Antimatter Sungrazer Comets
Comets have been observed for centuries and sometimes they split into smaller ones, known as sungrazers. The antimatter sungrazers are classified into families. The Kreutz family contains several hundreds sungrazers that less than a hundred meters in diameter. Kamikaze sungrazers collide with the sun and produce gigantic explosions. The X-class solar flares turn out gamma and x-rays from that can cause communication blackouts around the world.
On July 23, 2002, researchers using NASA's RHESSI spacecraft took pictures of solar flare's gamma and x-ray radiation, which is millions to billions of times more energetic than visible light. After the initial explosions, the lingering metric ton of antimatter could have powered the United States for two years. The 23,000 metric ton, 30 meters in diameter antimatter sungrazer created a billion Megatons of TNT explosion that could have supplied the World's total energy needs for 10,000 years.

On November 4, 2003, physicists observed a record-breaking X-45 class solar flares. The movies show the solar explosions and flares from the antimatter sungrazer that collided with the sun. The solar flares produced x-ray radiation that was equivalent to 5,000 Suns.
