A Brief History of Strange Signals from the Space

Since the beginning of civilization, humans have witnessed such unusual and unexplained activities that are mostly believed to be not from this world. From that prehistoric hieroglyphics charts, pictures, manuscripts to today's science-based documentary files, there is a lot of information of which exact reasons and origins are still unknown to us, and one of the most notable of them is the strange signals from outer space.


Cornell physicists Philip Morrison and Giuseppe Cocconi had speculated in a 1959-paper that any extraterrestrial civilization attempting to communicate via radio signals might do so using a frequency of 1420 megahertz (21 centimetres), which is assuredly emitted by the most common element in the Universe, Hydrogen; and it should be familiar to all technologically advanced and intelligent beings.


A few years later in 1968, there were several reports of unidentified strange signals from space that were picked up from the Arecibo radio telescope in Puerto Rico. There were articles from 1968 in various newspapers that mention these strange signals as the probable evidence of Extraterrestrial intellectuals' existence. And Dr. Frank Donald Drake who is famous for his eponymous equation (Drake Equation) for the probability of extraterrestrial life, shows the keen interest in that mysterious event.

Five years later in 1973, after completing an extensive survey of extragalactic radio sources, Ohio State University assigned the now-defunct Ohio State University Radio Observatory or aka "The Big Ear", then located near the Perkins Observatory in Delaware, Ohio, United States to the scientific search for extraterrestrial intelligence (SETI), in the longest-running program of its kind in history.

Next year, Dr. Frank Drake imagined a step ahead and miraculously created a message with help from Carl Sagan, that is known as "The Arecibo Message" which is an interstellar radio message, carrying basic information about humanity and Earth sent to globular star cluster M13 in the hope that extraterrestrial intelligence might receive and decipher it.

The message's separate parts highlighted with colours. The actual binary transmission carried no colour information.

"The Arecibo Message" consists of seven parts that encode the following (from the top down)

➟ The numbers one (1) to ten (10) (white)

➟ The atomic numbers of the elements, hydrogen carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA) (purple)

➟ The formula for the sugars and bases in the nucleotides of DNA (green)

➟ The number of nucleotides in DNA, and a graphic of the double helix structure of DNA (white & blue)

➟ A graphic figure of a human, the dimension (physical height) of an average man, and the human population of Earth (red, blue/white, & white respectively)

➟ A graphic of the Solar System indicating which of the planets the message is coming from (yellow)

➟ A graphic of the Arecibo radio telescope and the dimension (the physical diameter) of the transmitting antenna dish (purple, white, & blue)

The message was broadcast into space a single time via radio waves at a special ceremony to mark the remodelling of the Arecibo radio telescope in Puerto Rico on 16 November 1974.


On August 15, 1977, The Big Ear radio telescope of Ohio State University received a strong narrowband radio signal which was later used to support the search for extraterrestrial intelligence. The signal appeared to come from the constellation Sagittarius and bore the expected hallmarks of extraterrestrial origin. The radio signal lasted for only 72 seconds and it was never heard again.

Astronomer and a SETI researcher, Jerry R. Ehman, discovered the anomaly a few days later while reviewing the recorded data. He was so surprised by the result that he circled the reading (6EQUJ5) on the computer printout and wrote the comment Wow! on its side, leading to the event's widely used name. Two different values for the Wow! signal's frequency has been given: 1420.36 MHz by J. D. Kraus and 1420.46 MHz by Jerry R. Ehman, both of which are very close to the value of 1420.41 MHz of the hydrogen line, as predicted by Morrison and Cocconi.


The Wow! signal is considered to be one of the most mysterious astronomical phenomena which many people believe conveys a communication message from Extraterrestrial Intelligence. Whereas a team of researchers with the Center of Planetary Science (CPS) has straightly confirmed in their new 2017 research paper that this mystical signal was actually generated by a comet.

27 years later of sending "The Arecibo Message," in 2001, the crop circle phenomenon gained some well-deserved attention when a pattern in the form of a response to the 1974 broadcast appeared right next to Britain’s largest telescope, the Chilbolton, and observatory, home to the world’s largest fully steerable meteorological radar. It’s one of the most amazing crop circles to ever appear, regardless of whether you believe it was done by human beings or an extraterrestrial intelligence.


Above is a picture of what seems to be the response to the message sent out in 1974 by NASA (you could also see the first image of this post for clear observation). The message describes a different solar system, an image of the sender just like on the original NASA's Arecibo message, non-human DNA, and a microwave antenna instead of the radio-wave antenna that was depicted in ours.

The face you see there appeared three days before the rectangular image. The face represented a new technique in crop circle generation, a screening technique that is also used for printing a face on a piece of paper. Although the mainstream scientists believe it to be written off as a hoax, like most crop circles are within.

Not many people are aware of the fact that crop circles occur all over the world and there have been reports of them for decades. Some of their designs are so complex and elaborate that they’ve completely baffled onlookers, researchers, and scientists alike. Not only that, many of the designs are often electrostatically charged, usually with the nodes of some of the plant stalks blasted out on one side. Some of them are also littered with strange magnetic particles. This effect has been replicated by highly localized microwave heating, which causes the water inside the plants to vaporize and dislodge, thus flopping the stock completely over to one side.

This fact has led some physicists to publish work on the phenomenon, concluding that the perpetrators (who have never been caught in the act of making a crop circle, anywhere) are using GPS devices, lasers, and microwaves to create these astonishing geometric forms.


From the year of 2007, researchers have astonishingly been observing another strange signal or sound called Fast Radio Burst (FRB) that comes from outside our own galaxy repeatedly. Fast Radio Bursts are named by the date the signal was recorded, as "FRB YYMMDD". The first fast radio burst to be described, the Lorimer Burst FRB 010724, was identified in 2007 in archived data recorded by the Parkes Observatory on 24 July 2001.

There are 26 evidential reports of Fast Radio Bursts till to this date but experts are no closer to finding out exactly what it is – or where it comes from. To put it simply, the signal discovery is similar to hear a loud bang and then turning around and finding nothing. The Stargazers are left without any clues and have no idea of the direction the sound came from.

There are theories that the bursts come from massive neutron stars emitting huge rays, called pulsars, or they could be emanating from black holes or rotating neutron stars with extremely strong magnetic fields. Whereas, Harvard researchers have suggested that these FRB are caused by alien space travel or advanced alien technology. But there’s hope that it could be alien life trying to get in contact.

On May 12, 2017, researchers at Arecibo Observatory had observed mysterious signals coming from Ross 128, a red dwarf star located about 11 light-years from Earth. The star is about 2,800 times dimmer than the sun and not yet known to have any planets, and it's the 15th closest star to the Sun. According to the reports, the star was observed for ten minutes, during which time the wide-band radio signal was "almost periodic" and decreased in frequency. No such signals were detected in further follow-up studies by Arecibo, whereas some have suggested that the signals were actually made from radio frequency interference from an artificial satellite orbiting the Earth, and the debate continues.

In such cases of unusual circumstances, taking everything from the normal point of view is our birth trait. In this way, we used to try to convince others and sometimes ourselves. So, what do you think of these strange outer space signal phenomena?? Feel free to share your valuable opinions in the comment box below. [source]

Santiago Flight 513 Lands With 92 Skeletons On Board After 35 Years??!

Santiago Flight 513 Commercial Airliner takes off in Germany in 1954, lands in Brazil in 1989 with 92 skeletons on board ― with dead pilot still at the controls.


It seems like beyond science fiction, but for some years this strange story has been circulating on the internet through various web-sources. Actually, this extraordinary story was first published as a breathtaking news by the Weekly World News Tabloid, in its 14 Nov 1989 Edition. Where the newspaper reporter Irwin Fisher’s report confirms the sketchy details that surround this flight. Was it a conclusive news or it was just a sensational hoax??


According to Brazilian aviation authorities, a commercial airliner Santiago flight 513 took off from Germany on September 4th 1954 and vanished somewhere over the Atlantic ocean. A fruitless massive search was conducted and the forlorn investigators were finally forced to believe that the aircraft was crashed and all the passengers had lost their lives.
But the story becomes more fasc…

Omayra Sánchez Garzón | A Brave Colombian Girl And Her Unforgettable Story

A Colombian girl named Omayra Sánchez Garzón born on August 28, 1972, was peacefully living in the town of Armero in Tolima with his small family. And when Sánchez was only 13 years old, she couldn't think that a dark time was surrounding them beneath a silence of nature, and soon it would swallow their whole territory, making one of the world's deadliest macabre events.
On November 13, 1985, a small eruption of Nevado del Ruiz volcano located close to the Armero territory, produced an enormous lahar (mudflows of volcanic ash mixed with water) of volcanic debris mixed with ice that interred and destroyed the entire town of Armero and 13 other villages in Tolima, causing an estimated 25,000 deaths. This tragic sequel later became known as the Armero tragedy—the deadliest lahar in recorded history.

Prior to the eruption, Sánchez was at home with her father Álvaro Enrique, a rice and sorghum collector, brother Álvaro Enrique and aunt María Adela Garzón, and her mother María Alei…

Toyol and Tiyanak ― The Mischievous Child Spirits

From thousands of years ago, the Asian cultures and beliefs have presented such strange events in front of the world that are more eager to excite the curious people across all over the globe. Here we are going to talk about such a startling mythical character of "ghosts-ghouls-demons" from the South-East Asian cultures that is largely known as Toyol in the Malaysian folklore, and in Indonesia, it is called the Tuyul.

Toyol is said to be the twisted spirit of a small child who passed away before it could be born. Goblin-like structure, this spooky baby looks like a toddler, newborn or under development (fetus) baby with grey or green skin and reddened eyes. They have very sharp teeth and pointed ear. The name "Toyol" literally means "mischievous thief”. The Toyol is similar to a creature from Filipino mythology called the Tiyanak and the legendary Guman Thong from Thailand.

Tiyanak is said to be a vampiric creature that imitates the form of a child. It usually…

Hisashi Ouchi | Tokaimura Nuclear Accident | The Unbearable 83 Days Of Dying

The Second Tokaimura Nuclear Accident conveys the nuclear disaster which occurred on September 30, 1999, resulting in two horrific nuclear deaths. It is one of the world's worst civilian nuclear radiation accidents that happened in a uranium fuel reprocessing operated by the Japan Nuclear Fuel Conversion Co. (JCO) at the village of Tokai, in the District of Naka, in Japan.
Three lab workers, Hisashi Ouchi, Yutaka Yokokawa and Masato Shinohara were together preparing a measurable batch of nuclear-fuel by adding uranium solution to the precipitation tanks. Due to lack of experience, they mistakenly added an excessive quantity of uranium (about 16kg) to one of those tanks which reached to its critical condition. Eventually, a self-sustaining nuclear chain reaction started in all of sudden and the horrible accident took place.

Unfortunately, Hisashi was the nearest-one from the explosion who was injured most. He received 17 sieverts (Sv) of radiation while 50 mSv is considered as the m…

250K Years Old Extraterrestrial Aluminium Wedge Or Just A Hoax?!!

In 1974, a group of building workers while working on the shores of the Mures River near the town of Aiud in central Romania, discovered three different objects 10 meters (33 feet) deep in a sand trench, of which two were the prehistoric elephant's fossilized bones but the third object was looked like a wedge of very light man-made metal such as aluminium, which was mysteriously located alongside the two fossilized bones.


This mysterious metal wedge was 7.8 inches long, 4.9 inches wide and 2.8 inches thick, and was initially conceived to be the end of an aluminium axe.
This incredible find dumbfounded most of the researchers when the Romanian authorities dated the bone fossils as being 2.5 million years old and the aluminium piece as being 250,000 years old, as aluminium was difficult to create even by the 19th century.



The experts were more puzzled when they observed the concavities of the wedge and the further tests had revealed that it was made of 12 different metals and was a…

A 300 Million-Year-Old Brass Bell?!!

In 1944, as a ten-year-old boy, Newton Anderson’s task was to keep the coal furnace stoked at his home in Buckhannon, West Virginia, US. One evening he went into the basement to refuel the furnace and carried a particularly large lump of coal on his shovel. As he carried the loaded shovel, it wobbled and the coal fell onto the floor, breaking the lump in two. A slender metallic object was revealed, protruding from one of the broken halves. Anderson set aside the piece with the curious object and placed the remainder into the furnace.
Over the next couple of days, the boy extracted a small bell from the coal, first by whacking it with a croquet mallet and then by cleaning it with lye and a scrub brush. Unfortunately, he scoured all the coal off the intriguing artefact! But his parents and others witnessed the bell that he brought up from the basement and it became an object of conversation, residing on an old secretary desk shelf.

Coal is found in sedimentary strata (layers of soil or…

The USS Stein Monster

The USS Stein Monster was a properly unidentified sea creature that apparently attacked the Knox-class destroyer escort USS Stein (DE -1065), which was later redesignated as a Frigate (FF-1065) in the US Navy.

The ship had got its name USS Stein after Tony Stein, who was the first Marine to receive the 'Medal of Honor' for action in the Battle of Iwo Jima. USS Stein was commissioned on 8 January 1972, and after two decades of her restless service, she got decommissioned on 19 March 1992.
In 1976, the USS Stein was attacked by a sea monster believed to be an unknown species of giant squid, which damaged the "NOFOUL" rubber coating of her AN/SQS-26 SONAR dome. Over 8 per cent of the surface coating was unbelievably damaged. Nearly all of the cuts contained remains of sharp, curved claws found on the rims of suction cups of some squid's tentacles. The claws were indeed much larger than any reported at that time which indicated the monstrous creature to may have bee…

Atacama Skeleton | A 15cm Long Complete Human Body

Back in 2003, a Chilean man named Oscar Muñoz found a strange miniature skeleton called Ata, near an old church in the deserted town of La Noria, located in the Atacama Desert.


The 15cm long structure appears to be a complete human skeleton, and the primary DNA analyses indicated that it was a female human body. There are many theories about Ata’s mutation, size and shape. Most of them suggest that Ata was a human fetus born too prematurely for survival, whereas other theories suggest that the skeleton is the remains of an alien. Scientists conducted tons of studies and exams on Ata, but they still haven’t figured out the whole mystery surrounding this strange miniature skeleton.
The recent studies state that the fetus had a rare bone ageing disorder, as well as other genetic mutations in genes associated with dwarfism, scoliosis, and abnormalities in the muscles and skeleton. The researchers have identified 64 unusual mutations in 7 genes linked to the skeletal system, and they noted…

Beware Before You Mess Up With Robert The Haunted Doll

In the early 1900s, there lived a little boy named Robert Eugene Otto or shortly called as Gene in the Otto Family in Key West, Florida, United States, who got a strange, straw-filled doll from one of their family maids to play with. Only 4-year-old Gene showed the immense love to his life-sized doll and would like to bring it along everywhere, even naming it 'Robert' after himself. It was not long, however, before people began to notice the signs of Robert the Doll’s evil and mischievous nature.


As rumour has it, the Otto family members and their servants would often hear Gene in his bedroom, having conversations with himself in two entirely different voices which spooked them out so much. Furthermore, the Ottos would wake up in the midnight hours to screaming from Gene's bedroom, only to find him terrified in bed, surrounded by scattered and overturned furniture. Gene would blame Robert the Doll for all those awkward messing events, while Robert would glare at him from t…

Jean Hilliard | Who Came Back To Life After Freezing Solid For Six Hours

Jean Hilliard (born in 1961), from Lengby, Minnesota, is a survivor of a severe 6-hour freezing at -30 °C in rural northwestern Minnesota, United States.


At the cold midnight of December 20, 1980, Jean was driving home from a friend's house when she faced an accident that resulted in car failure due to sub-zero temperature, and she started walking for a nearby friend’s house that was two miles away. Eventually, her body became so futile in the frosty weather that she collapsed 15 feet outside of her friend's door, and was found “frozen solid” at 7 a.m. after being in the extreme cold for at least six hours. At that time, the temperature had already dropped down to −30 °C.



She was immediately transported to Fosston Hospital where doctors said her skin was too hard to pierce with a hypodermic needle and her body temperature was too low to register on a thermometer. Her face was ashen and her eyes were solid with no response to light. Her pulse was slowed to approximately 12 beats …
