PSR B1509-58 is a pulsar approximately 17,000 light-years away in the constellation of Circinus discovered by the Einstein X-Ray Observatory in 1982.[1] It is approximately 1700 years old[2] and sits in a nebula that spans about 150 light years.[3] NASA described the star as "a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand." [4] Spin rate is "almost 7 times per second".
