The Quipu superstructure is enormous, spanning 1.4 billion light years – and it could violate one of our fundamental assumptions about the universe

These jets become elusive the farther back in time astronomers try to look because of the so-called cosmic microwave background. The ancient radiation, the earliest fossil of light from 380,000 years after the Big Bang, tends to swamp out more subtle signals.

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the largest known structure in the universe in terms of length, scientists claim.

Researchers said on Thursday that they had discovered twin-lobed radio jets they suspect were formed when the universe was 1.2 billion years old, stretching at least twice the length of the Milky Way galaxy.

Astronomers have detected an enormous black hole-powered jet that stretches an astonishing 200,000 light-years, making it twice as long as the Milky Way. This colossal cosmic jet, erupting from the quasar J1601+3102,

By revealing a massive radio jet in the early universe, J1601+3102 offers a rare snapshot of early quasar activity.
