Circles of light, some small, some large, some visible, and some seen only on film.They float in the air, move around and sometimes follow unsuspecting humans around the room.
But are they evidence of ghosts?
On the night of the Carpenter Home paranormal investigation, orbs showed up on photographs taken of the front of the old mansion and surrounding one researcher on the front lawn.
Researcher William Miller says after taking thousands of orb photos, he's heard all the guesses from people on how the orbs might show up in the pictures. He says everything from dust in the air, to dirt on the camera lens, to water vapor or dew have all been put forth as possible explanations.
During the Carpenter Home investigation, The outside air temperature on November 30, 2002 was recorded at 27 degrees Fahrenheit. Miller says conditions were dry outside the mansion when the photos were taken, and that he carefully cleans his camera lenses at the start of each investigation.
Researcher Hugh Wittenbraker says he has seen orbs float over a person's head, move in straight lines and sometimes appear to follow someone around the room.
