Hand of God


NASA's space telescope NuSTAR captures the image of a celestial object that resembles a big hand. Astronomers name this as “The Hand of God”

The celestial object is a the nebula, consisting a pulsar, 17,000 light-years away from us. The nebula was produced when a star exploded at the end of its life and ejected an enormous cloud of material. †The radius of the pulsar is 19 kilometres and it spins around nearly seven times every second.

NuSTAR, glimpsed in high-energy X-rays, shown in blue in the photo. NASA's Chandra X-ray Observatory had imaged the green and red parts previously, using lower-energy X-rays.

As these particles interact with nearby magnetic fields, they produce an X-ray glow in the shape of a hand. (The pulsar is located near the bright white spot in the image but cannot be seen itself)

Scientists aren't sure whether the ejected material actually assumes the shape of a hand, or whether its interaction with the pulsar's particles is just making it appear that way.

"We don't know if the hand shape is an optical illusion," Hongjun An, of McGill University in Montreal, said in a statement. "With NuSTAR, the hand looks more like a fist, which is giving us some clues."

The red cloud appearing at the fingertips is a separate structure called RCW 89. The pulsar's wind may be heating the cloud to produce the low-energy X-ray glow, astronomers believe.

The X-ray energies seen by NuSTAR range from 7 to 25 kiloelectron volts, or keV, whereas the energies seen by Chandra range from 0.5 to 2 keV.

The Hand of God is an example of pareidolia, the psychological phenomenon of perceiving familiar shapes in random or vague images. Other common forms of pareidolia include seeing animals or faces in clouds, or the man in the moon. Despite its supernatural appearance, the Hand of God was produced by natural astrophysical phenomena.
