A photograph taken at Hverir, a geothermally active area in northeastern Iceland, captures Earth's aurora borealis dancing above steam vents during a geomagnetic storm. Solar activity triggered the storm, sending energetic particles into Earth's magnetic field. These particles penetrated the upper atmosphere at high latitudes and created the greenish auroral display visible in the night sky. Towers of steam and gas from local fumaroles vented against the northern lights. The Sun remains in early phases of decline from the peak of its solar activity cycle, keeping auroral activity on Earth at elevated levels.
