ALMA opens its eyes

As the BBC report, and see here also, the European Southern Observatory (ESO) have released the first image obtained by their new telescope, the Atacama Large Millimetre/Sub-millimetre Array (ALMA) – even though the array isn’t expected to be completed until 2013.  It’s the focus of the latest ESOcast 36 – ALMA opens its eyes.

And here’s that image, of the colliding spiral Antennae Galaxies (also known as NGC 4038 and 4039).  [Image credit: ALMA (ESO/NAOJ/NRAO)]

Finally, from the people who brought us the wondrous sky above the VLT, here’s some, equally wondrous, time-lapse footage of the Chilean night sky above ALMA.  [Video credit: Footage – ESO/José Francisco Salgado and ESO (www.eso.org) (www.josefrancisco.org).
