An article published in the journal “Astronomy & Astrophysics” reports a study on the blazar PSO J030947.49+271757.31, or simply PSO J0309+27, the farthest ever identified being about 12.8 billion light-years from Earth. A team of researchers led by astrophysics Cristiana Spingola of the University of Bologna and associated with the Italian National Institute of Astrophysics used the VLBA radio telescope to study PSO J0309+27, discovering details in a jet of materials ejected at about three quarters of the speed of light that spans about 1,600 light-years.
