ESPRESSO has its first light on the four telescopes of the VLT at the same time

When the set of telescopes which make up the VLT was designed, one of its objectives was to be able ot use the four Unit Telescopes (UT) simultaneously as a single giant telescope with an equivalent diameter of 16m.

The IAC has collaborated in this instrument, which was one of the supported technology projects of the Severo Ochoa 2011-2015 programme. >> Read more
