NASA Captures Stunning 'Fire Rainbow' Over West Virginia
NASA's Astronomy Picture of the Day (APOD) for August 2, 2026, features a rare and stunning phenomenon known as a 'fire rainbow' observed over West Virginia. This optical phenomenon, also called a circumhorizontal arc, occurs when sunlight passes through ice crystals in cirrus clouds at high altitudes, creating a spectrum of colors that resemble a rainbow. The image, captured by a professional astronomer, showcases the beauty of this natural occurrence, which is dependent on specific atmospheric conditions, including the angle of the sun and the presence of hexagonal ice crystals in the sky.
