Kirlian Photography: Revealing Nature’s Electrical Aura 

Kirlian photography is the term used to describe the techniques used to capture the phenomenon of electrical coronal discharges. It is named after Semyon Kirlian, a Russian electrical engineer, and his wife Valentina, who in 1939 discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate. They developed Kirlian photography after observing a patient in Krasnodar hospital who was receiving medical treatment from a high-frequency electrical generator. When the electrodes were brought near the patient’s skin, they noticed a glow similar to that of a Neon Discharge Tube. Afterwards, the Kirlians conducted experiments in which photographic film was placed on top of a conducting plate, and another conductor was attached to the a hand, a leaf or other plant material. The conductors were energized by a high frequency high voltage power source, producing photographic images typically showing a silhouette of the object surrounded by an aura of light. Though the Kirlians reported the results of their experiments in 1958, their work remained virtually unknown until 1970, when two Americans, Lynn Schroeder and Sheila Ostrander published a book, Psychic Discoveries Behind the Iron Curtain. While Kirlian photography has been the subject of mainstream scientific research, it has largely been co-opted by promoters of pseudoscience, parapsychology, and paranormal health claims. In many ways, the technique has effected greater mass influence because of these associations, and speaks to the ways “energy-culture” enters popular thought. 


Durante las últimas tres semanas, las aguas del Golfo de México se vieron surcadas por un barco como ningún otro: el Okeanos Explorer, dedicado a descubrir los misterios más profundos del océano

A través de vehículos operados remotamente, el Okeanos transmitió en vivo algunos de las vídeos marinos más sorprendentes que se han visto en los últimos años. Puedes echarles un vistazo a través de estos gifs que Popular Science ha creado.

También puedes sumergirte varios metros por debajo del mar gracias a las hazañas del Okeanos y maravillarte con lo que oculta el Golfo de México.
