巨大的橢圓星系 Messier 87 位於大約 5000 萬光年之外。這個巨大的星系也被稱為 NGC 4486 ,它擁有數萬億顆恆星,而我們的大螺旋星系銀河中只有數十億顆恆星。M 87 是室女座星系團中的大型中央橢圓星系。從哈勃太空望遠鏡拍攝的這幅清晰的光學和近紅外影像中,我們可以看到來自巨型星系核心的高能噴流向外延伸了大約 5000 光年。事實上,從伽馬射線到射電波長的電磁波譜中都能看到宇宙噴射火炬的身影。它的最終能量來源是 M 87 中央的超大質量黑洞。地球上的地平線事件望遠鏡捕捉到了 M 87 中央這個怪物的影像。
原文:rmous elliptical galaxy Messier 87 is about 50 million light-years away. Also known as NGC 4486, the giant galaxy holds trillions of stars compared to the mere billions of stars in our large spiral Milky Way. M87 reigns as the large central elliptical galaxy in the Virgo galaxy cluster. An energetic jet from the giant galaxy's core is seen to stretch outward for about 5,000 light-years in this sharp optical and near-infrared view from the Hubble Space Telescope. In fact, the cosmic blow torch is seen across the electromagnetic spectrum from gamma-rays to radio wavelengths. Its ultimate power source is M87's central, supermassive black hole. An image of this monster in the middle of M87 has been captured by planet Earth's Event Horizon Telescope.
