New laser-sharp vision for Paranal’s facilities! 😎

In this image, you see the first of nine new lasers that are being built for our Extremely Large Telescope (ELT), currently under construction, and Very Large Telescope Interferometer (VLTI), both located at Paranal in #Chile

The laser projection systems are being built in the Netherlands, and the first one has now successfully passed a review by our engineers ✅ 🎉

🤔 But why do telescopes need lasers? They excite sodium atoms high up in the atmosphere, creating artificial "stars". By monitoring these "stars" we can measure and correct atmospheric turbulence in real time with a fast deformable mirror, obtaining very sharp images!

At the centre of the image, a big square machine is standing, its top part a closed grey box, containing a laser, resting on top of an illuminated network of intricate machinery. It is standing on a yellow slider. To the right of the machine, a man wearing safety goggles and gloves is standing on a stepping ladder, installing a part on a big black vertical tube, as high as he is, attached to the back of the square machine. On top, the tube is glowing yellow.
