The Sun unleashed a monster storm. Earth may have made it worse
The massive solar storm that illuminated skies worldwide in May 2024 has uncovered an unexpected twist: Earth's own atmosphere may have helped make the storm so powerful. Satellite measurements revealed that roughly 85% of the charged particles fueling the disturbance originated from Earth's upper atmosphere rather than the solar wind. Scientists also detected an extraordinary 40% weakening of Earth's magnetic field high above the planet.
A Monster Solar Storm Turned a Protected Region Around Earth Into a Particle Accelerator
A solar superstorm appears to have turned a normally sheltered region near Earth into a natural particle accelerator, boosting electrons to energies capable of penetrating some satellite shielding. Protecting spacecraft from radiation means understanding where hazardous particles can appear, especially during severe solar storms. Near Earth, an invisible boundary was thought to keep exceptionally energetic [...]
A study has revealed that 85% of the energy source for the super-powerful solar storm that painted the world's skies with auroras in May 2024 originated from the Earth's atmosphere, not the Sun. The study was published in the international journal Science Advances. The analysis was conducted by a research team led by Assistant Professor Naritoshi Kitamura of the Institute for Space and Earth Environment (ISEE) at Nagoya University. This storm,…
One of the most mysterious protective barriers around the Earth has turned out to be far more vulnerable than scientists thought. A powerful solar storm has caused dangerous electrons to penetrate and accelerate into an area that was considered practically impenetrable for more than a decade. A Japanese satellite has recorded an increase in the flow of high-energy particles by more than 5,000 times. The discovery, made after an analysis of the e…
