Meanwhile, Nasa's Fermi space Telescope is taking a different approach to try to pin down dark matter. It will look for evidence of dark matter "annihilations" in space.

同时，美国太空署的费尔米太空望远镜也在使用不同的方法试图确认暗物质(的存在)。它将寻找暗物质在太空“湮灭”的证据。

The most popular theory holds that dark matter is made up of relatively heavy particles which, when they encounter one another, "annihilate" with a flash of light that the Fermi telescope can see.

Users of the Fermi space telescope have now confirmed these observations, which were first made by amateur astronomers.
