Giant mysterious magnetic waves emanate from the Earth’s core every seven years

Published

It’s not very quiet inside the Earth. Deep below the surface, the planet is literally thundering with activity, from plate tectonics to convection currents that circulate through hot magma fluids.

Now scientists studying Earth satellite data have identified something inside the Earth that we have never seen before: a new type of magnetic wave that sweeps around the surface of our planet’s core every seven years.

This discovery can give an idea of ​​how the Earth’s magnetic field is generated, and will allow us to understand the evolution of our planet, that is, the gradual cooling of the planetary interior. The team’s research has been published in PNAS.

“Geophysicists have long theorized about the existence of such waves, but it was believed that they occur on much longer time scales than our studies have shown,” says Nicolas Gillet, a geophysicist from the University of Grenoble-Alpes (France).

“Measurements of the magnetic field from instruments based on the surface of the Earth indicated that there was some kind of wave action, but we needed the global coverage offered by measurements from space to show what was actually happening.”

The Earth’s magnetic field has long been a subject of interest to scientists. Research to date shows that an invisible structure forms a protective “bubble” around our planet, trapping harmful radiation and atmosphere. But the magnetic field is not static. It fluctuates in strength, size, and shape, has features we don’t understand, and gradually weakens over time.

The European Space Agency’s Swarm orbiting satellites are three identical probes launched in 2013 that orbit the Earth to study activity inside the Earth. It was in this data that Gillet and his team found strange new waves.

They then looked at data from other ground-based and space-based observatories collected between 1999 and 2021 and found a pattern. These waves, known as magneto-Coriolis waves, are huge magnetic columns aligned along the Earth’s axis of rotation, strongest at the equator.

This fascinating finding opens a new window into a world we can never see. This mysterious wave oscillates every seven years and propagates westward at up to 1500 kilometers a year.

Their existence suggests that there may be other magneto-Coriolis waves with different oscillation periods that we cannot detect today due to lack of data.

For now, as the waves carry information about the medium they travel through, the new discovery could be used to explore the Earth’s interior in new ways – including the core, which is still hard to study.

‘October Surprise’: Russia To Launch Nukes in Space

Published

By


The ‘national security threat’ announced on Wednesday is
about Russia planning to launch nuclear weapons in space, causing some
to speculate whether it’s really an election year ploy.

The panic began when House Intelligence Committee Chair Mike Turner
(R-Ohio) asked President Biden to declassify information about a
“serious national security threat”.

Modernity.news reports: The weapon would reportedly be designed to be used to take out satellites.

Speaker Mike Johnson (R-La.) responded by telling reporters he wanted “to assure the American people, there is no need for public alarm.”

The big, scary threat is serious business and involves a space-based nuke controlled by evil dictator Putin, but it’s also “not an immediate crisis,” according to what three members of the U.S. House Intelligence Committee have told Politico.

Okay, then. Just for election season, is it?

Zero Hedge reports: “So, the question is – was this:

a) a distraction from Biden’s broken brain, or

2) a last desperate attempt to get more funding for anything-but-the-US-border, or

iii) a path to pitching Putin as the uber-bad-guy again after his interview with Tucker Carlson.”

Just by coincidence, Mike Turner recently returned from Ukraine having lobbied for billions more in weapons and aid for Zelensky’s government.

Some questioned the timing, suggesting it might all be a deep state plot to keep American voters afraid when they hit the ballot box.

Speculation will now rage as to whether this is “the event,” real or imagined, that billionaires and elitists the world over have been building underground survival bunkers in preparation for.

Earth has built-in protection from asteroids

Asteroids are not just wandering space rocks, but a potential threat
to Earth. But what if the Earth already has its own built-in defenses
against them? Recent research published on the preprint server arXiv puts forward an unusual theory: Earth’s gravitational forces may serve as its secret shield against asteroids.

Our
planet uses powerful gravitational interactions with other celestial
bodies to break apart asteroids that approach it. These tidal forces,
akin to those that explain Earth’s tides caused by the Moon, can be so
intense that objects undergo tidal disruption, causing them to be torn
apart.

Observations of fragments of Comet Shoemaker-Levy 9 after
its collision with Jupiter in 1994 provided the first confirmation of
this phenomenon. However, for decades astronomers have been looking for
evidence that Earth or other terrestrial planets could have a similar
effect on asteroids and comets.

Planetary scientist Mikael Granvik
from the Swedish University of Technology, Luleå, led the research that
came closer to solving the above phenomenon.

His
discovery is linked to the search for gravitationally disrupted
near-Earth asteroids (NEAS), and provides compelling evidence that our
planet’s gravitational forces are not just an abstract concept, but a
factor capable of breaking asteroids into small pieces.

Based on
modeling of asteroid trajectories, Grunwick and colleague Kevin Walsh of
the Southwest Research Institute found that collisions with rocky
planets can cause asteroids to lose a significant portion of their mass,
turning them into debris streams.

New data shows that small
asteroid fragments, while not posing a threat to life on the planet, may
nevertheless increase the likelihood of local collisions like those
that occurred in Tunguska and Chelyabinsk.

Granwick assures that
asteroids smaller than 1 km in diameter are not a critical threat, but
increase the likelihood of incidents. However, it is worth remembering
the additional risks that may arise due to the formation of new debris
clouds.
