Awe is an emotion comparable to wonder but less joyous. On Robert Plutchik's wheel of emotions awe is modeled as a combination of surprise and fear.
One dictionary definition is "an overwhelming feeling of reverence, admiration, fear, etc., produced by that which is grand, sublime, extremely powerful, or the like: in awe of God; in awe of great political figures." Another dictionary definition is a "mixed emotion of reverence, respect, dread, and wonder inspired by authority, genius, great beauty, sublimity, or might: We felt awe when contemplating the works of Bach. The observers were in awe of the destructive power of the new weapon."
In general, awe is directed at objects considered to be more powerful than the subject, such as the Great Pyramid of Giza, the Grand Canyon, or the vastness of the cosmos.
Awe is difficult to define, and the meaning of the word has changed over time. Related concepts are wonder, admiration, elevation, and the sublime. In Awe: The Delights and Dangers of Our Eleventh Emotion, neuropsychologist and positive psychology guru Pearsall presents a phenomenological study of awe. He defines awe as an "overwhelming and bewildering sense of connection with a startling universe that is usually far beyond the narrow band of our consciousness." Pearsall sees awe as the 11th emotion, beyond those now scientifically accepted (i.e., love, fear, sadness, embarrassment, curiosity, pride, enjoyment, despair, guilt, and anger).” Most definitions allow for awe to be a positive or a negative experience, but when asked to describe events that elicit awe, most people only cite positive experiences.
