I thought they just debunked this? Will have to find the report. I was sure Seth from SETI said so

I have not been keeping up with this for a while also..

But I know we have questioned Seth Shostaks opinions and comments on ET / UFO stuff on a few occasions..

If Brian Cox is suggesting that it maybe E.T associated then that maybe conflicting Seth if he claims to have debunked it..

and that makes it hard to wonder what to believe !  ???

as I thought usually both were likely to debunk E.T related Claims..

I thought they just debunked this? Will have to find the report. I was sure Seth from SETI said so

Two Articles relating to Seth...that seem conflicting at initial glance...maybe he came to a quick conclusion from his initial comments...

Alien Radio Signals Not Detected in Space Anomaly: SETI Institute


A star system that has been a source of speculation about extraterrestrial intelligence has offered only radio silence.

The Search for Extraterrestrial Intelligence Institute (SETI) has been monitoring an unusual light pattern in a star system for more than two weeks.

The system, KIC 8462852, also known as Tabby’s Star, has been under scrutiny since its unusual light fluctuation was discovered a few years back by users of the online astronomy crowdsourcing site Planet Hunters.

Situated 1,500 light years away between the Cygnus and Lyra constellations, light from the star system occasionally has dropped by 20%, according to data that was collected by NASA’s Kepler Telescope, which is on a mission to find Earth-like planets by looking for the periodic dimming of stars that might suggest a planet is passing by.

SETI Institute started investigating the star after learning that the Kepler team had vetted data showing there is an atypical light pattern coming from the region.

Using the Allen Telescope Array, which is comprised of a large number of small dishes used to monitor wavelengths, SETI Institute said it has not detected radio signals.

The telescope, located in the Cascade Mountains in California, was searching for two different types of radio signals — possible markers for technology.

The first type of radio signals, narrow-band signals, theoretically emit a “hailing signal” that a society would use if it wanted to announce its presence. They are most often sought in radio experiments, according to the SETI Institute. The second type — broadband signals — might be present if there was an ancient alien structure in the star system.

What the instituteis looking for are signals from transmitters such as from a television station or a radar, senior astronomer Seth Shostak told CNN. But so far they haven’t picked up anything from KIC 8462852.

But that doesn’t rule out intelligent life in the star system or other parts of the universe, Shostak said.

“There is estimated to be in our galaxy alone a trillion planets. And we can see 100 billion galaxies,” he said. “It’s believed that one in 10 stars may have a habitable world capable of supporting life. That’s a lot of real estate.”

Several theories have been offered up as explanations for the star’s aperiodic light variation.

In September, Yale postdoctoral astronomy fellow Tabetha Boyajian, who is on Planet Hunters’ advisory team, and other colleagues published an academic paper that theorized the light changes could be from comet fragments. However, Boyajian told CNN in October that future observations are still needed.

Other theories that have been tossed around by experts and astronomy novices include a swarm of comets, an undetected celestial phenomenon heading toward Earth, or the most attention-grabbing, an “alien megastructure,” a term coined by some internet users.

“The history of astronomy tells us that every time we thought we had found a phenomenon due to the activities of extraterrestrials, we were wrong,” Shostak said.

“But although it’s quite likely that this star’s strange behavior is due to nature, not aliens, it’s only prudent to check such things out.”

SETI plans to continue monitoring the star system.

World's top alien-hunter insists mysterious object spotted around a distant star COULD be the work of an extraterrestrial species

   
The world's top extraterrestrial-hunting astronomer has refused to rule out the possibility that an "alien megastructure" has been spotted orbiting around a distant star.

Seth Shostak, director of the Search for Extraterrestrial Intelligence (SETI) Institute, told Mirror Online his team has been "unable to disprove" the theory that a massive artificial structure is causing the mysterious light patterns spotted around a distant star.

Astronomers from SETI have spent two weeks analysing radio signals emanating from a star called KIC 8462852 .

But they have been unable to fully decide whether the strange "dimming" of the star's light is caused by some undiscovered natural phenomena, or the presence of a massive structure.

Some experts have suggested this mystery object could be a Dyson sphere - a huge solar power plant built around a star in order to harvest its energy.

"You could say that maybe this is a Dyson sphere built by an advanced society, a ring world or some other kind of megastructure," he told Mirror Online.

However, SETI has not been able to conclusively prove exactly what's going on around Tabby's Star, which Shostak fondly refers to as "Bob".

SETI astronomers used the Allen Telescope Array to search for radio waves aliens may have used as a "hailing signal".

They also looked for microwaves which could have been produced by "repair rockets" working to service the structure.

Although neither of these telltale signals have been found, Shostak said this could be down to the fact our tools just aren't sensitive enough to spot them.

"We didn't find the signals," he continued.

"But this is like peering down at Africa from the window of the International Space Station, failing to spot any large animals and then concluding there are no elephants on the whole continent.

"We can't yet rule out the possibility [that aliens built a huge structure around Tabby's Star]."

When pushed, Shostak said that he thought astronomers would eventually discover the dimming of the star is caused by a natural phenomenon.

He cited the example of pulsars, stars which send regular pulses of radio waves.

These were initially thought to be messages from alien civilisation when discovered in the 1960s, until they were fully explained in a Nobel Prize-winning piece of research.

"We should be careful not to throw out new ideas, one of which says the dimming of Tabby's Star is caused by an alien civilisation," he said.

"But my guess is that someone will have an idea of what causes this within the next year and they will prove it by looking at other stars and seeing the same thing happening."

Even if Tabby's Star was an alien stronghold, it would take thousands of years to communicate with them, because of the sheer distances involved.




Far out: Will aliens ever touch down on Earth?Far out: Will aliens ever touch down on Earth?
"It would be like putting a message in a bottle and tossing in the Atlantic," Shostak added.

We asked the alien hunter what he thought would happen if aliens spotted us first.

He said: "It would be like humans meeting trilobytes, because aliens could be billions of years more advanced than us.

"They could be aggressive - because aggression is favoured in a Darwinian system - but they could be peaceful.

"No one knows."



We come in peace: Or at least humans will be hoping that will be aliens attitudeWe come in peace: Or at least humans will be hoping that will be aliens attitude
Humans only began emitting powerful signals during the Second World War, he said, meaning it could take thousands of years before aliens spotted them and decided to come and pay us a visit.

"But who's to say they have a motivation to come here anyway?" Shostak asked.

"Earth probably doesn't have much they don't already have - except rock'n'roll."

Shostak has previously said that humans will find aliens within 2,000 years.

A new news article on this year old subject! Not much has changed -" Alien megastructure? 'Tabby's star' continues to baffle scientists"!!

This report does offer an interesting read about scientists  who are still trying to logically determine what is causing this star to dim! They are a bit perplexed!! :)

SPACE COM
By Mike Wall, Space.com Senior Writer  Published August 24, 2016
Nearly a year after first making headlines around the world, "Tabby's star" is still guarding its secrets.

In September 2015, a team led by Yale University astronomer Tabetha Boyajian announced that a star about 1,500 light-years from Earth called KIC 8462852 had dimmed oddly and dramatically several times over the past few years.

These dimming events, which were detected by NASA's planet-hunting Kepler space telescope, were far too substantial to be caused by an orbiting planet, scientists said. (In one case, 22 percent of the star's light was blocked. For comparison, when huge Jupiter crosses the sun's face, the result is a dimming of just 1 percent or so.) [13 Ways to Hunt Intelligent Alien Life]

Boyajian and her colleagues suggested that a cloud of fragmented comets or planetary building blocks might be responsible, but other researchers noted that the signal was also consistent with a possible "alien megastructure" — perhaps a giant swarm of energy-collecting solar panels known as a Dyson sphere.

Astronomers around the world soon began studying Tabby's star with a variety of instruments, and reanalyzing old observations of the object, in an attempt to figure out what, exactly, is going on. But they have yet to solve the puzzle.

"I'd say we have no good explanation right now for what's going on with Tabby's star," Jason Wright, an astronomer at Pennsylvania State University, said earlier this month during a talk at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "For now, it's still a mystery."

Another star has been found that similarly changes in light output!

Perhaps some "dark matter" passed in front of the star?

 Just a bump to keep this active and add a few musings and ponderings...

Actually locating a Dyson sphere or construct (or two) would really shake up the apple cart; for one, it would prove that life of some kind does exist beyond our little blue pebble

secondly, the sheer magnitude of creating such a structure boggles the mind totally; as an example, look at the novel "Ringworld" by Larry Niven; if located at the approximate "Goldilocks" distance from the Sun, 93,000,000 miles, it would be 292,159,500 miles in length in order to completely encircle the our sun; if it's width was 1/100th of the length it would be 2,921,595 miles;

this would require a tremendous amount of mass...

mind blown yet?
