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) and it was caused as a remnant of the Supernova (SNR) MSH 15-52.[3]. It appears approximately 1,700 years old,[4] and is located in a Pulsar wind nebula created by itself that spans about 150 light years.[5] 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." It is also known by the name "Hand of God".[6] The pulsar's spin rate is "almost 7 times per second".
X-rays from Chandra are red, green, and blue/max.
