ESOcast 22: The Most Distant Galaxy Ever Measured
The astronomy podcast featuring news and cutting edge science from ESO
21 October 2010
An international team of astronomers using ESO’s Very Large Telescope has measured the distance to the most remote galaxy known so far. This is the first time that scientists have been able to confirm that they are observing a galaxy as it was in the era of reionisation — when the first generation of brilliant stars stripped out the opaque hydrogen fog filling the young Universe, thus making it transparent and ending the cosmic Dark Ages.
In the latest ESOcast host Dr J explains how the historic observations were made, and the science that can be learned from them.
The ESOcast is available in multiple formats, including HD. Episodes can also be watched or downloaded directly from iTunes.
