The moment the sun dips below the horizon, casting long shadows and painting the sky in hues of orange and purple, is a familiar sight. But beyond the beauty, this period of twilight holds scientific intrigue for stellar astronomers. It's in these "crepuscular" hours that celestial objects often reveal themselves, offering unique opportunities for observation and understanding.
What is Crepuscular Light?
Crepuscular, derived from the Latin word "crepusculum" meaning twilight, describes the soft, diffused light that illuminates the sky during the transition from day to night or vice versa. This light is a consequence of sunlight scattering through the Earth's atmosphere. The angle of the sunlight is low, allowing for greater scattering, which results in the characteristic warm glow of twilight.
