In January, scientists announced Earth’s magnetic field was moving quickly and in an unexpected way—traveling from Canada towards Siberia faster than it should have—and no one knew exactly why.
The sudden change in the position of the magnetic north pole meant scientists at NOAA had to do an unscheduled update to the World Magnetic Map model—the system used across the globe to ensure the accuracy of positioning in systems like GPS and aircraft navigation.
The magnetic north pole is always on the move, but the shift of its position is generally quite steady. The unexpected change could be related to a strange phenomenon known as “geomagnetic jerks.” First discovered in 1978, these jerks are characterised by the magnetic field abruptly and unexpectedly accelerating at fairly random intervals.
In a study published in the journal Nature Geology, researchers have now found the cause of geomagnetic jerks, solving the 40 year mystery.
Earth’s magnetic field is produced by the planet’s metallic core. Movements within the core cause variations to the field. This could be slow convection over long time scales, or “rapid” hydromagnetic waves that can be seen over just a few years. The geomagnetic jerks are thought to result from the second type of movement.
Julien Aubert from France’s CNRS, and colleagues used supercomputers to create a model for the jerks. They recreated conditions thought to exist at Earth’s core and then let the computer carry out what would be four million hours of calculations. From this, scientists were able to reproduce the conditions that take place before a geomagnetic jerk.
Findings showed the jerks arise when hydromagnetic waves are emitted in the inner core. The waves are amplified as they rise to the surface of the core, creating disturbances that fit with what we observe during geomagnetic jerks.
“The origin of jerks has been a riddle for geophysicists since their discovery 40 years ago,” Aubert told Newsweek. “On theoretical, or more observational grounds, many mechanisms have been proposed during those years, involving other types of core motions or waves. In our opinion the strength of our proposal is that it relies on self-consistent computer simulations of the geodynamo i.e. it solves the equations for motion and magnetic field generation that derive from the first principles of physics. So geomagnetic jerks are self-consistently generated in a framework requiring a minimal number of prior assumptions.”
He said that one limitation of the paper is that their model does not necessarily fit with geomagnetic jerks recorded in earlier periods, like the one that took place in 1969, for example.
The current findings are part of a longer-term project where scientists hope to predict the evolution of th

Are we are entering new era of fakery where they are not longer using artist impression's instead they will supply us with non debatable "AI" (sophisticated contraptions conjuring stuff) created imagery? We are about to see the first image of a black hole(10/04/2019), the supermassive black hole Sagittarius A* at the center of the Milky Way galaxy or maybe the supermassive black hole in the galaxy M87. But what is that image really showing us?
This is an recommended paper on the topic by J.P. Luminet:
Image of a spherical black hole with thin accretion disk

Britain is on a "knife edge" and likely to see an increase in coronavirus cases by July, a Government adviser has warned. Sir Jeremy Farrar, the director of the Wellcome Trust and a member of the Government's Scientific Advisory Group for Emergencies (Sage), said he was concerned that there will soon be a surge of new infections caused by lockdown restrictions being eased towards the end of May.
"I would predict, I would guess, that we will start to see a few increases in cases towards the end of June or the first week of July, and the continued lifting of restrictions and people deciding to take things into their own hands and go about life as normal," he told the BBC’s Andrew Marr Show.
"We're on a knife edge – it's very precarious, the situation, particularly in England at the moment, and I would anticipate we would see an increase in new cases over the coming weeks."
