发送到太空时设备向地面传回了一幅幅惊心动魄的景象。来自宇宙边缘明亮而短暂的伽马光束比天空中任何恒星的光芒都耀眼。它们乍然出现,只持续了几秒,然后就突然消逝了……科学家们说:“这是令人迷惑的太空火花。”地面望远镜描绘了一幅相对柔和的宇宙图景。地球的大气层和电离层把除了可见光、无线电波和红外线以外的所有辐射都阻挡在外。因此,以前的天文学家从来没有捕捉到太空中能量最大的爆炸中释放出来的高频波,直到半个世纪之前人造卫星的问世。
When sent to space, the device returned a thrilling sight to the ground. The bright, short, gamma-ray beams from the edge of the universe are brighter than the light of any star in the sky. They first appeared for only a few seconds and then suddenly disappeared ... Scientists say: “This is a mesmerizing space spark.” Earth-based telescopes depict a relatively soft picture of the universe. The Earth’s atmosphere and ionosphere block all radiation except visible light, radio waves and infrared light. As a result, former astronomers never captured the high-frequency waves released from the most energy-intensive explosions in space until the advent of artificial satellites half a century ago.
