SUMMARY: The Hubble Space Telescope took this amazing picture of the Crab Nebula supernova remnant. The star at the heart of the nebula exploded as a supernova nearly 1,000 years ago, and was recorded by Chinese astronomers as being bright enough to be visible during the day. This photograph was built up from 24 individual Wide Field and Planetary Camera 2 exposures taken over several years.

May be there is something electrical in it because it look like a Lichtenstein figure from the Anthony Peratt Site.

There are also some distinctly "electrical" things in the accompanying Hubblesite commentary: the "dynamo powering the nebula's eerie interior bluish glow" and the follow-up explanation that the blue light comes from "electrons whirling at nearly the speed of light around magnetic field lines" (i.e. an electric current). Does gravity still have a role to play or has the paradigm already shifted far enough to make it redundant?

Of course, the "dynamo" image was already explicitly suggested by the remarkable Chandra image (http://chandra.harvard.edu/photo/0052/) dated as far back as August 29, 1999.
