Astronomers used an array of telescopes to find the most massive radio jet in the early universe. The celestial object is hundreds of thousands of light-years long.

While radio jets are relatively common in the nearby Universe, they have been elusive in the early Universe. This is partly due to the cosmic microwave background (CMB), the faint afterglow of the Big Bang. The CMB creates a persistent fog of microwave radiation that can drown out the faint radio signals from distant objects.

Researchers say they've discovered the largest known object in the universe, a galactic superstructure called Quipu.
