The Galactic core is obscured in visible light by dust clouds, which infrared light can penetrate.
“银河系核心在红外线可穿过的可见光中被尘埃云遮盖”是啥意思?
It orbits some 25,000 light years from the galactic core, completing a revolution once every 250 million years or so.
太阳距离银河系中心25000光年,每2亿5000万年完成一周绕银心公转。

However, some physicists believe that we don't know enough about the galactic core - or dark matter - to come to this conclusion.
然而,一些物理学家认为我们对银河核心,或者说,暗物质的认识并不全面,所以还不足以得出这个结论。
Recent surveys of the sky in near-infrared light, which penetrates the dust clouds that block our view of the galactic core, have revealed the bar directly and dispelled the remaining doubts.
近红外光可穿透挡住我们视线的尘云,而最近的近红外光巡天观测银河系核心的结果,直接显现了棒状结构,也就排除了其他的可能。
