The term "zenith" refers to the highest point or peak of something. In astronomy, it describes the point in the sky directly above an observer. When an object, like the sun, reaches its zenith, it is at its highest position in the sky for that day, often resulting in the most intense sunlight. In a broader context, "zenith" can also signify the pinnacle of success or achievement in various fields, such as career or personal development. For example, an athlete may reach the zenith of their career by winning a championship, marking the culmination of their hard work and dedication.
