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 time of night when the sky is illuminated by the sun but the sun is below the horizon. At any given time, one side of the planet Earth is bathed in light from the Sun (the daytime) and the other side of the Earth is in the shadow caused by the Earth blocking the light of the sun.
