At the heart of that galaxy was a black hole spewing energy equivalent to the output of more than a trillion stars. ......... The astronomers have named the black hole Porphyrion, after a giant in Greek mythology — a son of Gaia — who fought the gods and lost. ........ “Porphyrion shows that small things and large things in the universe are intimately connected,” Dr. Oei added. If the jet was shrunk to the size of the Earth, the black hole would be just two-tenths of a millimeter across. “These giant jets are really incredible,” he said. “They are as if a single amoeba was able to generate two powerful streams of energy the size of Earth.” ......... Paradoxically, black holes — cosmic pits from which not even light can escape — can be the brightest objects in the universe. .......... In 2022, the team announced that they had found a plume of plasma 16 million light-years long, roughly the width of 100 Milky Ways. They named it Alcyoneus, another ancient Greek giant that fought the gods (unsuccessfully) for supremacy over the cosmos. It was the record-holder until Porphyrion. ........... So far, after surveying about 15 percent of the sky, Dr. Oei’s project has found 8,000 jets longer than about three million light-years. By the time it is done, he said, his team might find as many as one million giant jets between Earth and Porphyrion.
