Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. CRTF has 220 mirrors each over 7-meters in diameter all focused on a single tower. CRTF's main use is to investigate methods of collecting and using solar power . CRTF does not create focussed sky images like a normal astronomical telescope , but collects light from a much larger area. Photons in this range might allow further exploration of enigmatic gamma ray burst explosions, and might be emitted when cosmic rays from supernovae impact gas clouds in the interstellar medium .
