These particles, when interacting with magnetic fields around the material, result in the glow with X-rays, resulting in a cloud that resembles that of an open hand.
Scientists are still trying to understand whether it’s the pulsar particles interacting with the material in a certain way to create the shape of the hand or if the material itself is shaped like a hand.
According to NASA, when the NuSTAR space X-ray telescope captured the image, the hand appears to have shrunk and it looks more like a fist.
