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.[2] Its diameter is only 12 miles (19 km). It is located in a Pulsar wind nebula created by itself, that was caused as a remnant of the Supernova (SNR) MSH 15−52 visual approximately 1,700 years ago at the southern celestial hemisphere not visible in the northern hemisphere.[3][4] The nebula spans about 150 light years.[5] The pulsar's spin rate is "almost 7 times per second".

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".[6] It is also known by the name "Hand of God".[7] This phenomenon is called pareidolia.
