An X-ray nebula that spans 150 light years is seen along with the pulsar that caused it in this image taken by the Chandra X-ray Observatory satellite and released by NASA April 3, 2009. This pulsar with a diameter of 12 miles, is spinning around almost 7 times a second and has a magnetic field at its surface estimated to be 15 trillion times stronger than the Earth's magnetic field. This combination of rapid rotation and ultra-strong magnetic field drives an energetic wind of electrons and ions, ultimately creating the elaborate nebula seen by Chandra. [NASA]

What appears, with a little imagination, to be the outstretched fingers were created by a spinning neutron star known as a pulsar buried deep inside the fist, which releases energy as it rotates.
Although the pulsar itself is only 12 miles in diameter, the cloud or nebula that it produces stretches across 150 light years of space.
The X-ray image was recorded by Nasa's Chandra observatory which is circling 360 miles above Earth taking images of high-energy locations across the universe, such as the remnants of exploded stars.
Dubbed the Hand of God, following on from an 'Eye of God' image released by European astronomers in February, the nebula pictured in the new X-ray was produced by the pulsar B1509, which is about 17,000 light years away.
Neutron stars are created when standard stars run out of fuel and collapse, and Nasa believes that the one pictured is rotating around seven times a second.
The golden-red lights in the image are actually part of a neighbouring gas cloud, which has been energised by the wind of electrons and ions being spewed out from the pulsar.
The colours of the image represent different energy intensities – the blue lights are the areas of highest energy X-rays, followed by green and then red.
This is a picture taken by NASA with the Hubble telescope in 2003. They are referring to it as the "Eye of God". What it actually depicts is the so-called Helix Nebula, described by astronomers as "a trillion-mile-long tunnel of glowing gases." At its center is dying star which has ejected masses of dust and gas to form tentacle-like filaments stretching toward an outer rim composed of the same material.
