The Fermi Space Telescope is so sensitive to these gamma ray bursts that it doesn't even need to be positioned right over a thunderstorm to detect the TGFs.
费米太空望远镜对这些伽马射线脉冲很灵敏，以至于它甚至不需要调整位置对准雷暴的正上方，就能来探测TGF信号。
The Fermi Space Telescope found hints in 2009 of the telltale pattern associated with positrons in terrestrial gamma rays stemming from lightning storms.
费米太空望远镜在2009年就曾发现这一与正电子有关的特征现象的线索，地点正是在源于雷暴的地表伽马射线中。
