"One of the reasons we are interested in VHE gamma rays is because they act as tracers for high energy particles
known as cosmic rays.
Astrophysical sources of high energy particles
and radiation; proceedings.
During this process very high energy particles
will collide at over 800 million times a second.
Context:Solar flares are dramatic and complex events, which give off electromagnetic radiation in almost all wavelength bands across the spectrum, and also directly emit high energy particles
The purpose of the mission is to obtain more knowledge about how comets interact with the high energy particles
blasted by the Sun into space that are known as the solar wind.
Last month Mars Express, launched into space by a Russian rocket on June 2, weathered a solar storm caused by high energy particles
from eruptions on the sun.
