Astronomers announced on Wednesday that at last they had seen the unseeable: a black hole, a cosmic abyss so deep and dense that not even light can escape it.
The image, of a lopsided ring of light surrounding a dark circle deep in the heart of the galaxy known as Messier 87, some 55 million light-years away from here, resembled the Eye of Sauron, a reminder yet again of the power and malevolence of nature. It was a smoke ring framing a one-way portal to eternity.
To capture the image, astronomers reached across intergalactic space to a giant galaxy in Virgo, known as Messier 87. There, a black hole about seven billion times more massive than the sun is unleashing a violent jet some 5,000 light years into space.
