Appearance & Characteristics: Orbs are the most photographed anomalies captured on film by ghost hunters. They most often show up as transparent or translucent balls of light hovering above the ground. Another feature is  when they are captured on film they have a lingering trail.

This trail indicates they were traveling at a fairly fast rate of speed at the time of the flash, which further indicates it's authenticity. Some experts say that 85% of photographed orbs are created inadvertently by circumstances and weather conditions at the time of the flash.

Orbs have also been seen on video hovering in the same position for short periods of time but most often are caught traveling erratically through the air in a rather care free pattern.

Locations spotted; They have been seen in every location imaginable. Temperature changes and different climates do not seem to affect them. They are most often seen outdoors and especially seem to be drawn to historic surroundings.

Present Theories; Believed by many to be the soul or spirit  of those that have passed on from this life. Some theories claim that a orb is the basic form of all ghostly phenomena. From this state they change into ecto-mist and then apparations.

They are known to emit small electro-magnetic fields. There are other theories about orbs as well. One would be that they are a separate life form all together and are undetectable to the human eye  because of their finer tissue.
