As Alter points out, the word âimplies victory and dominance.â The âtrump cardâ in bridge and other card games is a card of a suit that temporarily ranks above any other and is derived from âtriumph,â a name for an early card game.
Astronomical Twilight, Dawn, and Dusk. Astronomical twilight occurs when the Sun is between 12 degrees and 18 degrees below the horizon. Astronomical dawn is the time when the geometric center of the Sun is at 18 degrees below the horizon. Before this time, the sky is absolutely dark.
Twilight is the illumination of the Earth's lower atmosphere when the Sun itself is not directly visible because it is below the horizon. Twilight is produced by sunlight scattering in the upper atmosphere, illuminating the lower atmosphere so that the surface of the Earth is neither completely lit nor completely dark.
