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.
You can define twilight simply as the time of day between daylight and darkness, whether thatâs after sunset, or before sunrise. Itâs a time when the light from the sky appears diffused and often pinkish. The sun is below the horizon, but its rays are scattered by Earthâs atmosphere to create the colors of twilight.
