ESOcast 32: Most Distant Quasar Found

The astronomy podcast featuring news and cutting edge science from ESO

29 juin 2011

Quasars are extraordinarily bright distant galaxies that are thought to be powered by vast black holes at their centres. Now, a team of European astronomers has used ESO’s Very Large Telescope, and a host of other telescopes, to find the most distant of these brilliant beacons ever recorded — it is so far away that it took 12.9 billion years for its light to reach us.

In this ESOcast, Dr J explains how astronomers spent five years painstakingly searching for this object, and how its properties can help us understand the early Universe.
