Record Auroras Are Reminders of Earth’s Protective Magnetic Shield

Without our magnetic field,
the particles that make auroras
would kill us and all earth life

In the past few days, millions of people in southern latitudes have been awed by red glows in the sky. The Aurora Borealis does not normally reach as far south as Los Angeles, Arizona and Georgia. Alert astrophotographers watching the news about solar flares went out to dark skies to take advantage of this treat that is usually reserved for Alaskans, Canadians and Scandinavians; that’s why it’s called the Northern Lights. (The south pole has its Southern Lights: the Aurora Australis.)

Auroras are common to planets with magnetic fields, like Jupiter and Saturn. Among the rocky planets in the inner solar system, only Earth has a large enough magnetic field to offer protection from the solar wind and all but the strongest cosmic rays. Those enjoying the spectacle of glowing curtains of light should give thanks to the Creator who ensured that the only planet with life was protected.

Bad Stuff Happens

Space is a shooting gallery. Unprotected humans would be vulnerable to solar flares and high-energy particles; that’s one of the major problems engineers must solve for lengthy moon missions or journeys to Mars.

This week, Nature reported a record-setting coronal mass ejection (CME) around another star (podcast here). The European Space Agency says it is the first confirmed CME around a star beyond the sun. The huge ‘monster eruption’ was big enough to strip away the atmosphere of any habitable planet in its orbit, says Live Science. Elizabeth Howell wrote, “Scientists detect monster blast from nearby star powerful enough to rip the atmosphere off a planet.”

Such an event would not allow space aliens much time to admire an aurora produced by it!

But We’re Protected

Earth’s magnetic field compresses under the force of powerful CME’s from our sun, sometimes enough to push it near the surface, but two factors protect us: the strength of the field, and the type of star we have: one of the most stable stars known (and among that class, the sun is among the most stable). Yes, flares do occur in our sun, but nothing like the huge, deadly flares and CMEs emitted by other star classes. Our magnetic field deflects charged particles to the frigid poles where few live. It’s the interactions of these charged particles with the atmosphere that produce the glowing auroras. Illustra Media’s beautiful, informative film ‘Heavenly Fire’ about the aurora is worth watching again:

News About the Magnetic Field

Scientists find a surprising twist in Earth’s magnetic field (Space.com, 13 Nov 2025). Scientists keep finding out new things about Earth’s very special protective shield. Sharmila Kuthunur reported about one today:

For decades, scientists believed that the magnetosphere has a simple electrical layout, with the positive charge on the morning (“dawn”) side of Earth and negative charge on the evening (“dusk”) side, reflecting how electric fields normally push charged particles from positive to negative regions. But new satellite data and computer simulations show that the picture is more complex — and partly upside down….

A team led by Yusuke Ebihara, who is a professor in the Research Institute for Sustainable Humanosphere at Kyoto University in Japan, found that the morning side of the magnetosphere actually carries a negative charge, while the evening side is positive.

The discovery could aid engineers in designing satellites for protection from space weather as well as help geophysicists understand the nature and operation of our magnetic field.

A Weak Spot in Earth’s Magnetic Field Is Going from Bad to Worse (Eos.org, 10 Nov 2025). The ‘weak spot’ is in the South Atlantic. Tom Metcalfe warns, “This could be bad news for satellites and spacefarers.”

The geomagnetic field protects life on Earth’s surface from harmful charged particles in solar radiation. We can see the effects of charged particles from the Sun interacting with the geomagnetic field in the upper atmosphere during aurorae such as the northern lights.

And because it extends into space, the geomagnetic field also protects orbiting spacecraft, including most satellites and the International Space Station (ISS). However, the study authors warn that spacecraft—and spacefarers—that enter the South Atlantic weak spot during their orbits of our planet could now be exposed to more radiation.

If you are not orbiting earth near that weak spot, no worries.

A fully liquid Earth’s core also generates a magnetic field (ETH Zurich, 30 July 2025). This article claims a refinement of dynamo theory, positing that when Earth’s core was presumably liquid a billion Darwin Years ago, it could have generated a magnetic field. Speculation aside, what is notable in the article is its confirmation of the protection our magnetic field offers:

The Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system – such as Mars – are constantly bombarded by charged particles that make life difficult.

And Now, for Space Nonsense

The evolutionists in the previous article pretend that a magnetic field a billion years ago gave life a chance to emerge:

This also places the emergence of life in a different light. Billions of years ago, life apparently benefited from the magnetic shield, which blocked harmful radiation from space, making its development possible in the first place.

Powerful solar storms may help life get going on alien planets. Here’s how (Space.com, 30 Oct 2025). Oh come now, Keith Cooper. Why are you giving nonsense good press?

A coronal mass ejection on another star has been witnessed in its entirety for the first time, revealing that when these violent outbursts take place on young stars, they pack enough energy to potentially kickstart the chemistry of life on any orbiting planets.

Yes, and impacts build finely-tuned atmospheres, comet explosions bring oceans, and big bangs produce finely-tuned universes. Lady Luck is the atheist’s goddess.

Evolutionists find order in chaos, fire and destruction. Creationists find it in Mind: the omniscient, omnipotent mind of a good Creator who loves to make beauty and display his glory to creatures He made in His image.

Regarding those billions of years, the Second Law of Thermodynamics doesn’t allow them. The earth’s magnetic field is decaying surprisingly rapidly, as Dr Henry Richter discussed in his book Spacecraft Earth (obtain here). It could not have lasted more than a few thousand years in the past (implying a recent creation) and it won’t last much longer (implying that the Final Judgment is not thousands of years in the future). Earth is on a timetable from God. Now is the day of salvation (II Corinthians 6:2).
