Since I last wrote, various different big telescopes have gone through some excellent stages. I shall attempt to summarise in chronological order, without overloading you too much...
The Very Large Telescope and KMOS
Back in November, KMOS achieved first light on the Very Large Telescope. You may remember, this is the instrument which my colleagues at the UK Astronomy Technology Centre were heavily involved in and was shipped out to Chile just as I was coming home. After its arrival at the Paranal Observatory in August, it was checked out (for any damage during shipping etc.) and then fitted to the Nasmyth platform in September and October.

Visible and Infrared Survey Telescope for Astronomy (VISTA) celebration
At the start of this year, in January, the Royal Observatory Edinburgh hosted a meeting called 'VISTA: A Celebration'. This meeting brought together many of the scientists and engineers who have been involved in this project over the years. There were talks about the planning and construction, as well as talks about the fantastic science VISTA has done so far and talks about the future.
VISTA has been operational since late 2009 and has given us some spectacular images including this amazingly detailed image of the Milky Way
Using this data from VISTA, astronomers have been able to create a catalogue of over 84 million stars in the central parts of the Milky Way. Wow!
Atacama Large Millimeter/Submillimeter Array (ALMA) Inauguration
In March this year, ALMA had its official inauguration ceremony - this marked the formal transition from a construction project to a fully fledged observatory, although not all the dishes are actually in place just yet at the Operations Site.
At work, we gathered in the canteen to watch the live stream of the celebration from Chile and even had an ALMA cake to enjoy!!
Since first light in 2011, with a partial array of just 16 dishes, ALMA has already given some very interesting science results about galaxies, planet formation and stellar evolution.
When I visited ALMA, there were just 34 dishes in place at the Operations Site. As of 29th May there were 59 antennas in place. I was very excited back in February, as the final North American dish was put in place at the 5000m site. When I visited the Operations Support Facility back in July last year, I posted a photo showing the final North American dish still in the construction hanger. Just goes to show that the construction of the dish itself is just one part of the whole process of building the observatory.
The latest ALMA press release sheds light on how dust particles in the disc around a young star can clump together to start to form things like comets and planets. You can read the full press release on the ESO website.
European Extremely Large Telescope (E-ELT) - UK support confirmation
Also in March this year, we had confirmation that the UK will participate in the E-ELT project - great news for my colleagues at the UK ATC. Since then, Portugal and Denmark have both confirmed their participation in the project too, and Danish company Ramboll have secured the contract to provide consultancy services to ESO during the construction of the huge dome required for the E-ELT. Construction of the E-ELT will hopefully start later this year.
James Webb Space Telescope (JWST) update
The last blog entry I wrote was about the second of the instruments for JWST having been delivered to Goddard, keeping the UK ATC led MIRI company. In May, the MIRI was installed into the structure which will hold all the flight instruments.

So, I think that about does it for a brief round of the main big telescopes news since I last wrote. The next few entries are actually going to be 'guest' blog entries from 2 friends who are out in La Palma.
