On January 3rd, 2010, the SOHO satellite captured images of a comet disintegrating as it approached close to the Sun. The comet was what's known as a "Sungrazer" -- comets whose orbits lead them very near the Sun. Although one would not get the impression from science news reports on the comet, Sungrazers present an unresolved puzzle for astronomers. [More...]

The conclusion is incorrect. Pressure and heat are not the only phenomena producing diamonds.http://www.sott.net/articles/show/17469 ... Panhandle-
Did a comet strike Earth, leaving crystalline dust in the Oklahoma Panhandle?
A giant comet slammed into the atmosphere and fractured. The resulting swarm of fragments also exploded, scattering tiny diamonds in widely separated locations and plunging the warming Earth into a renewed and deadly deep freeze.
By firing X-rays through the remaining material, the comet researchers found what they were looking for, "nanodiamonds" a millionth of a millimeter across, so small 1 billion would be only the size of a sugar cube. Such carbon structures cannot be created by any natural forces on Earth, Bement said. Only the pressures and heat from something like a comet burst could produce them.
The following link suggests a correlation between lowdensity hydrocarbon plasma and diamond layer formation.
It is ofcourse speculation from my part.http://www.turpion.org/php/paper.phtml? ... er_id=3061
Heterogeneous and homogeneous processes in the formation of diamond at low pressures, where diamond is a metastable modification of carbon, are discussed. Data on the kinetics of the growth of diamond from hydrocarbons under conditions which give codeposition with graphite are reported, together with data on the influence of hydrogen on this process and on the resulting fractionation of the stable carbon isotopes. Chemical and plasma-chemical methods of preparing diamond and diamond-like layers are discussed, as well as methods based on the use of atomic and ionic beams. The most recent theoretical and experimental results on the homogeneous formation of diamond in the gas phase are presented.
Message for Admin Dave. I could not find the original - electric comet - post. Could you put this message there if possible?
