Crepuscular rays usually appear orange because the path through the atmosphere at dawn and dusk passes through up to 40 times as much air as rays from a high Sun at noon. Particles in the air scatter short- wavelength light (blue and green) through Rayleigh scattering much more strongly than longer-wavelength yellow and red light.

Sunbursts can appear in photographs when taking a picture of the Sun through the diaphragm of a lens set to a narrow aperture due to diffraction; the effect is often called a sunstar. [ 2 ] In information visualization , a sunburst diagram or sunburst chart is a multilevel pie chart used to represent the proportion of different values found at ...
A sunbeam, in meteorological optics, is a beam of sunlight that appears to radiate from the position of the Sun. Shining through openings in clouds or between other objects such as mountains and buildings, these beams of particle-scattered sunlight are essentially parallel shafts separated by darker shadowed volumes.
A coronal mass ejection is a burst of plasma and magnetic field that erupts from the sun's corona -- essentially a huge cloud of charged particles ejected into space at high speeds.
