Cerro Paranal (middle right) and Cerro Armazones (middle left)
ESO announced today that their Council have recommended Cerro Armazones in the Chilean Andes as the preferred site for their next generation optical/IR observatory, the 42-m European Extremely Large Telescope. The decision came in response to the delivery of a technical report by the organisation’s E-ELT Site Selection Advisory Committee, from which Armazones emerged as the frontrunner, “because it has the best balance of sky quality across all aspects and it can be operated in an integrated fashion with the existing ESO Paranal Observatory”.
So does this means the deal is done? Apparently not. The text also tells us that ESO have received proposals to host the telescope from both Spain, who would like to see the telescope site on La Palma, and Chile, so a final run-off between these two countries now seems likely.
What has struck me about this whole site selection exercise is the different approaches taken by ESO for the E-ELT and their North American counterparts, the Thirty Meter Telescope project.
