Is Something in Space Talking to Us?

SETI Astronomer, Seth Shostak, goes over instances in history when aliens may have tried to contact us.

We need a "quantum tunner" like we have radio tunners but for tunning real-time entanglement communication independently from where it is, any direction any distance. RF is too slow to talk outside our solar system (where we mostly find a reply)

Life In Space: From Europa to Aliens

As we search for highly evolved civilizations far out in the universe, what do we expect their biological or technological signatures to look like? Would aliens ever let us know they exist? Would we even recognize civilizations far more advanced than our own?

SETI (Search for Extraterrestrial Intelligence) Institute astronomers Dr. Jill Tarter and Dr. Franck Marchis, and Jet Propulsion Laboratory Europa Project Staff Scientist and Science Communications Lead Dr. Cynthia Phillips engage in a far-reaching discussion of the possibilities of life beyond Earth. The talk is moderated by Charles Lindsay, interdisciplinary artist and director of the SETI Institute’s artist in residence program.

Recorded November 9, 2016 at Yerba Buena Center for the Arts

In conjunction with the exhibition Space Program: Europa by Tom Sachs.

Are humans the real ancient aliens?

by Seth Shostak

Harvard Astronomer Avi Loeb and his colleagues in the U.K. have argued that the halcyon days for life are still to come. It's not even morning in the universe; it's pre-dawn. Biology may erupt like weeds on an untold number of worlds, but if so, the infestation will take place tens of billions of years in the future.

The argument is straightforward: The longer you wait, the more examples of biology you'll have. But stars like our Sun can't wait too long: there's a relatively short opportunity to strut and fret. In 10 billion years, they've run through their easily accessible fuel, and are headed out the door.

But consider red dwarf stars, the runts of the universe. Their masses are considerably less than Sol's, which means they burn more slowly. The consequence? Red dwarfs with one-tenth the mass of the Sun have lifespans that are up to a thousand times longer.

All else being equal, that would give red dwarfs a thousand times the probability of eventually using its energy to host a world with life. Clearly, it's most probable that this life would arise not when these stars are still young — which they all are now — but instead during their long adulthood. In other words, the red dwarfs are just getting started, and their biologically fecund years are still ahead.

A recent research paper suggests that terrestrial-style biology may be rare, and Earth may be among the first examples of a planet able to sustain life in the cosmos.

Happy birthday to the Drake Equation, which is now 55 years old!

Drake came up with a simple equation, a string of seven factors that, when multiplied together, provide an estimate of the number of galactic, transmitting societies. If this number was very small, then SETI made no sense. If it was large, then there was a chance of hearing something. This equation solved his agenda problem.

No “official” estimates for the terms of Drake’s equation were produced by the conference, although Drake himself has suggested that the number of galactic societies that are on the air might be ten thousand. But despite the fact that his formulation is hard to evaluate (we still don’t know the values of many terms), it has become a widely accepted tool for considering the question of extraterrestrial intelligence.

Indeed, 55 years after Frank Drake first wrote this equation on a chalkboard, it has arguably attained the status of the second most famous formula in science (after Einstein’s E=mc2), and can be found in every astronomy textbook. It is also a guide for the research programs of the SETI Institute, each of which can be tied to a term in the equation.

By Seth Shostak, Senior Astronomer. Frank Drake had a problem. It was the fall of 1961, a year after his pioneering SETI experiment: Project Osma. Using an 85-foot antenna in Green Bank, West Virginia, Drake had unfurled the intriguing possibility that we might find proof of intelligent beings ...

"Drake equation“ is not scientifically rigorous and is no better than a wild guess

Why only Americans Are interested in the hunt for alien life

Bottom line? Today, SETI is solely an American enterprise. And even then, it's pretty minimal. SETI is not on the back burner … it's on the pilot light. The total number of researchers can be tallied on your extremities, and there's essentially no government funding. The effort is tiny, but at least there's effort.

So what's going on here? If a dozen other countries have the telescopes, the money, and the research horsepower to search for cosmic company, why is this extraordinarily profound quest confined to the U.S.?

An obvious answer would be to suggest that the problem is too open-ended. It's possible that even if we poured huge amounts of money into the search, nothing would be found. Bookies can't give sensible odds for success, even to those willing to gamble. Other countries are just being practical.

+John Lawrence john ! - it doesn't matter if you don't want to see the way i see it or what i know .
But to add to it . I know now 100% that they are not military stellarship .
And i don't believe that any country have this technology or know all about it .
Was about 11 pm when one ship right in front of me showed to me they speed . I don't know why they did it in front of me but it was spectacular .
So you can joke . I am not going to lie .
All i am saying is that this technique and technology is not right . But is you really want to spend money and see and hear them . Get your self a soner . This way you can even see them - communicate with them or learn how to to do that .
Think I am wrong !

Need to calculate how complex life is. How rare planets like earth actually are first. Life is not guaranteed to be common at all.

Fraser Cain of Universe Today asks in this video: What If We Do Find Aliens?

We've been so busy wondering how we'll find aliens that we never stopped to consider what we'll do if we actually encounter them. How does an alien discovery get communicated to the media? Who's responsible to craft a response?

Unexpected 'Arrival': Humanity's Not Ready for Aliens

The prospect of aliens visiting Earth has been percolating through human thought for decades, thanks to countless sci-fi books and movies, such as the newly released film "Arrival." But it's still not clear how we would deal with the real thing.

Astronomers have drawn up a series of recommended actions to be taken after the detection of a signal from a faraway alien civilization, but it seems that no such effort has been made with regard to E.T.'s arrival here, said veteran alien hunter Seth Shostak.

"I don't know of any protocol if they land," said Shostak, a senior astronomer at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California.

"I've never heard of any such thing, and I'd be surprised if there was one," Shostak said. "But who knows what's in the bowels of the Pentagon?"
