巨大的椭圆星系梅西耶87距离我们大约5000万光年。这个巨大的星系也被称为NGC 4486，拥有数万亿颗恒星，而在我们巨大的螺旋星系中只有数十亿颗恒星。M87是室女座星系团中最大的中央椭圆星系。哈勃太空望远镜拍摄的这张清晰的光学和近红外图像显示，巨大星系核心的高能射流向外延伸了约5000光年。事实上，从伽马射线到无线电波长的电磁波谱都可以看到宇宙喷灯。它的终极能量来源是M87中心的超大质量黑洞。地球上的视界望远镜捕捉到了M87星系中央这个怪物的照片。

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.
