A Look to the Heavens- "The Hand of God Nebula"
"Red represents low-energy X-rays, the medium range is green, and the most energetic ones are colored blue. The blue hand-like structure was created by energy emanating from the nebula around they dying star PSR B1509-58. The red areas are from a neighboring gas cloud called RCW 89.

In a new image from NASA's Chandra X-ray Observatory, high-energy X-rays emanating from the nebula around PSR B1509-58 have been colored blue to reveal a structure resembling a hand reaching for some eternal red cosmic light.
The star now spins around at the dizzying pace of seven times every second - as pulsars do - spewing energy into space that creates the scene. Strong magnetic fields, 15 trillion times stronger than the Earth's magnetic field, are thought to be involved, too. The combination drives an energetic wind of electrons and ions away from the dying star. As the electrons move through the magnetized nebula, they radiate away their energy as X-rays."
