Astronomers have discovered a colossal radio jet extending 200,000 light-years from quasar J1601+3102, which formed when the universe was just 9% of its current age. This marks the largest radio jet ever observed from the early universe, measuring twice the width of our Milky Way.
This significant finding challenges our comprehension of early universe development, as these expansive jets were previously indiscernible due to cosmic microwave background radiation. It offers vital perspectives on galaxy evolution and the conditions of the early universe.
