Funny how assorted psychics have known this for thousands of years. Next they'll be able to show you that the colors change with mood and stress. Hmmm.

Back in the '80's, some 'New Age'-kinda babe told me that my 'aura' was orange, Jim! Can you see it?! ;-)

We're even more awesome than I thought! Thank you Jim.

I just wonder if any creatures out there ARE able to detect human bio-luminescence, or each other's, creatures we don't already know can do so.

...yes we do... it's called the "aura"

I've studied this before in physics IT'S NOT A VISIBLE LIGHT .it's wrong to say visible light it's invisible we can detect it by special cameras called night vision system.Our bodies emits radiations in the form of infrared which gives you heat (when you cover your self with a blanket at winter it traps infrared so you feel warm) and appears glowing by night vision system.You have to know that in order to have an invisible light so your temprature should be at least 3000k as an incandecent lamp or 6000k as sun BUT our body temprature is 310k only which not enough to emit light(photon) so that the eye(very sensetive to photons) can pick it.BUT AT LAST i SHOULD ADMIT IT'S VERY COOOOOOL!!!!!;D

1) Very interesting. To some animals with the appropriate receptors, we must look like glow worms... 2) "Bioluminescence is the production and emission of light by a living organism. Its name is a hybrid word, originating from the Greek bios for "living" and the Latin lumen "light". Bioluminescence is a naturally occurring form of chemiluminescence where energy is released by a chemical reaction in the form of light emission. Adenosine triphosphate (ATP) is involved in most instances. The chemical reaction can occur either inside or outside the cell. In bacteria, the expression of genes related to bioluminescence is controlled by an operon called the Lux operon. Bioluminescence has appeared independently several times (up to 30 or more) during evolution. Bioluminescence occurs in marine vertebrates and invertebrates, as well as microorganisms and terrestrial animals. Symbiotic organisms carried within larger organisms are also known to bioluminesce."

"Kirlian photography refers to a form of photogram made with a high voltage. It is named after Semyon Kirlian, who in 1939 accidentally discovered that if an object on a photographic plate is connected to a source of high voltage, small corona discharges (created by the strong electric field at the edges of the object) create an image on the photographic plate. Kirlian's work, from 1939 onward, involved an independent rediscovery of a phenomenon and technique variously called "electrography", "electrophotography", and "corona discharge photography". The Kirlian technique is contact photography, in which the subject is in direct contact with a film placed upon a metal plate charged with high voltage, high frequency electricity. The underlying physics (which makes xerographic copying possible) was explored as early as 1777 by Georg Christoph Lichtenberg (see Lichtenberg figures). Later workers in the field included Nikola Tesla; various other individuals explored the effect in the later 19th and early 20th centuries. Kirlian made controversial claims that the image he was studying might be compared with the human aura. An experiment advanced as evidence of energy fields generated by living entities involves taking Kirlian contact photographs of a picked leaf at set periods, its gradual withering being said to correspond with a decline in the strength of the aura. However it may simply be that the leaf loses moisture and becomes less electrically conductive, causing a gradual weakening of the electric field at the drier edges of the leaf. In some experiments, if a section of a leaf was torn away after the first photograph, a faint image of the missing section would remain when a second photograph was taken. The Archives of American Art Journal of the Smithsonian Institution published a leading article with reproductions of images of this phenomenon. James Randi has suggested that this effect was due to contamination of the glass plates, which were reused for both the "before" and "after" photographs."

The depiction of such an aura in religious art usually connotes a person of particular power or holiness. According to the literature of Theosophy, Anthroposophy, and Archeosophy, each color of the aura has a precise meaning, indicating a precise emotional state. A complete description of the Aura and its colors was provided by Charles Leadbeater, a theosophist of the 19th century. The works of Leadbeater were later developed by Palamidessi and others. Skeptics such as Robert Todd Carroll contend that auras may be seen for explainable reasons such as migraines or synesthesia. Some people see auras as the result of a migraine, epilepsy, a visual system disorder, or a brain disorder. Eye fatigue can also produce an aura, sometimes referred to as eye burn."

That isn't light. That's an image taken by a Thermographic camera. No, the body does not emit visible light, if it were so, you could see somebody when it's pitch black. Rule #1 for the rest of your life: DO NOT, I repeat DO NOT believe something just because a "researcher" a "doctor" or a "scientist" had said so. Make sure you do all your own research, check their method of testing this research and look at all the data available, there are many many liars out there.
