What are the largest galaxy-made structures in the Universe? ℹ️Astrophysical jets are collimated streams of magnetized plasma produced by compact accreting objects, e.g. neutron stars or black holes. When sustained for megayears (such long-lived coherence being yet unknown), these jets from supermassive black (SMBHs) holes become the largest galaxy-made structures in the Universe. Named Porphyrion, after the king of giants in Greek mythology, the jets: 🌌stretch for around 23 million light-years – as long as 140 Milky Way galaxies 🌠are born at the heart of a galaxy located around 7.5 billion light-years away and are seen as they were when the 13.8 billion-year-old universe was just 6.3 billion years old 🔥put out trillions of times more energy per second than our sun does. 🌐 In terrestrial dimensions, this SMBH would have the size of 0.2 millimeters and the jets – the size of the Earth: an amoeba that generates a powerful fountain of energy the size of the entire planet!
