Largest radio jet ever seen in the early universe

Astronomers have discovered the largest radio jet in the early Universe, spanning 200,000 light-years. The jet, from quasar J1601+3102, formed when the Universe was under 1.2 billion years old. Using multiple telescopes, researchers observed this massive jet and its source quasar, which has a mass 450 million times that of the Sun. This discovery challenges assumptions about conditions necessary for powerful jets in the early Universe and provides insights into the formation and impact of the first large-scale jets.
