The term orb is used to describe balls of light, usually captured on digital cameras. Orbs can be any colour but are usually white. Many paranormal investigators believe them to be the spirits of the dead. Others believe that they are dust particles, water droplets or insects caught in the flash of a camera. Orbs could also be caused by lens flares or even damage to the camera. I would say that the majority of orbs can be explained away as any of the above.
Here are two examples. The first was taken in Framlingham churchyard, Suffolk. The second was taken in a house in Stonebow, York.
