天文学家在银河系首次探测到暗物质踪迹

‘Decade of dark matter＇ begins

一些科学家说，未来的十年将是暗物质的十年．而探测这种神秘物质的结果要么获得成功．要么便是排除关于暗物质到底是什么的最有希望的假设。但是两位天体物理学家表示，天文学家或许已经在我们自己的银河系中央探测到暗物质的信号。

The coming decade will be the decade of dark matter, some scientists say, as efforts to detect the mysterious stuff will either pay off or rule out the most promising hypothesis about what it is. However, astronomers may have already detected signs of dark matter in the heart of our own Milky Way galaxy, a pair of astrophysicists now say.
