Last week, we shared the extremely good news that a piece of glass-ceramic had been cast for the secondary mirror of the European Southern Observatory's (ESO) Extremely Large Telescope. And now we have more good news! Construction has also begun on the telescope's primary mirror, which will be 39 meters (128 feet) in diameter and is composed of 798 individual hexagonal segments. http://buff.ly/2sjxYC4 | Space.com
