orbs

An orb is a spherical object or shape. The term comes from the Latin orbis, meaning circle or disk, and is used across fields to denote a three-dimensional sphere or something approximating one.

In science and nature, spheres are common forms in both macro and micro scales. Planets and stars can be described historically as orbs, and particles such as droplets, bubbles, pollen grains, and cells often occur in nearly spherical shapes.

In culture, the word appears in heraldry and symbolism. The Globus cruciger, an orb topped with a cross, is a traditional symbol of royal authority and Christian dominion over the world. In folklore and occult contexts, "orbs" are sometimes described as glowing spheres linked to spirits or supernatural phenomena; such accounts are subjective and vary by tradition.

In photography and media, orbs are a common term for circular light artifacts captured by cameras. They usually result from out-of-focus points of light reflecting off dust, moisture, or lens surfaces, and not from spirits. Some paranormal researchers discuss orbs as potential evidence; mainstream science regards most as photographic artifacts or misinterpretations.
