Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.

Opposing fountains of plasma and particles spanning 23 million light-years are the longest pair of black hole jets ever seen. That’s far enough to influence the evolution of the universe on ...

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light- years.

Astronomers have discovered a black hole emitting energy in jets longer than the width of 140 Milky Way galaxies. An artist’s concept of Porphyrion, a jet of material 23 million light-years long ...

Porphyrion’s twin jets came from a supermassive black hole at the heart of a galaxy that’s a dizzying 7.5 billion light-years away from Earth.

Named Porphyrion (another one of those Greek giants), these jets originate from a black hole roughly 7.5 billion light-years from Earth. And they pack quite the punch, delivering a power output ...
