天文学家探测高能宇宙射线粒子,暗示近处的天体源。 Astronomers detect highest-energy cosmic-ray particles, hinting at nearby celestial sources.

运用H.E.S.S.的天文学家 Astronomers using the H.E.S.S. 纳米比亚观测站已探测到有史以来记录到的最有活力宇宙射线电子和正电子,其能量可高达40兆赫。 Observatory in Namibia have detected the most energetic cosmic-ray electrons and positrons ever recorded, with energies up to 40 teraelectronvolts. 这些高能粒子可能来自数千光年之内的附近来源,可能来自脉冲星或其他稠密天体。 These high-energy particles likely originate from nearby sources within a few thousand light-years, possibly from pulsars or other dense celestial objects. 超过一个兆位电子伏的能源急剧下降表明有数量有限的能源来源。 The sharp drop in energy beyond one teraelectronvolt suggests a limited number of sources.
