Is Earth being contacted by ALIENS? Mystery radio signals coming from a sun-like star baffle scientists
  • The signals seem to be coming from a sun-like star known as HD 164595
  • The star is 95 light years away and may have undiscovered planets in orbit
  • Scientists say signals may simply be the result of a natural phenomenon
  • One possibility is 'microlensing' in which the star's gravity focuses signals coming from farther away

A spike in radio signals coming from the direction of a sun-like star has excited astronomers.

The signals seem to be originating from a sun-like star known as HD 164595 in the constellation Hercules, around 95 light years away.

Scientists suggest they are likely to be the result of a natural phenomenon, such as 'microlensing', in which the star's gravity strengthens and focus signals from elsewhere.

But astronomers have also asked Seti (Search for Extraterrestrial Intelligence) to take a closer look at whether they could be a message from ET.

WHAT ELSE COULD IT BE?
A star or planet can act as a cosmic lens to magnify and brighten a more distant star or signal lined up behind it.

That's because the gravitational field of the foreground star bends and focuses light, like a glass lens bending and focusing starlight in a telescope.

Albert Einstein predicted this effect in his theory of general relativity and confirmed it with our sun.

Scientists believe the latest signals could be the result of this microlensing effect in which the star's gravity strengthens and focus signals from farther away.

SETI will track HD 164595 tonight using the Allen Telescope Array in northern California and the Boquete Optical SETI Observatory in Panama.

According to a report by Paul Gilster at Centauri Dreams, the signal was first detected on May 15 last year by the RATAN-600 radio telescope in Zelenchukskaya.

HD 164595 is interesting to scientists because it's a sun-like star with at least one 'warm Neptune' planet in orbit.

Its average temperature is 12 Kelvin hotter than the sun and is around 100 million years younger than our star.

Scientists say there may still be other planets undetected around HD 164595.

'No one is claiming that this is the work of an extraterrestrial civilisation, but it is certainly worth further study,' writes Gilster.

'Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilisation.'

IS IT A GOOD IDEA TO GET IN CONTACT WITH ALIENS?
If there are any intelligent alien life forms out there, Stephen Hawking thinks we're playing a dangerous game by trying to contact them.

The physicist believes if aliens discovered Earth, they are likely to want to conquer and colonise our planet.

'If aliens visit us, the outcome could be much like when Columbus landed in America, which didn't turn out well for the Native Americans,' he said in an interview.

But co-founder and former director of the Seti Institute, Jill Tarter, doesn't think this will be the case.

She argues any aliens who have managed to travel across the universe will be sophisticated enough to be friendly and peaceful.

'The idea of a civilisation which has managed to survive far longer than we have...and the fact that that technology remains an aggressive one, to me, doesn't make sense,' she said.

'If it were a narrow beam signal focused on our solar system, it would be of a power available to a Kardashev Type I civilisation.'

The Kardashev scale is a way of measuring an alien society's technological advancement based upon how much energy it has at its disposal.

A Type I civilisation is given to species who have been able to harness all the energy that is available from a nearby star, gathering and storing it to meet its population's demands.

A Type II civilisation is much more advanced and can harness the power of their entire star.

Type III is a species that has been able to master everything having to do with energy. Earth doesn't feature on the scale.

'This is a bit of a puzzling story, as the Russians found this signal a year ago or so, but just didn't let others know,' Seth Shostak, senior astronomer at the SETI Institute told GeekWire.

'That's not good policy, as what you really want is confirmation at another telescope, but… Is it real?

'The signal may be real, but I suspect it's not ET. There are other possibilities for a wide-band signal such as this, and they're caused by natural sources (or even terrestrial interference).'

The researchers who discovered the signals at the Russian Academy of Sciences' Special Astrophysical Observatory say 'permanent monitoring' of HD 164595 is needed.

The signal will be discussed at next month's International Astronautical Congress being held in Mexico.

jcowboy I just watched a video on this exact thing and followed it up with a video about the dangers of contacting extraterrestrial life, most of which was based on Hawking's beliefs. Its interesting that you posted this as it was going through my mind while I was reading down this thread! The video I watched what about 20 minutes long, I will see if I can find it again.

Strange signals from 234 stars could be ET – or human error



Twinkle, twinkle?
Sloan Digital Sky Survey

By Shannon Hall

It’s a bold claim. Two astronomers think they have spotted messages from not just one extraterrestrial civilisation, but 234 of them. The news has sparked a lively debate in the field as other astronomers think the claim is premature and are working fast to get to the bottom of the signals.

In 2012, Ermanno Borra at Laval University in Quebec suggested that an extraterrestrial civilisation might use a laser as a means of interstellar communication. If the little green men simply flashed a laser toward the Earth like a strobe light, we would see periodic bursts of light hidden in the spectrum of their host star. They would be incredibly faint and rapid, but a mathematical analysis could uncover them.

“The kind of energy needed to generate this signal is not crazy,” says Borra. In fact, Borra showed that technology we have on Earth today – specifically the Helios laser at the Lawrence Livermore National Laboratory – could generate that kind of signal, should we want to reveal ourselves to the cosmos.




.

With this in mind, Borra’s graduate student Eric Trottier combed through 2.5 million stars recorded by the Sloan Digital Sky Survey in search of such a signal. He found it, down to the exact shape, in 234 stars.

The overwhelming majority of those stars are in the same spectral class as the sun, which Borra says supports his hypothesis that this signature must be the result of extraterrestrial intelligent life. And with the data in hand, he thinks that 234 distinct civilisations are beaming pulses of the same periodicity (roughly 1.65 picoseconds) toward the Earth.

Borra and Trottier ruled out other possible explanations for the pattern, like rapid pulsations in the atmospheres of the stars themselves and rotational transitions in molecules. “We have to follow a scientific approach, not an emotional one,” says Borra. “But intuitively – my emotion speaks now – I strongly suspect that it’s an ETI signal.”










Extraordinary claims
Other astronomers think that Borra’s intuition might have run away with him.

“They don’t consider every natural possibility and jump prematurely to the supernatural – so to speak – conclusion,” says Peter Plavchan at Missouri State University in Springfield. “I think it’s way too premature to do that.”

“There is perhaps no bolder claim that one could make in observational astrophysics than the discovery of intelligent life beyond the Earth,” says Andrew Siemion, the director of the SETI Research Centre at the University of California Berkeley. “It’s an incredibly profound subject—and of course that’s why many of us devote our lives to the field and put so much energy into trying to answer these questions. But you can’t make such definitive statements about detections unless you’ve exhausted every possible means of follow-up.”

So that’s exactly what the Breakthrough Listen Initiative—a project headed by Siemion that searches for signs of intelligent life beyond Earth—will do. The team plans to observe several stars from Borra’s sample with the 2.4-meter Automated Planet Finder telescope at the Lick Observatory in California.

Borra is excited to see that others are taking the reins. “At this stage, the signal is so strange, that although our detailed analysis seems to indicate that it is a real signal, it has to be validated with more work,” he says.

Still, the Breakthrough Listen team doesn’t share Borra’s enthusiasm. According to a statement, they have rated the detection as a zero to 1 on the Rio Scale for SETI observations, meaning that it is insignificant.

In fact, Siemion thinks the spectral patterns were likely caused by errors in calibration or data analysis. And Plavchan agrees. He points to several steps in the team’s data analysis that “scared him” because they didn’t consider how those steps might affect their results—a red flag in any scientific claim. At the end of the day, the signal probably comes down to a human error, he says.

“It’s not a bad idea to look for a signal, it’s just that they didn’t do their homework,” says Plavchan.

Are aliens trying to contact Earth? Six new mysterious blasts of radio energy are detected from deep space
  • Six bursts of radio waves have been detected 3 billion light years away
  • The detection follows 11 previously recorded outbursts from the same location
  • The origin of the radio energy remains unknown, but researchers believe it may be from a young neutron star

It may be three billion light-years away from Earth, but this distant constellation could be trying to contact us.

Six bursts of radio waves have been detected from the constellation Auriga, each lasting just a few milliseconds.

While the source of the waves remains unknown, some suggest they mysterious bursts of energy could be a sign of alien life trying to contact us.

WHAT ARE FAST RADIO BURSTS?
Fast radio bursts, or FRBs, are radio emissions that appear temporarily and randomly, making them not only hard to find, but also hard to study.

The mystery stems from the fact it is not known what could produce such a short and sharp burst.

This has led some to speculate they could be anything from stars colliding to artificially created messages.

The first FRB was spotted, or rather 'heard' by radio telescopes, back in 2007.

But it was so temporary and seemingly random that it took years for astronomers to agree it wasn't a glitch in one of the telescope's instruments.

The waves were detected by researchers from McGill University in Montreal, using the Green Bank Telescope in West Virginia, and at the Arecibo Observatory in Puerto Rico.

In their paper, published in The Astrophysical Journal, the researchers, led by Paul Scholz, wrote: 'We have detected six additional radio bursts from this source: five with the Green Bank Telescope at 2 GHz, and one at 1.4 GHz with the Arecibo Observatory, for a total of 17 bursts from this source.'

The detection follows 11 previously recorded outbursts from the same location, called FRB 121102.

This is the only known repeater of fast radio bursts (FRBs) - radio emissions that appear temporarily and randomly.

Despite there being a number of FRBs from the site, the origin of the bursts is an ongoing puzzle to researchers.

Stupid about AGW!!
Chilean Navy releases what has been called a Groundbreaking UFO video. The video was shot by a Chilean Navy military Helicopter in 2014 and was just declassified and released Jan 5th

The footage was shot in 2014 on a routine training mission for one of their helicopters and the object seen was only saw when the pilots looked through their FLIR equipment. It was naked to the invisible eye but as in the video you can see the object through IR and see that it is emitting something into the atmosphere that was also only visible in the IR spectrum

The Chilean military has classified the object as a UFO

I'm skeptical. How would an invisible eye actually work? If it is invisible, light will pass directly through it, and therefore not collect on a retina.
 
It's a total WTF when you realize it was only visible with an IR camera and invisible to radar. Lots of stories about that one. Meaning it was invisible to the naked eye and radar.
It's completely insane. The first reporting of this didn't show those videos. It showed some balloon object floating and I, as well as others brushed it off as another hoax. This looks like a zamboni in the sky.

Been thinking about it some more. Possibly a satellite? They would be so far up that you wouldn't see them without using infrared during the daytime. Perhaps the heat related trail it leaves behind is just the friction glide of it's orbit, or exhaust from firing it's thrusters ( as the exhaust would spread evenly in space )?

Petrified wheel tracks found in various locations, including parts of Turkey and Spain, were left by heavy all-terrain vehicles some 12 million to 14 million years ago, according to Dr. Alexander Koltypin, a geologist and director of the Natural Science Research Center at Moscow’s International Independent University of Ecology and Politology.

This is a controversial claim, since human civilization is only thought by mainstream archaeologists to extend back several thousand years, not millions of years. That’s not to mention the idea of a prehistoric civilization advanced enough to have such vehicles.

The wheel tracks cross over faults formed in the middle and late Miocene period (about 12 to 14 million years ago), suggesting they are older than those faults, Koltypin said on his website.

At the time, the ground would have been wet and soft, like a malleable clay. The large vehicles sank into the mud as they drove over it. Tire ruts at various depths suggest that over time the area dried out. Vehicles were still driving over it as it dried, Koltypin said, and did not sink as deeply.

The vehicles were similar in length to modern cars, but the tires were about 9 inches (23 centimeters) wide....(more)

Could Mysterious Cosmic Light Flashes Be Powering Alien Spacecraft?
By Mike Wall, Space.com Senior Writer | March 9, 2017 04:32pm ET




Bizarre flashes of cosmic light may actually be generated by advanced alien civilizations, as a way to accelerate interstellar spacecraft to tremendous speeds, a new study suggests.

Astronomers have catalogued just 20 or so of these brief, superbright flashes, which are known as fast radio bursts (FRBs), since the first one was detected in 2007. FRBs seem to be coming from galaxies billions of light-years away, but what's causing them remains a mystery.


"Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence," study co-author Avi Loeb, a theorist at the Harvard-Smithsonian Center for Astrophysics, said in a statement Thursday (March 9). "An artificial origin is worth contemplating and checking." [5 Bold Claims of Alien Life]

One potential artificial origin, according to the new study, might be a gigantic radio transmitter built by intelligent aliens. So Loeb and lead author Manasvi Lingam, of Harvard University, investigated the feasibility of this possible explanation.

The duo calculated that a solar-powered transmitter could indeed beam FRB-like signals across the cosmos — but it would require a sunlight-collecting area twice the size of Earth to generate the necessary power.

And the huge amounts of energy involved wouldn't necessarily melt the structure, as long as it was water-cooled. So, Lingam and Loeb determined, such a gigantic transmitter is technologically feasible (though beyond humanity's current capabilities).

Why would aliens build such a structure? The most plausible explanation, according to the study team, is to blast interstellar spacecraft to incredible speeds. These craft would be equipped with light sails, which harness the momentum imparted by photons, much as regular ships' sails harness the wind. (Humanity has demonstrated light sails in space, and the technology is the backbone of Breakthrough Starshot, a project that aims to send tiny robotic probes to nearby star systems.)

Indeed, a transmitter capable of generating FRB-like signals could drive an interstellar spacecraft weighing 1 million tons or so, Lingam and Loeb calculated.

"That's big enough to carry living passengers across interstellar or even intergalactic distances," Lingam said in the same statement.

Humanity would catch only fleeting glimpses of the "leakage" from these powerful beams (which would be trained on the spacecraft's sail at all times), because the light source would be moving constantly with respect to Earth, the researchers pointed out.





The duo took things a bit further. Assuming that ET is responsible for most FRBs, and taking into account the estimated number of potentially habitable planets in the Milky Way (about 10 billion), Lingam and Loeb calculated an upper limit for the number of advanced alien civilizations in a galaxy like our own: 10,000.

Lingam and Loeb acknowledge the speculative nature of the study. They aren't claiming that FRBs are indeed caused byaliens; rather, they're saying that this hypothesis is worthy of consideration.

"Science isn't a matter of belief; it's a matter of evidence," Loeb said. "Deciding what’s likely ahead of time limits the possibilities. It's worth putting ideas out there and letting the data be the judge."

The new study has been accepted for publication in The Astrophysical Journal Letters. You can read it for free on the online
