While larger jets have been observed in the past (most notably the jet named " Porphyrion," which stretches for 23 million light-years), such monstrous emissions have mainly been associated with ...

But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...

But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...

However, astronomers have long questioned whether long, powerful jets could be spotted in the distant universe because the black holes responsible for them behaved differently in the early universe ...

If Porphyrion’s jets were only as wide as our planet, the black hole that powers them would be the size of an amoeba. However, Gloudemans’ team can only see J1601+3102’s jet as it appears at ...

The jets dubbed Porphyrion stretch for 23 million light years, equal to 140 Milky Ways lined up side by side. They erupted from a black hole that existed when the universe was half its current age.

Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light-years. That is equivalent to lining up 140 Milky Way galaxies back-to-back.

‘Porphyrion’ is 7.5 billion light-years from the Earth, which means it existed when our universe was less than half its present age of 13.8 billion years.

Astronomers have spotted two giant plasma jets streaming from a supermassive black hole in a distant galaxy. At a mind-bending 23 million light-years long, they are the longest plasma jets on ...
