Scientists discover powerful particle accelerator at heart of exploded star
An international team led by Chinese scientists has found proof that the Crab Nebula is an ultra-powerful particle accelerator that can accelerate an electron to 2.3 peta-electron volts-more than 230 times higher than the most powerful accelerator on Earth-according to a study published in the journal Science on Thursday.
Expert said the new data is approaching the theoretical limit of classical electrodynamics in astrophysics and provides key insights on the origin of ultra-high-energy particles, something that has puzzled scientists for decades. The study was led by the Chinese Academy of Sciences Institute of High Energy Physics.
