us to get their signal, etc... that's gonna be a really long conversation!
