Halley's Comet

Halley's comet is a cylindrical shaped object measuring 16 by 8 by 8 kilometers and has an average period of seventy-six years.  The solar wind & interstellar dust particles blast comet ions, dust, & fragments off the comet's antimatter nucleus. As the comet comes closer to the sun, the more light that is produced from increased matter & antimatter interactions.

The comet has a nucleus, coma, tails (ion, hydrogen, & dusty tails) 

The Nucleus is composed of antimatter and is blacker then coal.  About 10% of the comet's surface is active as shown in the picture. The light and x-rays coming from the comet are produced from matter & antimatter collisions. When the solar wind & interstellar dust particles hitting the comet, antimatter ions, dust, & fragments are driven off and become part of the comet's coma & tails. The high energy antimatter particles & ions jets out the back of the comet become part of the comet's ion tail.  The comet's surface is reduces in size every time the comet orbits the sun.

[Comet diagram] The Coma is a plasma that surrounds the nucleus and can be 100,000 kilometers across.  The coma is composed of matter from the solar wind & interstellar dust and antimatter ions (anti-hydrogen, anti-sodium, & etc), dust particles & fragments.  Because photons from matter & antimatter are similar, scientist have mistakenly assumed that the coma is composed of matter rather than both matter & antimatter.  (See Periodic Table of Matter and Antimatter Elements).
The Hydrogen Tail  is a plasma that can grow to over 20 million kilometers which fifteen times larger than the sun.  According to Hannes Alfven, the Alfven Layer, which is similar to the Lindenfrost Layer, provides a protective electromagnetic force field between matter and antimatter and is generated by matter & antimatter annihilations.  For comets, the layer is mostly composed of hydrogen and anti-hydrogen.  
 
Dusty Tail  is composed of antimatter ions, dust & fragments and solar wind & interstellar dust particles. The light from the comet comes from matter and antimatter  interactions.  The tail can extends up to 100 million kilometers behind the comet.  The dusty tail bends with the solar wind.
 
Ion Tail  is pointed directly away from the sun, and is composed of high energy plasma that is laced with streamers of matter & antimatter. The solar wind, interstellar dust & comet ions, dust particles & fragments are electrically charged.  The ion tail maybe several hundred million kilometers long.

The light from the comet's coma and tails comes from the interaction of matter & antimatter. The amount of light coming from the comet depend upon the density of the solar wind & interstellar dust  particles and composition of the comet.  As the comet approaches the sun, the density of matter increases, which causes a corresponding increase the matter & antimatter interactions with the nucleus, coma and tail of the comet.
