• Resumen

  • This article focuses on the research being done on lightning. To generate lightning forming runaway electrons, Alexander V. Gurevich used a brute-force method in which the electric field is so incredibly strong that some of the low-energy electrons are quickly accelerated up and over the energy threshold, allowing them to run away. Scientists finally found a direct link between x-rays and lightning in 2001, when Charles B. Moore and his co-workers at NMT reported observing energetic radiation, presumably x-rays, from several natural lightning strikes on top of a tall mountain. INSET: THE BRIEF LIFE OF LIGHTNING.
