Scientists say the Earth's core is slowing down and it could possibly be rotating in reverse.
How is this possible?
What does it mean for our planet?

Scientists say earth's mysterious inner core is changing shape

A new study reveals that Earth's inner core is rotating slower than the rest of the planet. Scientists suggest this shift could impact Earth's magnetic field and even alter the length of our days. What does this mean for our planet’s future?

Study: Core rotating slower than the rest of the planet

Earth's core is a gigantic ball of liquid metal and is located nearly 2,890 kilometres below us. Scientists have made a fascinating discovery in the outer core where they say a ring-like structure, similar to a doughnut is present. Research published in the journal Science Advances says that this ring is parallel to the equator.

Study co-author and Australian National University geophysicist, Prof Hrvoje Tkalčić says that it is not possible to reach the planet's core using existing technology. So they relied on seismic waves and looked at the forms generated by large earthquakes as they travelled through the Earth.

They compared the data generated by seismic detectors closer to the poles with results from nearer the Equator. They noticed that the waves slowed down near the ceiling, before the mantle. &nbsp;

“By understanding the geometry of the paths of the waves and how they traverse the outer core’s volume, we reconstructed their travel times through the Earth,” Tkalčić said.

“We realised that seismic waves slow down in the zone that mathematically is called a torus. To most people this looked like a doughnut," he said.

"Overall, the waves detected closer to the poles were travelling faster than those near the Equator."

<h2>Earth's core and magnetic field</h2>

He stressed that it was important to study the outer core since it is responsible for the magnetic field which protect Earth from the constant bombardment of charged particles from the sun.

The molten iron and nickel in the core has currents moving that act like a “giant dynamo” which generated and sustains the magnetic field. Tkalčić said the presence of this dynamo has confused scientists for years because other planets do not have it.&nbsp;

Earth's core is slightly larger than Mars. “We can think of it as a planet within our own planet,” Tkalčić said.

While the exact size of this structure is not known, it likely stretches a few hundred kilometres.

“We don’t know the exact thickness of the doughnut, but we inferred that it reaches a few hundred kilometres beneath the core-mantle boundary.”&nbsp;

It consists of lighter chemical elements such as silicon, sulphur, oxygen, hydrogen or carbon.

A mysterious 'doughnut' is sitting in molten metal inside Earth's core

Astronomers have made a record-breaking, shining discovery with the help of the European Southern Observatory’s (ESO) Very Large Telescope (VLT) by spotting the brightest quasar ever found, which is now being called the most luminous cosmic object in space.

Astronomers have made a record-breaking, shining discovery with the help of the European Southern Observatory’s (ESO) Very Large Telescope (VLT) by spotting the brightest quasar ever found, which is now being called the most luminous cosmic object in space. Quasars are the shining cores of distant galaxies that get their powers from the supermassive black holes. The reason why this quasar is shining brightest is because its black hole is growing mass and has emerged as the fastest-growing black hole to have been found to date. The matter is collected from the surroundings by such black holes through a process that is so energetic that it releases vast amounts of light. Also Read: Earth's mantle is hosting strange 'black holes' with mysterious waves. Here's what they are The light released is so high in amount that some of the quasars turn out to be the brightest objects in our sky. Generally, the most luminous quasars are just indications of the fastest-growing supermassive black holes lurking in space. “We have discovered the fastest-growing black hole known to date. It has a mass of 17 billion Suns, and eats just over a Sun per day. This makes it the most luminous object in the known Universe,” said Christian Wolf, who is the lead author of the study published in Nature Astronomy and an astronomer at the Australian National University (ANU). How the supermassive black hole is making quasar shine The quasar, which is known as J0529-4351, is so distant from Earth that its light travelled over 12 billion years to reach our planet. The matter which is getting pulled into its black hole, like a disc, has been emitting too much energy, because of which the quasar is more than 500 trillion times more luminous in comparison to the Sun. “All this light comes from a hot accretion disc that measures seven light-years in diameter — this must be the largest accretion disc in the Universe," said ANU PhD student and co-author Samuel Lai. Watch: Black hole 'moons' may signal advanced alien life This quasar was hiding in plain sight till it was found. “It is a surprise that it has remained unknown until today, when we already know about a million less impressive quasars. It has literally been staring us in the face until now,” said co-author Christopher Onken, an astronomer at ANU. He said that this cosmic object appeared in images from the ESO Schmidt Southern Sky Survey, which date back to 1980, but was not recognised as a quasar till decades later.

The intensity of the recent solar storm which had filled the skies of Earth with Northern Lights in May 2024 was so huge that its effects travelled to the bottom of the ocean.

The intensity of the recent solar storm which had filled the skies of Earth with Northern Lights in May 2024 was so huge that its effects travelled to the bottom of the ocean. In the magnetic compasses, which were used by Ocean Networks Canada (ONC) for monitoring the ocean off Canada's coast, a major distortion was recorded in the magnetic field of Earth because it was buffeted by a strong influx of particles released by the Sun. Measuring these powerful solar storms will help scientists determine what are they dealing with when similar solar eruptions occur during solar storms in the future. The data will also help scientists understand how Earth is getting affected by such solar storms. Also Read: Sun releases strongest X-ray flares since 2005, scientists warn massive sunspot yet to burst "The next two years will be the peak of the 11-year solar cycle. After a decade of relative inactivity, aurora events like this past weekend are likely to become more frequent over the next couple of years, although solar variability makes precise prediction of such events impossible," said physicist Justin Albert, who is from the University of Victoria in Canada, while speaking to Science Alert. "ONC's network might provide a very helpful additional window into the effects of solar activity on the Earth's terrestrial magnetism," he added. Why has Sun been so active lately? Solar storms, which are also called geomagnetic storms, are among those activities of the Sun which have the biggest impact on Earth. Solar storms occur when an eruption takes place on the Sun's surface and ejects billions of tonnes of material which are tangled up with magnetic fields at high speed in the Solar System. When the Sun's coronal mass ejection (CME) reaches Earth's surface, the particles hit the magnetic field and then they become entangled and accelerated till they are dumped in our atmosphere. The sparkling aurora is created by the interactions with other particles. Watch: Strong solar storm hits earth; threatens to disrupt communication & power grids Recently, the Sun has been particularly active since it is escalating towards a solar maximum and will reach its peak in its 11-year activity cycle. It was first noticed by ONC data specialist Alex Slonimer in the compass data back in March. "I looked into whether it was potentially an earthquake, but that didn't make a lot of sense because the changes in the data were lasting for too long and concurrently at different locations," Slonimer said. "Then, I looked into whether it was a solar flare as the sun has been active recently," he added. (With inputs from agencies)

Intense solar storm shakes Earth’s core, travels to bottom of ocean

Scientists have discovered an ocean about 700 kilometres below the Earth's surface. It is triple the size of all the oceans on the Earth's surface combined.

Mountains with peaks&nbsp;three to four times higher than Mount Everest have been discovered deep inside the Earth, scientists said.

Using seismology centres in Antarctica, experts found these astonishingly huge “mountains” in the boundary between the core and mantle, around 1,800 miles deep (around 2,900 kilometres).

Dubbed ultra-low velocity zones (ULVZ), these gargantuan underground mountain ranges had managed to escape the scientists’ gaze all these years until earthquakes and atomic explosions generated enough seismic data to be spotted by them, reported BBC.

To make sense of how big these mountains are, Mount Everest is around 5.5 miles high (8.8 kilometres) from the surface, while the underground mountains are said to be over 24 miles (38 kilometres) in height.

“Analysing 1000’s of seismic recordings from Antarctica, our high-definition imaging method found thin anomalous zones of material at the CMB [core-mantle boundary] everywhere we probed,” Arizona State University geophysicist Edward Garnero said in a statement.

“The material’s thickness varies from a few kilometres to 10’s of kilometres. This suggests we are seeing mountains on the core, in some places up to 5 times taller than Mt. Everest.”

<h2>How did these mountains form?</h2>

One possible explanation given by the scientists is that these ancient formations were created when oceanic crusts were forced into Earth’s interior.

They argue that it might have begun with tectonic plates slipping down into the Earth's mantle&nbsp;and sinking to the core-mantle boundary.

These then slowly spread out to form an assortment of structures, leaving a trail of both mountains and blobs. This would mean both are made from ancient oceanic crust: a combination of basalt rock and sediments from the ocean floor, albeit transformed by intense heat and pressure.

<h2>What does the discovery entail?</h2>

The study seeks to argue that these underground peaks may play a critical role in how heat escapes the Earth’s core.

Mountains 3 to 4 times larger than Everest found near Earth’s core

Earth's neighbour Mars has always been among the prime candidates when it came to search for extraterrestrial life. In order for life to thrive on a particular planet's surface, it also needs to have some favourable conditions under the surface. Movement of Earth's interior creates a protective magnetic field that protects life from harmful cosmic radiations.

Now, data obtained by NASA's InSight lander has revealed that Mars has a completely liquid core. Additionally, it is rich in Sulphur and Oxygen, the data has revealed. To reach their conclusions, scientists have analysed seismic waves caused by 'Marsquakes' that passed through the lanet's core. The international research team included seismologists from University of Maryland (UMD).

The findings have been published on April 24, 2023, in the Proceedings of the National Academy of Sciences, according to a report in SciTechDaily.

"In 1906, scientists first discovered the Earth’s core by observing how seismic waves from earthquakes were affected by traveling through it,” said UMD Associate Professor of Geology Vedran Lekic, second author of the paper, as quoted in the report.

“More than a hundred years later, we’re applying our knowledge of seismic waves to Mars. With InSight, we’re finally discovering what’s at the center of Mars and what makes Mars so similar yet distinct from Earth.”

In their study, the team of researchers studied two distant seismic events on Mars. They detected waves that travelled through the planet's core.

By using the data obtained by the measurements and more, scientists were able to measure density and compressibility of the material these seismic waves passed through.

Scientists analyse marsquake to conclude that red planet has liquid core

Scientists have discovered the Earth’s oldest ice core, with some sections potentially preserving samples as old as 5 million years.

Scientists have recovered older ice samples elsewhere before, with the oldest dating back 2.7 million years. However, these were collected closer to the surface of the ice after being pushed upward by the natural flow of the glaciers.

But the new discovery could help scientists analyse the ice sediments that contain greenhouse gases from Earth's atmosphere at a time when the planet's cycles of glacial advance and retreat were just beginning. It could also potentially offer&nbsp;clues to what triggered the ice ages.

The nearly 10-metre-long sediment-filled ice core was found in Ong Valley in the Transantarctic Mountains, which separate eastern and western Antarctica.

The study was published in The Cryosphere journal on July 15.

The scientists were able to analyse the appropriate age of the ice while drilling through ice core measuring 9.5 m (31 ft) long during the Southern Hemisphere summer of 2017 and 2018, according to Nature.com.

They have recorded the age of material at different depths. According to them, the upper section is estimated to be around 3 million years old, while the lower section was dated to between 4.3 and 5.1 million years, which is almost twice as old as the previous record-holder, at 2.7 million years.

The ice sheets from Greenland and Antarctica are key to understanding modern climate science. Traditionally, scientists drill in places where ice layers accumulate year after year, undisturbed by glacial flows.

The discovery was made by the Beyond European Project for Ice Coring in Antarctica (EPICA). It was funded by the European Commission and being carried out by the Institute of Polar Sciences of the Cnr (National Research Council of Italy) and The British Antarctic Survey (BAS).

Scientists find oldest ice core dating back to 5 million years

A new study has said that the Earth’s core, which is composed of molten nickel and iron, is rusting. The study was published in the journal Advancing Earth and Space Science.

Rusting happens when iron is exposed to moist air or oxygenated water, leading to a chemical reaction that leaves a reddish residue and&nbsp;&nbsp;making strong iron weak.

Since the core is situated 1,800 miles (2,900km) below the Earth’s surface, it was assumed that the high-pressure environment and paucity of water-bearing minerals have protected the molten outer core from rust.

But recent experiments suggested that rust can form at high pressures and could plausibly be formed at locations where water-rich slabs of Earth’s crust have sunk to the core-mantle boundary.

In the experiment, the scientists created high-pressure conditions that would exist in Earth's core. Then they introduced moisture to iron in the form of a hydroxyl-bearing mineral.

At the pressure of nearly a million atmospheres, scientists found that the chemical reaction produced iron peroxide, bearing the same structure as pyrite. This indicates that rust formation could happen in the Earth's core as well.

"This rust could shed light on the deep-water cycle in the lower mantle and the enigmatic origins of ultralow-velocity zones (ULVZs)—small, thin regions atop Earth’s fluid core that slow seismic waves significantly. It could also help answer questions about the Great Oxidation Event (GOE), which marked the beginning of Earth’s oxygen-rich atmosphere some 2.5 billion to 2.3 billion years ago," a report in the Advancing Earth and Space Science journal said.

But scientists are yet to identify the cause of the oxygenation event that may have triggered rusting.

You might also reassess some films and realise they deserved a higher place on the list than they had before," said Google in a blog post.

The timing of the current update is a little unexpected as it comes before the biggest online holiday shopping season. Earlier, Google took breaks before the holiday shopping season. This was considered as Google’s gift to webmasters said former Googler Matt Cutts.

Google begins rolling out November 2021 core update at an unusual time

Nepal&#39;s new Maoist Prime Minister Prachanda named a minority leader to the key position of home minister in his first appointments on Thursday, seeking reconciliation after months of protests by southern plainsfolk over a new constitution. 
 
Prachanda,whose real name is Pushpa Kamal Dahal, still uses his wartime pseudonym, which means &quot;fierce&quot;. He has promised to keep his cabinet small, after predecessor K P Oli was criticised for appointing a 32-member coalition with six deputy prime ministers. 
 
After the oath-taking ceremony in capital Kathmandu, Prachanda administered the oath of office to five ministers, including three from his political party and two from the Nepali Congress. 
 
The sixty-one-year-old former rebel commander has vowed to tackle the grievances of the Madhesi minority that demands a greater say in central government by amending the constitution adopted last September. 
 
The Madhesis, who have close cultural and family ties with neighbouring India, have staged protests against the charter, saying it marginalised them by dividing their southern homeland into several states. 
 
Violence, blamed by many Madhesis on the use of excessive police force, claimed more than 50 lives in protests that petered out in February. 
 
Prachanda appointed Bimalendra Nidhi of the centrist Nepali Congress, the biggest coalition party, as deputy prime minister in charge of the home ministry, officials said. 
 
Among those appointed to the cabinet was Krishna Bahadur Mahara from Prachanda&#39;s Maoist party, who will also be a deputy prime minister in charge of the finance ministry.
