Black hole jets are powerful streams of particles and magnetic fields ejected from the regions surrounding supermassive black holes. These jets, often spanning hundreds of thousands of light-years, play a crucial role in shaping the environments around galaxies by injecting energy into the intergalactic medium.

NEW YORK (AP) — Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy. The jets shooting hot plasma are the largest ever spotted – about as long as 140 Milky Way galaxies lined up end-to-end.

The plumes stretch farther than any yet seen, reaching millions of light-years long and potentially influencing the cosmos nearby.
