This four-panel graphic shows the two pulsars, Geminga (upper left) and B0355+54 (upper right), observed by Chandra. In both of these images, Chandra's X-rays, colored blue and purple, are combined with infrared data from Spitzer that shows stars in the field of view. Below each data image, an artist's illustration depicts more details of what astronomers think the structure of each pulsar wind nebula looks like. New Chandra data on the shape of these structures may explain the presence or absence of radio and gamma-ray pulses.
