NASA scientists BAFFLED by perfectly rectangular MILE-WIDE iceberg

NASA has made a remarkable discovery of a mile-wide rectangular iceberg with perfect right-angled corners in Antarctica. The stunning iceberg was spotted floating in the Weddell Sea last week by scientists on a NASA research plane.

The US space agency said the object’s sharp angles and flat surface suggested it had recently broken away from the Larsen C ice shelf.

It is estimated to be around 1 mile (1.6km) wide.

However its true size may never be known with only 10 percent of its total mass showing above the water.

The iceberg found is known as a ”tabular iceberg” instantly recognisable by its smooth clean-cut edges as if carved with a knife.

It’s perfect edges are formed by breaking off ice shelfs with clear precision but are rarely kept in that state for very long.

In an interview to Live Science Kelly Brunt, a glaciologist at the University of Maryland and NASA was left stunned by the “unusual” discovery.

She said: “We get two types of icebergs. We get the type that everyone can envision in their head that sank the Titanic, and they look like prisms or triangles at the surface and you know they have a crazy subsurface.“And then you have what are called ‘tabular icebergs.

“What makes this one a bit unusual is that it looks almost like a square.”

This is not the first time the Larsen C ice shelf has shed a large iceberg.

Last summer an iceberg known as A-68 detached itself and had a surface area of over 2,000 miles.

The discovery was made as part of Operation IceBridge, the largest ever aerial survey of the planet’s ice around Greenland and in Antartica.

The survey is building a three-dimensional map of the ice at both poles.

Aboriginal Australians carry DNA from an unknown species

Scientists have long held the consensus that almost all people on the planet descend from the first humans who left Africa between 40,000 and 100,000 years ago.

There is still much that geneticists and other scientists and researchers do not understand about this crucial moment in human history, and it seems that research on the subject is posing more questions than answers.

In 2016, researchers at Harvard Medical School published the findings of an exhaustive study of the human genome from all areas of the world, and discovered something amazing about the Australian aboriginal population.

They seem to have genetic markers that indicate they are descendants of an unidentified form of human being.

“Our main goal is to understand how our race came to the point where it is today, and for that, we must first study the DNA of ancient tribes,” said Mallick Swapan, who led the study and has been actively investigating the origins of the human genome. in most of his career.

He explained that the new study gathered the genetic data of 142 different human populations dispersed throughout the world that were underrepresented in large-scale studies so far.

According to Swapan, the most incredible revelation of this new study is that the Australian Aboriginal genetic code demonstrates that they carry the DNA markers that indicate the ancient crossing with an unidentified branch of humanity.

Although it was initially suspected that unusual DNA markers could indicate that Aboriginal ancestors intersected with elusive ancient species known as Denisovans, this hypothesis proved to be incorrect.

After the analysis, the scientists discovered that the DNA markers were different from the Denisovan markers, leading them to the conclusion that they had discovered the traces of a completely new form of the ancient human species.

It is known that the indigenous peoples of Australia are descendants of the first people who arrived on the continent from Africa about 50,000 years ago.

It has been assumed that the aborigines were isolated from the rest of the world for thousands of years and therefore the scientists assumed that their genetic code would be quite homogeneous. Surprisingly, this turned out not to be the case.

“The genetic signatures of an Australian aborigine from eastern Australia and western Australia are as different as those from a person from Europe and a person from Asia,” said Swapan.

The incredible diversity in the genetic code of the native peoples of Australia, in addition to the peculiar genetic marker that indicates that they intersected with an unknown human species in the past, indicates that there is still much more to discover about the ancient history of mankind ..

More than 140 new geoglyphs have been discovered in the Nazca Desert

The Nazca Desert, located in Peru, South America, continues to amaze with its findings.

Japanese scientists have discovered 142 new geoglyphs (large earth drawings) in the desert plateau. Most of these newly discovered geoglyphs are so old that even from a height it is difficult to understand what they depict. However, if their contours are carefully delineated in white-line photographs, then unusual and often anthropomorphic (humanoid ) figures appear immediately.

One of the discovered geoglyphs is particularly impressive.

It depicts a snake that has a head at each end of its body. And these heads absorb human figures.

Other exposed drawings can be seen depicting fish as well as strange geometric shapes.

Scientists at Yamagata University , Japan , led by Prof. Masato Sakai, along with specialists from IBM Power Systems, for the period 2018 – 2019, are scrutinizing the surface of Nazca and the surrounding area. Special digital equipment helps them identify barely visible land drawings.

One of the drawings depicts a strange animal, which shows a person’s feet. This animal is surprisingly dinosaur-like, with three egg-like ovals drawn over its back.

Other geoglyphs depict well-recognized animals – the lama, the eagle, the monkey and others.

For many years, drawings in the Nazca Desert have raised many questions. Why are they made? Why is it possible to see well only from a great height? What do they mean and why do some drawings depict animals and others draw incomprehensible lines or human figures?

There are also many hypotheses for these geoglyphs. Starting from being a huge ancient astronomical calendar and moving on to a message to the aliens.

A Mysterious Force is Keeping Distant Galaxies in Sync

If you’re someone who believes in synchronicity, then this research is for you. In a big way. Make that a BIG way. To illustrate what a big deal this is in the scientific community, the researchers take the rarely-seen stance of using the word “mysterious” in the title of their paper. Hey, that’s OUR word!

“For this mysterious coherence in large scales, we cautiously suggest a scenario in which it results from a possible relationship between the long-term motion of a large-scale structure and the rotations of galaxies in it.”

There’s that word again, this time in the abstract of “Mysterious Coherence in Several-megaparsec Scales between Galaxy Rotation and Neighbor Motion,” published recently in the Astrophysical Journal. The research was led by astronomer Hyeop Lee at the Korea Astronomy and Space Science Institute, South Korea’s national research institute in astronomy and space science. However, the key phrase in the abstract is “large-scale structure.”

“The observed coherence must have some relationship with large-scale structures, because it is impossible that the galaxies separated by six megaparsecs [roughly 20 million light years] directly interact with each other.”

Does it look like this?

In an interview with Vice.com, Lee explains the team’s research – a study of 445 galaxies within 400 million light years of Earth – and their “mysterious” observed synchronicity where many of the ones rotating in a direction toward Earth had neighbors that were moving toward Earth, and vice-versa. There’s no known way galaxies 20 million light years apart can exert that kind of gravitational force upon each other, so the team attempted to model a dark energy or dark matter force that could link them. The answer? Large-scale structures. Here’s a definition from the Harvard and Smithsonian Center for Astrophysics:

“Up until the latter part of the 20th Century astronomers thought, in the words of the eminent astronomer Edwin Hubble, that the universe was “sensibly uniform.” As a result of redshift surveys of large samples of galaxies we now know that the galaxies around us are distributed in an incredible tapestry of filamentary and sheet-like structures called the cosmic web. Massive clusters of galaxies lie at major “intersections” in this web. Galaxies like our own Milky Way are usually found in groups which often lie on the outskirts of clusters or superclusters. The first really large structure, the Great Wall, was discovered by CfA astronomers in the late 1980’s and is approximately 300 million light-years across.”

A cosmic web of galaxies connected by “an incredible tapestry of filamentary and sheet-like structures.” (Let’s pause here for a moment to ponder: Which came first: the planetarium or psychedelics? Asking for a friend.) Lee told Vice.com that the “mysterious coherence” the team observed was very slowly rotating in a counter-clockwise direction. Vice.com points out that this is the latest of similar studies reaching similar conclusions about large-scale structures. In a 2014 study led by Damien Hutsemékers, an astronomer at the University of Liège in Belgium, and published in the journal Astronomy & Astrophysics, the Very Large Telescope (VLT) in Chile was used to study nearly 100 quasars and the results revealed that the rotation axes of 19 quasars in this group were parallel, despite being several billion (that’s billion with a B) light years apart.

Or this?

“Galaxy spin axes are known to align with large-scale structures such as cosmic filaments but this occurs on smaller scales. However, there is currently no explanation why the axes of quasars are aligned with the axis of the large group in which they are embedded.”

The evidence points to the existence of large-scale structures keeping the galaxies of the universe connected and spinning in synchronicity. The explanation obviously needs more study before it’s accepted, but it’s worth pondering – with or without the aid of psychedelics.

One more thing to ponder … Axes of Quasars would make a great name for a Pink Floyd tribute band.
