One of the greatest deep-sea mysteries in the world had kept scientists engaged for more than a decade but now they claim to have most likely solved it. In 2011, Swedish explorers Peter Lindberg and Denis Asberg were on the search for treasure inside the Baltic Sea when a shocking structure was detected by their sonar radars. The structure was present 300 feet (90 metres) beneath the waves and it had a circular shape with a diameter of approximately 200 feet (60 metres), as reported by the Discovery Channel. As per the report, the form had angular lines and to many, it appeared eerily similar to the iconic Star Wars starship the Millennium Falcon. Scientists also claimed that the structure had “stair-like formations” and 660 feet (200 metres) away from it was another unknown object. While speaking to Sweden’s TV4 about the unique find, Asberg said, “We were really surprised and puzzled. We were thinking, ‘What is that we have found here?’. This is not a wreck. At that time we thought for sure there was a natural explanation." “We wanted to look into it some more and decided to keep this totally quiet. We contacted geologists, marine biologists and when they said they had never seen anything like this, of course, more thoughts were triggered. It could be something really awesome that we’ve found," he added. Also Read: There is an ancient underwater 'Stonehenge' beneath Lake Michigan in US. It was created by... The weird structure prompted speculations about it being the remains of an ancient civilisation or UFO or hidden Nazi weapon or secret World War II bunker. Lindberg, offering his own theories regarding the structure to NBC in 2012, said, "It has these very strange stair formations, and if it is constructed, it must have been constructed tens of thousands of years ago before the Ice Age." "If this is Atlantis, that would be quite amazing," he added. Not Atlantis, here's what scientists claim the structure is In 2016, the Ocean X team explored the structure, took some samples from the site and made a documentary on it. After studying the samples, Stockholm University geologist Volker Bruchert said, "What has been generously ignored by the Ocean-X team is that most of the samples they have brought up from the sea bottom are granites and gneisses and sandstones." After the analysis, he claimed that the object was not at all mysterious. Also Read: Another world with six-storey buildings beneath the Arctic? Here's what scientists found on its seafloor "I was surprised when I researched the material. I found a great black stone that could be a volcanic rock. My hypothesis is that this object, this structure was formed during the Ice Age many thousands of years ago," he added. The researchers also agreed that it was created by the process of glacial movements which had occurred during the Ice Age. Some even suggested that it was made of sandstone or basalt or from hardened lava which was produced from an underwater volcano. (With inputs from agencies)

'Stair-like formations' beneath the Baltic Sea? Scientists decode mystery behind 'alien' structure

In an unbelievable discovery, scientists have found multiple mysterious underwater structures on the seafloor of the remote area of the&nbsp;Arctic.

The international team of researchers discovered a vast range of formations that were larger than football fields.&nbsp;

These "modern" formations stood at the edge of the&nbsp;Canadian&nbsp;Beaufort Sea.

Previously, the experts have spotted many gaping craters which are filled with ice and sediment and believed that it was created due to the ancient permafrost under the waves.

According to a report published in IFL Science, between 2010 and 2022, a total of 65 newly formed craters were found by the scientists, the largest of which was said to be of the size of a city block and featuring six-storey buildings.

The team was headed by the Monterey Bay Aquarium Research Institute (MBARI). They earlier thought that the permafrost spread over the area in the last stage of the ice age nearly 11,000 years ago.

However, when sea levels rose, the ancient permafrost on the Arctic shelf was covered.

<h2>Truth behind mysterious structure in the Arctic</h2>

In the latest research, the scientists took the help of underwater robots to collect samples from inside the newly-formed seafloor craters.

When the ice was analysed, it was found that the ice formed in present-day conditions.

Scientists found that the ice was created when deeper layers of ancient permafrost started melting under the sea and created brackish (slightly salty) groundwater which rose and sank again only to get refreeze on the seafloor.

According to a report published in IFL Science, the groundwater remains frozen at a temperature of -1.4C (29.5F) till the process starts again.

“These findings upend our assumptions about underwater permafrost,” said the study’s lead author Charlie Paull, of the MBARI, in a&nbsp;statement.

“We previously believed all underwater permafrost was leftover from the last ice age, but we’ve learned that submarine permafrost ice is also actively forming and decomposing on the modern seafloor,” he added.

“Our work shows that permafrost ice is both actively forming and decomposing near the seafloor over widespread areas, creating a dynamic underwater landscape with massive sinkholes and large mounds of ice covered in sediment," Paull stated.

Another world with six-storey buildings beneath the Arctic? Here's what scientists found on its seafloor

Scientists from the University of Maryland have stumbled upon the evidence of an ancient seafloor which is believed to have sunk deep into the Earth when dinosaurs existed and is now affecting the interior structure of Earth.

This previously unknown patch of the seafloor is located in the East Pacific Rise and has thrown light on the inner workings of the planet and how the surface of Earth has gone through changes over millions of years.&nbsp;

The findings of the team were published&nbsp;in the journal&nbsp;Science Advances.

The team, headed by geology postdoctoral researcher Jingchuan Wang, used innovative seismic imaging techniques to look deep into the mantle of Earth, which is the layer between the planet's core and crust.

The scientists looked into the&nbsp;mantle transition zone, which is a region between 410 and 660 kilometres below the surface of the Earth, and discovered an unusually thick area.

The upper and lower mantles of the Earth are separated by this zone, which expands or contracts on the basis of temperature.

According to the team, this seafloor can also explain the Pacific Large Low Shear Velocity Province's (LLSVP) anomalous structure.

"This thickened area is like a fossilized fingerprint of an ancient piece of seafloor that subducted into the Earth approximately 250 million years ago. It's giving us a glimpse into Earth's past that we've never had before," Wang said.

<h2>Here's how scientists found the subducted seafloor</h2>

Subduction takes place when one tectonic plate slides below the other one and the surface material is recycled back into the mantle of Earth.

The clues of subduction&nbsp;are found by geologists after examining rock samples and sediments found on the surface of the Earth.&nbsp;

However, Wang used seismic waves to look into the ocean floor.

The scientists, by looking into the seismic waves which travelled through different layers of the planet, were able to create a detailed map of structures inside the mantle.

"You can think of seismic imaging as something similar to a CT scan. It's basically allowed us to have a cross-sectional view of our planet's insides," said Wang.&nbsp;

"Usually, oceanic slabs of material are consumed by the Earth completely, leaving no discernible traces on the surface. But seeing the ancient subduction slab through this perspective gave us new insights into the relationship between very deep Earth structures and surface geology, which were not obvious before," he added.

While observing the seafloors, the scientists found that the material was moving through the interior of Earth much more slowly than earlier believed.

Wang said that the thickness of the area hinted at the presence of colder material in the mantle transition zone and that some oceanic slabs may have been stuck while sinking through the mantle.

"We found that in this region, the material was sinking at about half the speed we expected, which suggests that the mantle transition zone can act like a barrier and slow down the movement of material through the Earth," said Wang.&nbsp;

"Our discovery opens up new questions about how the deep Earth influences what we see on the surface across vast distances and timescales," he added.

An ancient sunk seafloor beneath Pacific is impacting Earth's interior. Here's how

Manchester United are more willing and better prepared to attack opponents under caretaker manager Ole Gunnar Solskjaer than Jose Mourinho, according to midfielder Paul Pogba.

The French World Cup winner's own return to form is in keeping with a rejuvenated United as a whole since the Norwegian replaced the sacked Mourinho last month.

Pogba, who was dropped by Mourinho for his final three Premier League games in charge, has scored four goals and provided four assists as Solskjaer has become the first United manager to win all of his first six games.

"The way we are playing we have more possession of the ball. We know more where to attack and where to go. We have more of a pattern of play and more of a structure," Pogba told Sky Sports News.

"That makes it easier for everyone. So I would not say it is only myself. Yes, I have scored a few goals and had a few assists but it is all the team."

Pogba was the provider for Marcus Rashford's winner in a 1-0 victory at Tottenham last weekend that allowed United to close to within six points of the Premier League top four, having been 11 points adrift when Mourinho departed on December 18.

However, United were also indebted to goalkeeper David de Gea, who made 11 second-half saves at Wembley.

"It was great for us. It was great to show we are coming back and getting closer to the top," Pogba said. "We needed points and we showed that we could beat a big team.

"I wouldn't say (we had) luck because you create your own luck. David did his job and I thank him for that."
