COLORADO, USA — Were you like many 9NEWS viewers who spotted those spectacular rays on both horizons during Wednesday night's sunset?
Crepuscular rays — beams stemming from the setting or rising sun — are created by clouds or mountains obstructing the sunlight, splitting the sky into beams and shadows
When they appear on the horizon opposite the sunset, or sunrise, they are called anti-crepuscular rays.
In most cases, these rays appear to be emanating from, or converging towards, a single point on the horizon — and fanning out from there. This is an optical illusion due to perspective.
The rays are actually parallel to one another. On both horizons.
