Astronomers using several ground-based telescopes have spotted the most distant cosmic jet discovered so far. Its source is PSO J172.3556+18.7734, a radio-loud quasar located some 13 billion light-years from Earth and seen as it was when the Universe was only 780 million years old. While more distant quasars have been discovered, this is the first time astronomers have been able to identify the telltale signatures of radio jets in a quasar this early...
