Simply Awesome Time-Lapse – Atacama Chile

A stunningly beautiful timelapse video of the night sky over Atacama Chile—and the music is awesome too!2012_antenna_0061 Our modern world denies most of us the wonder and pleasure of reflecting while looking at the stars. If you are not mesmerized throughout this video you need to check your pulse. Make sure your volume is up!

Some background on the VLT (Very Large Telescope)

The Very Large Telescope array (VLT) is the flagship facility for European ground-based astronomy at the beginning of the third Millennium. It is the world’s most advanced optical instrument, consisting of four Unit Telescopes with main mirrors of 8.2m diameter and four movable 1.8m diameter Auxiliary Telescopes. The telescopes can work together, to form a giant ‘interferometer’, the ESO Very Large Telescope Interferometer, allowing astronomers to see details up to 25 times finer than with the individual telescopes. The light beams are combined in the VLTI using a complex system of mirrors in underground tunnels where the light paths must be kept equal to distances less than 1/1000 mm over a hundred metres. With this kind of precision the VLTI can reconstruct images with an angular resolution of milliarcseconds, equivalent to distinguishing the two headlights of a car at the distance of the Moon.

The 8.2m diameter Unit Telescopes can also be used individually. With one such telescope, images of celestial objects as faint as magnitude 30 can be obtained in a one-hour exposure. This corresponds to seeing objects that are four billion (four thousand million) times fainter than what can be seen with the unaided eye.

The large telescopes are named Antu, Kueyen, Melipal and Yepun.ESO, the European Southern Observatory, is the foremost intergovernmental astronomy organisation in Europe
