As the chill of winter settles into the northern hemisphere, fantasies of down-south travel pervade a lot of people’s dreams. Well, here’s a virtual journey to warm climes for astronomy buffs: a beautiful, music-filled timelapse of several European Southern Observatory telescopes gazing at the heavens in Chile.
Uploaded in 2011 (but promoted this morning on ESO’s Twitter feed), the timelapse was taken by astrophotographers Stéphane Guisard (also an ESO engineer) and José Francisco Salgado (who is also an astronomer at Chicago’s Adler Planetarium.) Telescopes include:
We’ve covered their work before on Universe Today. In 2009, Guisard participated in GigaGalaxy Zoom, which produced a 360-degree panorama of the entire sky. He also released a 3-D view of several telescopes that same year. Also, Guisard and Salgado collaborated on another 2011 timelapse of the Very Large Telescope and nearby sites.
