By some strange coincidence, NASA has taken a photo of remnants of a star explosion which could be interpreted to look like a skeleton hand. In its wake, the explosion left a pulsar, the magnetic fields of which form a pulsar wind nebula. Because of this phenomenon, the charged particles wrap around the base of the nebula creating the resemblance of a ghostly hand.
NASA explains that the unique shape of the nebula was brought about by the high amount of polarization around MSH 15-52, thus projecting the charged particles outward in a linear fashion, which formed the fingers of the hand, meanwhile, the wrist area had more turbulent regions giving particles an energy boost and forming somewhat of a clump at the bottom.
