这张由哈勃望远镜拍摄的NGC1275星系照片完美的展现了其丝状结构。在Perseus星系群中心的红色细丝是由较冷的气体在磁场作用下组成并被华氏100万度的炙热气体所包围。细丝是中央巨型黑洞将其能量转移到周围气体这一反馈过程的明显标志。细丝源,冷气体通过射线泡从星系中央区域被运送上升到炙热的星级气体区域。在远处230百万个光年, NGC1275年是其中一最接近的巨型椭圆星系并且位于Perseus星系群中心。
此星系是在7月份you一台先进的三色滤色相机拍摄。
This Hubble Space Telescope image of galaxy NGC 1275 reveals the fine, thread-like filamentary structures in the gas surrounding the galaxy. The red filaments are composed of cool gas being suspended by a magnetic field, and are surrounded by the 100-million-degree Fahrenheit hot gas in the center of the Perseus galaxy cluster.
The filaments are dramatic markers of the feedback process through which energy is transferred from the central massive black hole to the surrounding gas. The filaments originate when cool gas is transported from the center of the galaxy by radio bubbles that rise in the hot interstellar gas.
At a distance of 230 million light-years, NGC 1275 is one of the closest giant elliptical galaxies and lies at the center of the Perseus cluster of galaxies.
The galaxy was photographed in July and August 2006 with the Advanced Camera for Surveys in three color filters.
