New research places the sun’s magnetic field close to the surface, upending decades of theories

New research indicates the sun’s magnetic field originates close to the surface and not deep within the star,

. This upends decades of prevailing scientific thought that placed the field more than 130,000 miles below the surface of the sun. It also brings us closer to understanding the nature of the sun’s magnetic field, which has been on scientist’s minds since Galileo.

The study, and a team of international researchers, suggests that the magnetic field actually generates 20,000 miles below the surface. This was discovered after the team ran a series of complex calculations on a NASA supercomputer. It’s worth noting that these are just initial findings and more research is required to confirm the data.

The sun’s magnetic field fluctuates in a cycle that lasts 11 years. During the strongest part of this cycle, powerful winds and sunspots form at the solar equator, along with plumes of material that cause the here on Earth. Previous theories that place the magnetic field deeper within the sun have had a difficult time connecting these various solar phenomena. Scientists hope that, given further study, they’ll be able to use this theory to not only explain the creation of solar events, but more accurately predict when they will occur.

This could lead to more than just earlier predictions of the next aurora borealis event. The sun’s intense magnetic energy is also the source of solar flares and eruptions of plasma called coronal mass ejections. When these ejections travel toward Earth, all kinds of bad things happen. This famously occurred back in 1859, when a giant geomagnetic storm created the largest solar storm in recorded history.

This is , attributed to British astronomer Richard Christopher Carrington. The solar flare, which was actually a magnetic ********** on the sun’s surface, briefly outshone the sun and caused ******** lights to erupt all over the planet, similar to the aurora borealis. It also supercharged telegraph cables, shocking operators, and set telegraph paper on *****. It was pretty ******.

Now, this was 1859, before the modern use of electricity and before computers and all related technologies. If something like the Carrington Event were to occur today, . The emitted X-rays and ultraviolet light would interfere with electronics, radio and satellite signals. The event would cause a solar radiation storm, which would be deadly to astronauts not fully equipped with protective gear.

It would also lead a coronal mass ejection to bump up against Earth’s magnetic field, which

and that was no Carrington-sized event. Even worse? We are absolutely due for this to happen. It’s basically a ticking time *****.

So these findings could, in theory, be used to prepare new early warning methods for large-scale solar flares hitting Earth. Someday, we might have solar flare warnings alongside hurricane warnings and the like. The research has already demonstrated some interesting links between sunspots and the sun’s magnetic activity.
