In science
- In astronomy (and also in astrodynamics), the anomaly is the angular distance of a planet from its periapsis:
- The true anomaly is observed from the primary (I.e., from the orbit's focus);
- The eccentric anomaly is observed from the centre of the ellipse, using a projection of the planet's position onto the circumscribing circle; and
- The mean anomaly is the fraction of an orbital period that has elapsed, expressed as an angle.
- In an anomaly time series the times are not uniformly spaced.
- In physics, an anomaly is a classical symmetry that is not a symmetry of the quantum theory. See anomaly (physics) and conformal anomaly, chiral anomaly, gravitational anomaly, gauge anomaly, mixed anomaly, global anomaly, parity anomaly.
- In geodesy and geophysics, the gravity anomaly (e.g., Bouguer anomaly or free-air anomaly) measures variations in the Earth's gravitational field.
- In spacecraft operations, an anomaly is an event that results in an unexpected and unwanted event that may cause a negative impact to the state of health of the spacecraft.
In pseudoscience and mysticism
- The Ararat anomaly, an object on Mount Ararat clamed to be Noah's Ark.
- The anomaly, a spiritual belief system.
In arts and entertainment
- Anomaly (dk-band) is a rock 'n' metal band from Denmark.
- Anomaly (band) is a Progressive Metal band from Malta.
- "Anomaly (Enterprise episode)", a third season episode of Star Trek: Enterprise.
- Anomaly (comics) is a DC Comics villain.
- The protagonist in the Storm (comic) is titled the Anomaly.
