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。

So when we detect gamma-rays from space, we know they signal intensely hot, extreme events.

CNN: Why gamma-ray burst shocked scientists

Now, an international team of astronomers has trained the Fermi space-based gamma ray telescope on V407 Cygni, a "binary" system comprising a white dwarf star and a red giant companion, 9, 000 light-years away.

Many Americans recognize the unsurpassed science and inspiration that have come from the Hubble Space Telescope over the past two decades, as well as from its less famous sister satellites like the Chandra X-ray Observatory, the Spitzer Space (Infrared) Telescope and the Fermi gamma-ray observatory.
