X-ray & Optical Images of PSR J0357+3205
Astronomers using Chandra have found evidence for a possible long, X-ray bright tail extending from the pulsar called PSR J0357+3205 (or PSR J0357 for short). The tail seen in the Chandra dataappears to be stretching over 4 light years away from the pulsar. If this tail is indeed associated with PSR J0357, it is the longest tail ever found with a pulsar of its type. However, there are several puzzling characteristics of this system, which make astronomers eager to obtain further data.
