PSR B1509−58 is a pulsar approximately at a distance of 17,000 light-years in the constellation of Circinus discovered by the Einstein X-Ray Observatory in 1982.[3] 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.[4][5] The nebula spans about 150 light years.[6] The 0.1515 second pulsations ("6.597 times per second") are detected in the radio, X-ray, and γ-ray bands.[7]

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".[8] It is also known by the name "Hand of God".[9] This phenomenon is called pareidolia and is only temporary.

False-color image, nicknamed "Hand of God", from the Chandra X-ray Observatory (CXO), showing low-energy X-rays in red, medium-energy in green, and high-energy in blue. The pulsar (white in the center) also causes the red glowing in the neighboring hot plasma nebula RCW 89 above.[10][11]
