In terms of celestial events, the umbra is vital during solar eclipses, as it is the area where a total eclipse can be observed. The length and intensity of the umbra can vary depending on the distance between the object casting the shadow and the object upon which the shadow falls.

Etymology
The word 'umbra' originates from Latin, meaning 'shadow' or 'shade'. It has been used in English since the late 16th century when scientific observations of eclipses became prevalent. The term was incorporated into astronomy to describe the darkest part of a shadow in celestial events. Over time, 'umbra' has also made its way into other fields, such as art and photography, where it is utilized to describe the nuances of light and shadow.
