spitting energy across 23 million light-years of intergalactic space (source
paywalled; alternative source)," writes longtime Slashdot reader fahrbot-bot.
From the report: Two jets, shooting in opposite directions, compose the biggest
lightning bolt ever seen in the sky -- about 140 times as long as our own Milky
Way galaxy is wide, and more than 10 times the distance from Earth to
Andromeda, the nearest large spiral galaxy. Follow-up observations with optical
telescopes traced the eruption to a galaxy 7.5 billion light-years away that
existed when the universe was less than half its current age of 14 billion
years. At the heart of that galaxy was a black hole spewing energy equivalent
to the output of more than a trillion stars. "The Milky Way would be a little
dot in these two giant eruptions," said Martijn Oei, a postdoctoral researcher
at the California Institute of Technology. Dr. Oei led the team that made the
discovery, which was reported in Nature on Sept. 18 and announced on the
journal's cover with an illustration reminiscent of a "Star Wars" poster. The
astronomers have named the black hole Porphyrion, after a giant in Greek
mythology -- a son of Gaia -- who fought the gods and lost. The discovery
raises new questions of how such black holes could affect the evolution and
structure of the universe.
