Astral, or celestial, refers to anything related to the stars, planets, and other heavenly bodies in the universe. This term often encompasses the study of astronomy, which explores the physical properties, movements, and interactions of celestial objects. Astral phenomena can include events like meteor showers, eclipses, and the appearance of comets. In various cultures, the concept of the astral realm also extends to spiritual beliefs, where it is thought to represent a plane of existence beyond the physical world. Some traditions, such as astrology, suggest that celestial bodies influence human behavior and events on Earth.
