Visit the Quest for the Invisibles You Tube channel, where you can watch a selection of videos featuring infrared and ultraviolet footage showing various invisible life-forms, captured at my research area near Oxford. Take a look at the Hidden Reality series of videos, which feature bizarre life-forms such as the "Spinning Jennys" and the "Plasmatic Gliders," as well as a whole host of other strange objects, which were all captured using readily available equipment. You can also listen to extracts taken from BBC Radio Oxford's Malcolm Boyden show, where Nik Hayes discusses his work with Quest for the Invisibles, along with the work of infrared UFO pioneer Trevor James Constable, and the reality of invisible biological UFOs in the skies over Oxfordshire.

From the fall of 1974 to 1980, a strange series of events took place in Florida, USA, in the village of Palm Springs. After experiencing some minor acts of vandalism, Gregory Harold installed a Kodak Super 8 security camera in his back garden, hoping to identify the culprits responsible, and bring it to an end. Upon reviewing the footage he discovered numerous strange images, including small helmeted beings, alien-like creatures as well as moving balls of light. Intrigued by this, Greg continued filming for another six years, and his subsequent books The Alien Connection and Gods of Religions feature many of these amazing images, along with a detailed analysis of each photograph. The DVD Harold's Mystery also covers the whole story including original film clips, again providing evidence of a hidden reality existing all around us. The books and DVD are available from Amazon, or can be ordered from any good book retailer.


Gregory Harold's classic book The Alien Connection has just been re-published. This second re-worked and much updated edition of the book is now available from Amazon, and can also be ordered from any good bookstore.
