Red Storms in the Dark: Japan's Eerie Auroras Reveal Hidden Secrets of Space Weather A team of researchers from Hokkaido University has made a groundbreaking find regarding the mysterious red auroras that dance across the horizon above Japan.
These towering red auroras, previously considered rare and understudied, have been found to reach altitudes of up to 800 kilometers above Earth's surface.
According to a study published in the Journal of Space Weather and Space Climate, these auroras are linked to a phenomenon known as magnetospheric compression, where dense streams of solar wind squeeze Earth's magnetic field and push the upper atmosphere upward.
