Either way, one sign of dark matter particles, researchers think, is a burst of annihilation-induced gamma rays.

科学家们认为，无论是这两种解释的哪一种，暗物质颗粒的一种标志是粒子湮没爆发出的伽马射线。

Every so often the sun emits a gigantic burst that includes highly energized x-rays gamma rays and charged particles.

太阳偶尔放射出包括高能量x射线、伽马射线，和带电粒子。

Explanation: A symphony of planet-wide observations began abruptly on March 28 when the Earth-orbiting Swift satellite detected a burst of high-frequency gamma-rays from GRB 110328A.

解说： 一场世界规模的观察交响曲在 3 月 28 日突然开始了，当时环绕地球的 Swift 卫星监测到了来自 GRB 110328A 的高频伽马射线爆发。

When a supergiant finally goes bang it produces a massive burst of gamma rays and that burst lasts much longer because the supergiant is so big and there's much more fuel to burn through.

And that depends on being able to see the lower-energy radiation, in order to pinpoint what it was that exploded (gamma rays are impossible to focus, so the location of a burst is known only approximately).
