Enigmatic Blue Aurora Suggests Unexplored Atmospheric Phenomena

Space & Environment /

Picture an aurora, and you likely imagine green swirls dancing across a frozen sky. While green is common, auroras can display a variety of colors depending on altitude, location, and the atmospheric gases involved. During a powerful geomagnetic storm in May 2024, an unusual blue aurora appeared at low latitudes, reaching extraordinary heights. Using images […]
