Edward Purdy Ney was an American physicist who made major contributions to cosmic ray research, atmospheric physics, heliophysics, and infrared astronomy. He was a discoverer of cosmic ray heavy nuclei and of solar proton events. He pioneered the use of high-altitude balloons for scientific investigations and helped to develop procedures and equipment that underlie modern scientific ballooning. He was one of the first researchers to put experiments aboard spacecraft.
At center right, a primary cosmic ray heavy nucleus goes vertically through a cloud chamber, which was suspended under a balloon near the top of the atmosphere. At left, a Helium nucleus enters through the side of the chamber. Thin tracks are singly charged particles moving at nearly the speed of light. Note that this is a negative image, in which white droplets appear black, and that the horizontal bars are electrodes that do not introduce any material into the chamber.
