ESOcast 234 Light: Most distant quasar with powerful radio jets discovered

Published: March 8, 2021, 1 p.m.

With the help of ESO’s Very Large Telescope, astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a “radio-loud” quasar — a bright object with powerful jets emitting at radio wavelengths — that is so far away its light has taken 13 billion years to reach us. This video summarises the discovery.
