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.
