Today's Astronomy Picture of the Day features a vibrant aurora over the Skógafoss waterfall in Iceland, captured in a single 5-second exposure by photographer Victor Lima in April 2025. Aurora borealis, or the northern lights, captivate many with their breathtaking colors. Achieving a sighting requires high solar activity, dark and clear skies, and a location at high latitudes, making the aurora more easily seen in the Northern Hemisphere due to less landmass near the Antarctic Circle.
Charged particles from the solar wind, captured by Earth's magnetosphere and guided by the magnetic field, collide with atmospheric gas particles at the poles, resulting in different colors depending on the gas involved. Oxygen produces red and green hues, while nitrogen creates blue and pink colors. As NASA's main APOD site transitions to science.nasa.gov/apod, the featured image tomorrow remains unknown.
