Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy. Black holes eat most space debris that falls their way.

The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy,

"If we shrink the jets to the size of the Earth and the black hole accordingly, the black hole would have the size of 0.2 millimeters: the size of an amoeba or a mite on your skin. So these giant jets are incredible: they are as if a single amoeba was able to generate a powerful fountain of energy the size of the entire Earth!"
