Telescopes around the world have spotted a monster radio jet streaming from a quasar dating back to the first 1 billion years of the universe.

From decades of astronomical observations, scientists know that most galaxies contain massive black holes at their centers. The gas and dust falling into these black holes liberates an enormous amount of energy as a result of friction,

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.
