PSR J1747-2958 is a young, weak, nonthermal radio pulsar with a rotation period of 98.8 ms (milliseconds). The pulsar moves at a supersonic speed through the interstellar medium forming an unusual nonthermal nebula around it. This nebula around PSR J1747-2958 is also called the "Mouse nebula" or "G359.23-0.82" and it is a axisymmetric nebula.[1]

Discovery

This object was discovered in February 7, 2008, with a 58 ks exposure.[2]
