This total solar eclipse looked strangely golden — here’s why
Spain’s total solar eclipse delivered an unexpected sight: a corona glowing gold instead of its usual pearly white. Because the Sun was setting, its light passed through more atmosphere, while smoke from nearby wildfires filtered out even more blue light. The result was a dramatic golden eclipse, punctuated by a bright pink solar prominence.
Last week's total solar eclipse presented a unique spectacle for observers in Spain. As the Moon completely blocked the Sun's bright disk, the typically white or silvery solar corona became unusually golden. This striking golden appearance was a result of the Sun's light traveling through a thicker portion of Earth's atmosphere during totality, scattering shorter blue wavelengths more effectively.
This phenomenon, which also causes sunsets to appear orange and red, was intensified by a large amount of smoke from nearby forest fires. The smoke particles further scattered blue light, enhancing the golden hues surrounding the eclipsed Sun. Despite the atmospheric filtering, a large solar prominence along the Sun's left edge emitted strongly in light associated with hydrogen, preserving its vivid pink color.
This vivid pink prominence added to the already rare and striking appearance of the eclipse scene, creating a visually captivating moment captured from Benavente, Spain.
