Astronauts aboard the International Space Station (ISS) captured an extraordinary red and green aurora lighting up large parts of Europe, a rare phenomenon visible much farther from the poles than usual. The vivid lights were caused by charged particles from the Sun interacting with Earth’s magnetosphere and atmospheric gases, with green typically from oxygen atoms at lower altitudes and red from similar interactions higher up in the atmosphere. This remote sensing from orbit gave scientists and the public a dazzling view of space weather in action, offering insight into how solar activity affects Earth’s space environment. Auroras are not just beautiful to watch but are important indicators of geomagnetic conditions that can influence satellites and communications systems. ISS observations like this help refine models that predict how solar storms propagate and interact with our planet.

The specific wavelengths of light seen in auroras are tied to the types of atoms and molecules affected by incoming solar particles. Green hues usually indicate oxygen at lower altitudes, while red signals oxygen at higher levels, each telling researchers about energy levels and particle speeds. Observing these colors from space provides a broader perspective than ground-based views because satellites can see the phenomenon stretching across wide regions. These data help scientists understand how energy from the Sun transfers into Earth’s upper atmosphere and can affect satellite drag and ionospheric conditions. Studying auroras also contributes to space weather forecasting, which is critical for protecting power grids and communication systems on the ground. By comparing events over time, researchers learn more about how various solar cycles influence Earth’s magnetic environment.
