Solar Storm Sparks Northern Lights Across Western Hemisphere on New Year's Eve
Solar storms on New Year’s Eve sparked breathtaking auroras across the US and Europe, with vibrant displays visible as far south as California, Austria, and Germany. Two coronal mass ejections (CMEs) struck Earth’s magnetic field, causing geomagnetic storms that reached G3 levels on January 1.

Study Explores Sun’s Magnetic Field Changes and Solar Wind Acceleration
A study published in The Astrophysical Journal has shed light on how the Sun’s magnetic field influences solar wind acceleration. Using data from the Parker Solar Probe and Solar Orbiter, researchers observed that sharp magnetic switchbacks smooth out into gentler waves as they travel further from the Sun. This relaxation process transfers magnet...

Updated World Magnetic Model Predicts Magnetic North Pole’s Shift
On December 17, the National Centers for Environmental Information and the British Geological Survey released an updated version of the World Magnetic Model, designed to predict Earth's magnetic field changes over the next five years. The update is crucial for ensuring the accuracy of navigation systems, including satellite and smartphone applicati...

Geomagnetic Shield Weakening Over North America, Claim Chinese Researchers
Over the last 30 years, the magnetic field strength in the region has dropped to a level that is barely above the global average.

A Geomagnetic Storm Has Hit Earth. Here's What It Is And What Causes Them
A geomagnetic storm lit up the night sky in parts of the US during the first weekend in October. South Africas National Space Agency (Sansa) told reporters that the storm had originated from a solar flare "that erupted from sunspot 3842 on October 3

Supercooling of Earth's Inner Core May Finally Reveal its True Age, Highlights New Report
New research into Earth’s inner core suggests that supercooling, a process where a liquid cools below its freezing point without solidifying, may reveal that the core is much younger than previously thought. Composed of iron and nickel, the core plays a critical role in maintaining Earth’s magnetic field, which protects the planet from harmful ...

Aurora Season in September 2024 Could Bring Vibrant Northern Lights Due to Earth's Tilt
Auroras are expected to be more intense around September's equinox due to the Russell-McPherron Effect. The phenomenon occurs when Earth's magnetic field temporarily aligns with the solar wind, allowing charged particles to penetrate and interact with our atmosphere. This interaction causes vibrant Northern Lights, especially during the equinox. Wi...

24-Year-Old Satellite To Burn Up Over Pacific Ocean On Earth Re-Entry
After 24 years diligently studying Earth's magnetic field, a satellite will mostly burn up over the Pacific Ocean on Sunday during a "targeted" re-entry into the atmosphere, in a first for the European Space Agency as it seeks to reduce space debris.

NASA Explains How Intense Geomagnetic Storms Lead to Stunning Auroras
The National Oceanic and Atmospheric Administration (NOAA) has issued a warning about an intense geomagnetic storm at level G4, which is likely to disrupt power grids, GPS, and radio signals. Despite these potential issues, the storm offers a remarkable visual treat with colourful auroras visible in high-latitude areas of Canada and the United Stat...

Sun's Magnetic Field May Originate Closer To Solar Surface: Study
The sun's magnetic field, which causes solar storms like the one that hit Earth this month and produced beautiful auroras, may originate at shallower depths in the star's interior than previously thought, according to researchers.

Earth's Poles Are Moving And Will Flip. Why Is That A Cause Of Worry
When such reversals happen, there comes a time when the magnetic shield shrinks to zero before growing again with the opposite polarity.

What If The Earth Stops Spinning? Results Will Be Devastating, Say Experts
The Earth is spinning in space, which is pretty much empty. In space, there is not even air to push against and slow down the Earth's spin.
