A nadir is the opposite of the zenith. A zenith is the highest point. The nadir is the lowest point. In order to understand the astronomy nadir, you need to understand that the nadir is the lowest point. It is often used when talking about waves along the electromagnetic spectrum. When used in astronomy, it means the point directly below the observer. In other words, it is the earth directly beneath your feet when you are standing up. The point directly above the observer is the astronomy zenith, and the point directly horizontal to the observer is the astronomical horizon. The true horizon is the angle of the observer relative to the curvature of the earth. These terms are all important because it allows an observer to place himself in relation to what he is observing, and he can do so using terms understood by everybody in the scientific community. In other words, there are four points of view when discussing astronomy, and the nadir is the area point directly beneath the observer.
There are many reasons why you might want to learn about this term.
