The Galactic Centre is a pretty special place. A supermassive black hole, some of the most massive stars in spectacular clusters, and swirling clouds of gas and dust, all coexist at the heart of the Milky Way. And it looks quite pretty too. This is a new picture obtained with the near infrared camera ISAAC on one of the 8-m VLT Unit Telescopes.

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.
Pretty Valaparaiso in 2005
I noticed a lot of traffic to the blog today from google searches for people looking for info on the fate of the telescopes in Chile after last weekend’s huge earthquake that has devastated the central part of the country. The bottom line is that they all seem to be fine – although let’s not forget that the damage to Chile’s infrastructure could easily pay for hundreds of VLTs. As for the lives lost, well, no hardware can replace those.
On a personal note, my only experience of earthquakes dates back to 2005, while observing at Gemini South at Cerro Pachon, near La Serena in Chile. In our week-long observing run we suffered 2 earthquakes of magnitudes 5.8 and 5.0 or so, if I remember correctly. Our telescope operator, recognising the distant rumble, gave us a few seconds’ warning that a quake was under way, giving me ample time to freak out completely. Having just escaped the London bombings a few weeks earlier, I guess my nerves were pretty shot, but it was still pretty scary. I can only imagine how terrifying a magnitude 8+ quake must be when you’re sound asleep in your home at 3 am and I truly hope I never get to find out.
Anyway, here’s a round-up of some of the statements released by the astronomy organisations with bases in the country.
