 E-Mail Astronomers using the National Science Foundation s Karl G. Jansky Very Large Array (VLA) and Very Long Baseline Array (VLBA) have found and studied the most distant cosmic jet discovered so far a jet of material propelled to nearly the speed of light by the supermassive black hole in a quasar some 13 billion light-years from Earth. The quasar is seen as it was when the universe was only 780 million years old, and is providing scientists with valuable information about how galaxies evolved and supermassive black holes grew when the universe was that young. The studies indicate that the quasar a galaxy harboring a black hole 300 million times more massive than the Sun has a jet of fast-moving particles only about 1,000 years old. While other quasars have been found at its distance and beyond, it is the first found at such a distance with the strong radio emission indicating an active jet. Only a small fraction of quasars have such jets.
