"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, the
Milky Way.
In 2022, we announced the discovery of one of the largest black hole jets in
the night sky, launched from a (relatively) nearby galaxy called NGC2663. Using
CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) in Western
Australia, we confirmed that NGC2663’s jet is one of the largest in the sky. In
other words, it appears to be the largest when viewed from Earth.
The new jet, announced in the journal Nature, has been dubbed “Porphyrion” (a
giant in Greek mythology) by its discoverers at the California Institute of
Technology in the United States. It dwarfs NGC2663’s jet in actual size and is
over 20 times larger – a true colossus.
Porphyrion can tell us more about the great ecosystem of matter flowing inside
and outside of galaxies. But this jet also has us scratching our heads: how can
something 23 million light years across be almost perfectly straight?"
