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] It appears approximately 1,700 years old,[3] and it sits in a nebula that spans about 150 light years.[4] 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".[5] The spin rate is "almost 7 times per second".
X-rays from Chandra are red, green, and blue/max.
