Porphyrion is a Fanaroff–Riley class II radio galaxy located 7.5 billion light years away from Earth, with host galaxy J152932.16+601534.4. It is located in the constellation Draco and it was discovered in Low-Frequency Array (LOFAR) data by an international team led by Martijn Oei.[2] Porphyrion has the longest jets of any radio galaxy identified, with lobed structures spanning 7 megaparsecs (23 million light-years) across, making it the largest known structure of galactic origin. It superseded Alcyoneus, discovered by the same team in 2022, with lobed structures of 5 megaparsecs (16 million light-years).[3]
