10 The Ceres Mystery Lights As NASA’s Dawn spacecraft approached the
dwarf planet Ceres, it captured some very mysterious images.
One of these, taken 47,000 kilometers away from the planet, showed abnormally bright
spots inside an 80-kilometer-wide crater.
Many immediately took these images and ran with them, thinking that they were signs of
an alien civilization.
For a few months, even NASA wasn’t exactly sure what these mysterious bright spots were.
Theories ranged from aliens to ice, but in late 2015, a study was published in Nature
that debunked all those theories.
It claimed that the spots were nothing more than salt.
The study stated, “These unusual areas are consistent with hydrated magnesium sulfates
mixed with dark background material, although other compositions are possible.”
Unfortunately, this explanation is not as exciting as aliens, but there are plenty of
other space mysteries to keep us baffled for a long time.
9 The Windsor Hum
Mysterious hums like the one in Windsor, Ontario, can be found all over the world.
These hums often sound like idling engines or loud refrigerators and are understandably
a nuisance for anyone within earshot.
A recent study in Canada, however, claims to have finally found the source of Windsor’s
mysterious hum.
While their first report was totally inconclusive, the second report claims to have finally found
some answers.
It states that the origin of the hum comes from nearby Zug Island in Detroit, Michigan,
the home of a steel plant.
It’s a step in the right direction, but we still don’t know exactly where the hum
is coming from.
The intermittent noise could be coming from one specific machine, or it could be a combination
of different machines that only produce the noise under specific conditions.
Regardless, the Canadian government has requested that someone on the US side of the Detroit
River keep looking into the problem.
8 The Jewish Relic
In 2015, a maintenance worker found a bizarre object in a Jerusalem cemetery.
The object was shaped much like a rolling pin and made out of metal, and it had Israel’s
Antiquities Authority at a loss.
First believing he had found a bomb, the maintenance worker called in a bomb squad.
They did a controlled explosion, only to find that the object was completely unharmed.
The object was X-rayed and found to be made of solid metal with a coating of 24-karat
gold.
Now that the authorities knew what it was made of, they turned to the best possible
source to figure out what it actually was: the Internet.
After posting a picture on Facebook, they received thousands of guesses about the object’s
possible use.
Finally, a man named Micah Barak solved the mystery.
He posted that the object was an Isis Beamer, a device named after the Egyptian god Isis
that’s commonly used for energy healing by naturopaths.
Just as suddenly as the mystery began, it was solved with the help of Facebook.
7 Shark Navigation The ocean is a vast and empty place, yet sharks
are able to navigate the oceans with incredible accuracy.
For example, great white sharks frequently swim between Hawaii and California, while
salmon sharks swim from Alaska to the subtropical Pacific.
It’s a phenomenon that has baffled scientists for years.
Hypotheses about how sharks manage to do this range from odor cues to the Earth’s electromagnetic
fields, but until recently, nobody’s ever conclusively proven one theory over any of
the others.
A recent study claims to have finally solved the mystery.
Scientists tested the theory that the sharks manage the feat using odor by taking wild
leopard sharks 10 kilometers away from their natural habitat.
The sharks were fitted with tracking devices, and half of them had cotton balls stuffed
up their noses.
When the sharks were released, the half without the cotton balls were able to easily find
their way back, while the ones with the cotton balls appeared to become lost.
This seemed to have solved the mystery, but many remain unconvinced.
Some believe that the sharks were simply upset by having wads of cotton jammed into their
noses.
Others pointed out that the handicapped sharks still basically swam in the right direction,
so there must be something else guiding them.
6 Amelia Earhart’s Plane Amelia Earhart is one of the most famous female
aviators in history.
On July 2, 1937, she disappeared during her attempt to fly around the equator.
Since then, her mysterious disappearance has fascinated the world and inspired a host of
conspiracy theories.
In 2014, however, the International Group for Historic Aircraft Recovery, stumbled on
a piece of debris from an aluminum aircraft on the uninhabited island of Nikumaroro.
It’s now believed that the aluminum almost certainly belonged to Earhart’s twin-engine
Lockheed Electra.
The metal sheet was installed on the plane in Miami to replace a navigational window.
The Miami Herald even published a photo of the plane with the metal sheet attached.
All of the specifications and dimensions of the metal exactly match the photograph.
This is a major breakthrough because it is the first piece of evidence found since Amelia
Earhart vanished.
It also goes against the popular belief that Earhart and her navigator crashed in the Pacific
Ocean.
Instead, it is believed that they ran out of fuel and were forced to land on Nikumaroro,
becoming castaways for the rest of their lives.
5 Solving The Chaocipher
The Chaocipher was once famous for its complexity.
Now, it’s famous for its simplicity.
This cipher machine was extremely small, but it generated ciphers that went unsolved for
almost 50 years.
John Byrne was a writer who began creating the cipher in the 1920s and soon had a code
that he claimed was unsolvable.
In his many attempts to show the government and the Navy, he was ignored due to his seeming
lack of skills as a cryptanalyst.
Byrne never gave out any details about the Chaocipher until he published his autobiography,
Silent Years, which contained examples of famous documents in both plaintext and ciphertext.
But even though the Chaocipher was finally available, no one knew how to figure it out.
After Byrne’s death, the American Cryptogram Association contacted Byrne’s son to see
if he would reveal his father’s secrets.
To their dismay, he refused.
The code remained a mystery until Patricia Byrne, John Byrne’s son’s widow, finally
revealed the secret in 2010.
The mechanism contained two circles with all the letters of the alphabet on their outer
edges.
The right circle had the alphabet going clockwise in plaintext, while the left circle had it
going counterclockwise in ciphertext.
By replacing certain letters in a sequence, the machine could create a code that was indecipherable
without the machine to translate it back.
The system wholly violates Kerckhoffs’s principle, which states that a cryptogram
should be secure even if the secret of how it works is public knowledge.
Cracking the code was so difficult simply because no one knew exactly how Byrne built
his machine.
4 The Bloop
In the summer of 1997, the National Oceanic and Atmospheric Administration (NOAA) recorded
several extremely odd low-frequency sounds underwater.
“The Bloop,” as it was named, completely baffled scientists.
Dr. Christopher Fox of the NOAA did not believe the sound to be man-made or geologic in nature.
It also couldn’t have come from an animal, since it was several times louder than the
loudest known animal noise.
In 2012, the NOAA finally solved the mystery, and it is much less exciting than the gigantic
sea monster everyone thought it was.
The NOAA states that the sounds are consistent with large icebergs fracturing and cracking,
an event also known as an icequake.
Even though the Bloop was heard at two different underwater listening stations over 5,000 kilometers
apart, the explanation works.
A cracking ice shelf is definitely loud enough to generate such a noise.
3 The Fairy Circles Of The Namib Desert The appearance of the so-called “fairy circles”
in the Namib Desert has perplexed scientists for years.
According to Norbert Juergens, the explanation is simple: termites.
In his paper published in the journal Science, Juergens states that the circles are formed
when a local sand termite, Psammotermes allocerus, removes the vegetation that begins growing
after a rainstorm.
By doing this, they allow more plants to grow.
“Because of rapid percolation and lack of evapotranspiration, water is retained within
the circles.
This process results in the formation of rings of perennial vegetation that facilitate termite
survival and locally increase biodiversity.”
Even though these termites are the only insect species found distributed across the entire
area of the circles, many remain skeptical.
Ecologist Stephan Getzin criticized the theory, saying, “ there is not a single study showing
that social insects can cause such large-scale homogenous distribution patterns.”
Of course, Getzin has his own competing theory for what’s causing the fairy circles.
His theory essentially says the plants organize themselves into these formations based on
the availability of soil resources.
As of right now, Juergens seems to have the best explanation for the mysterious phenomenon.
2 Darwin’s ‘Strangest Animals As Charles Darwin ventured around the world
developing his ideas for evolution, he stumbled across the fossils of several bizarre creatures
that seemed to defy explanation.
What he’d found were fossils from Macrauchenia and Toxodon.
The Macrauchenia resembled a short, humpless camel with a small, elephant-like trunk, while
the Toxodon seemed to have the body of a rhinoceros, the head of a hippo, and the teeth of a rodent.
After analyzing the fossils, Darwin described the Toxodon as “perhaps one of the strangest
animals ever discovered.”
In the years since, the mammalian classification of these animals has completely stumped scientists.
Until now, that is.
Much of the mystery stemmed from incomplete fossil records and the fact that they were
unable to isolate fossil DNA because of degradation from South America’s warm, humid climate.
Instead of DNA, scientists decided to look at the sequence of the fossils’ collagen,
a protein that lasts much longer than DNA and makes up bones.
To do this, they took collagen samples from various mammals—both living and extinct—to
create a collagen tree.
They then compared those sequences to the collagen of the Toxodon and Macrauchenia.
Surprisingly, the scientists found that the bizarre animals were part of a group known
as the South American ungulates, which lived for about 60 million years and disappeared
12,000 years ago.
Previously, these bizarre animals were thought to be part of Afrotheria, along with elephants
and manatees, but it has now been proven that they are part of the order Perissodactyla,
which includes horses and rhinos.
This is a huge discovery in the field of phylogenetics and will hopefully help scientists uncover
the history of mammals even further into the past.
1 The Wow!
Signal In 1977, an Ohio radio telescope detected
an unexpected blast of radio waves that was over 30 times as strong as normal background
radio waves.
The anomaly lasted for 72 seconds and was so shocking that it caused astronomer Jerry
Ehman to write “Wow!” on the printout next to the circled signal, which gave the
phenomenon its name.
Many believed that it was proof of alien life.
This year, scientists think they have finally cracked the mysterious Wow! signal.
Antonio Paris, a professor at Florida’s St. Petersburg College, believes that the
signal was produced by a cloud of hydrogen gas left behind by two comets that flew past
Earth.
Paris states that from July 27 to August 15 in 1977, “comets 266P/Christensen and P/2008
Y2 were transiting in the neighborhood of the Chi Sagittarii star group.
Ephemerides for both comets during this orbital period placed them in the vicinity of the
Wow! signal.”
Since these comets were only discovered in 2006, scientists did not take them into account
when initially researching the signal.
