From end to end, these gargantuan jets measure 140 times the diameter of the entire Milky Way.
The largest-ever pair of radiation jets has been discovered bursting out of a distant supermassive black hole, burning brighter than 100 galaxies, or over a trillion stars.From the end of one jet to the end of the other, the pair measures roughly 7 megaparsecs or about 23 million light-years, making them the longest jets ever found, according to a new paper in the journal Nature.
The type of black hole that the jets are being shot out from indicates that it is very old, and the jets themselves are thought to have been burning since the universe was 6.3 billion years old, less than half its current age of 13.8 billion years.
